Can PVC foam board be glued with other materials?
PVC foam board is an ideal material for decoration. However, sometimes we need the various options of the surface so that could strength the beauty and practicability. Therefore, it is necessary to glue all kinds of patterns or other plastic boards with PVC foam board. Then the question is Can PVC foam board be glued with other materials? What kind of material could be glued with PVC foam board perfectly? PVC foam board could be definitely glued with other materials. The common materials which could be glued with PVC foam board are as below:
1. PVC wood grain film
PVC wood grain film is used widely in decoration, and it could be laminated to the surface of PVC foam board well, which makes the surface looks more beautiful. The regular method to do the gluing is flatbed press gluing.
During the process of gluing, the following should be paid attention to:1.1 PVC wood grain film must be back-coated, otherwise it will not be easy to glue, not paste well in the process of laminating.1.2 Usually make one side of PVC wood grain film adhesive with roller coating or blade coating.1.3 Glue coating must be homogeneous and same thickness to ensure no glue missing and no glue accumulate on the board. The thickness of glue coating should be adjusted according to the thickness of film and weather.1.4 Time after glue before coating, summer or autumn season with hot and dry condition, time can be shorter, while and cold and humid winter and spring, time can be longer. The best gluing timing is when touching the surface of the glue with fingers, feeling it is almost dry but sticky, and then keeping it on the exact position, sticking the both sheets with flatbed pressing. How long the time needed to do the gluing is determined by the thickness of the coating, the speed of doing the coating and the temperature of the environment.
2. Tempered Glass
Tempered glass laminated PVC foam board is a new laminated way in recent years, tempered glass has the advantages of high safety, high strength, good thermal stability, UV stable and so on, which is widely used in benchtop, countertop, coffee top, building doors and windows and so on.
The surface of PVC board can also be glued with acrylic. Acrylic, also known as PMMA, has good transparency, chemical stability and weather resistance, beautiful appearance, has been widely used in the construction industry and decoration field.
4.Decorative High-pressure Laminate
Fire waterproof board is also known as refractory board. Its scientific name is high-temperature laminated board of thermosetting resin impregnated paper. The abbreviation is HPL (High-pressure Laminate). HPL board is a fire-resistant building material for surface decoration. It has rich surface color, texture and special physical properties. Undoubtedly, HPL can also be laminated with PVC foam board, which enriches the surface of the foam board and can be widely used in interior decoration, furniture, cabinets, laboratory countertops, exterior walls and other fields.
The Difference of Production Technology and Performance between HDPE and UHMW-PE
Generally HDPE’s production technology is extrusion, including three roll calender process and plate shaping process.And the production technology of ultra-high molecular weight PE (UHMW-PE) is compression molding pressing.
In terms of thickness, the two types of products can be divided as:
1. Less than 25mm, the PE sheets are usually produced by extrusion calender process.2. More than 25mm, the PE sheets can be produced either by extrusion plate shaping or by compression molding pressing.The sheets produced by calender process, with very smooth surface, shinning like a mirror.The sheets produced by compression molding pressing process, with not smooth and shinning surface.
Molecular weight of HDPE and UHMW PE:
HDPE usually refers to the PE sheet with molecular weight less than 1.5 million;High molecular weight PE refers to PE sheet with molecular weight more than 3 million; There are 3 million, 5 million, 7.5 million, 10 million etc. molecular weight PE. The higher the molecular weight, the better the wear resistance.Ultra-high molecular weight PE has excellent properties of wear resistance, impact resistance, low temperature resistance, corrosion resistance, sanitation and non-toxicity.
Wear-resistance testing method:1. Make the workpiece for wear-resistant testing first;2. Place the workpiece in the wear-resisting testing instrument, continuously wear the workpiece at the set speed and time;3. The whole testing takes at least 3 hours.
Performance differences between HDPE and UHMW PE:Chemical resistance: both materials have excellent chemical resistance and can be used in 95% chemical environments.HDPE can't resist the corrosion of concentrated hydrochloric acid, sulfuric acid and nitric acid in high temperature, and UHMW-PE can be used to store 80 ° C hot concentrated hydrochloric acid, sulfuric acid and nitric acid, and have stable performance.Impact resistance: HDPE and UHMW-PE have much better impact resistance than other plastics, such as PP, PVC. To Compare HDPE and UHMW-PE, the impact resistance of UHMW-PE is obviously better than that of HDPE, and its impact resistance absorption value is the highest among all plastics. Therefore, it is widely used in the mechanical workpieces of ships, aircraft and machine tools. Low temperature resistance: HDPE can maintain good mechanical properties at low temperature - 30 ° C. UHMW-PE can still maintain excellent impact strength at -196 ° C in the liquid nitrogen, not brittle. Among all plastics, UHMW-PE has the best low temperature resistance.
What Kind Of Printing Can Boardway's Foamed PVC Sheet Be Used For?
Boardway's foamed PVC sheet is widely used in various industries due to its excellent waterproof, light weight, flame retardant, easy printing, and engraving properties. Advertising signs is one of the main applications. PVC free foam board and PVC celuka foam board, as well as PVC co-extruded foam board can be used for printing.
Suitable for no more than 4 single colors in printing at a time. Compared with UV printing, screen printing inks are thicker, so colors end up looking much better. Besides, screen printing costs lower than UV printing.
Silk Printing Factory
UV printingCompared with screen printing, the colors of UV printing are more comprehensive and more vibrant. When the selected HD image finished layout design and positioning, the printing can start right away.The ink jet printer doesn't limit the minimum quantity of printing, so UV printing is very suitable for small batch production or individual product.
Both two printing methods have high requirements on the surface of PVC foam board, so the surface must be cleaned before printing. To ensure the printing effect, the surface must be free of dust and stain without holes or scratches.
How To Distinguish Between HDPE and Polypropylene?
PolypropyleneA synthetic resin built up by the polymerization of propylene.It can be divided into copolymer polypropylene and homopolymer polypropylene.Polypropyleneis non-toxic,tasteless and waterproof with low density, which can be used at around 100℃.It has good chemical stability and is almost stable except for hot concentrated sulfuric acid, concentrated nitric acid and concentrated alkali attacking.It has excellent high frequency electrical performance and is not affected by temperature, and is easy to be formed as well.
While they have some disadvantages as well.1. Wear resistance is not good enough.2. Shrinkage occurs upon cooling after thermal processing.3. It is easy to crack under low temperature.4. Low thermal deformation temperature than HDPE's.
Polyethylene A thermoplastic polymer with variable crystalline structure and an extremely large range of applications depending on the particular type. PE is odorless, non-toxic, feeling like wax with excellent low temperature resistance (minimum use temperature can reach -100~-70 °C). It has stable chemical properties and is resistant to most acids and alkalis (not resistant to acids with oxidizingproperties). It is insoluble in common solvents at room temperature, has low water absorption and excellent electrical insulation.
PE are basically divided into three categories: LDPE, HDPEand LLDPE.HDPE is a high-density polyethylene, which is called "HighDensityPolyethylene" or "HDPE". HDPE is a highly crystalline, non-polar thermoplastic resin.Main features: non-toxic, odorless, odorless, melting point is about 130 °C. It has good heat resistance and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength. Dielectric properties and environmental stress crack resistance are good as well.
Both PP and HDPE can be used for food packaging, and they look similar in appearance. But what are the main differences between the two?
1. HDPE has higher strength and stiffness than PP.2. PP is more translucent than HDPE.3. HDPE has better performance on heat resistant, low temperature resistance, anti-aging and toughness than PP.4. The price of PP is slightly lower than HDPE.5. In terms of application, since HDPE performs better than PP in rigidity and strength, it is often used as mechanical parts and components. While PP is often used to make sinks, plating tanks or containers.
So how can we distinguish between PP and HDPE?1.By TouchingThe surface and sides of the HDPE board are smoother, while the cut surface of the PP board has some burrs and feels rough. Therefore, they can be distinguished by touching the surfaces.2. By Burning

When we engrave on a PVC foam board, how can we ensure its engraving surface is smooth?
PVC foam board, an ideal material that is widely used in advertising, furniture cabinets and interior decoration etc. PVC foam boards are often used to engrave into a variety of designed shapes. So how can an engraving surface be smooth without burrs, showing a beautiful appearance? There are some tips for your reference.
Choose a PVC foam board suitable for engraving. From the technical point of view, PVC celuka foam board should be given priority, followed by PVC co-extruded foam board and PVC free foam board; In terms of density, try to choose the foam board with a density higher than 0.5g/cm3; In terms of the appearance, select a foam board without bubbles in the cross section.The quality of PVC foam board is a key factor that contributes to the smoothness in the engraving.
Engraving Partition Wall
First, the appropriate engraving tool should be selected according to the design pattern. There are many types of engraving tools, of which the diameter, length, and shapes are different. Single blade, double blade, flat bottom, pointed bottom and round bottom; diameter ranging from 3.175mm, 4mm, 5mm, 6mm, 8mm, 10mm etc. And then comes to cylindrical shape, V-shaped and slotted shaped etc. Secondly, the long-term use of the engraving tool will cause itself to wear seriously and become blunt, resulting in a non-smooth cutting surface. Therefore, it is necessary to change the tool regularly to ensure a smooth cutting surface. It is advised to choose the right tool and carefully observe it during the engraving process. If the cutting surface is not smooth, please replace the tool in time.
Path settings for engraving toolBoth the path setting of the engraving tool and its rotating directionhave a great influence on the smoothness of the cutting surface. You can improve the smoothness of the cutting surface by changing the tool’s direction in the software.For example, when producing embossing effect on the board and trimming straight edges along it, we can use the pointed knife to make surface engraving. Then, change to straight knife for trimming. So you can see this is a process that is completed by two types of engraving tools.If the customer does not require the edge of the product to be straight, then it is usually carved and cut with only a pointed knife, saving the trouble of changing knifes during the process. However, the finished cutting will be a bit angled. Some customers with low requirements think it acceptable, and the processing price is relatively cheaper. If the customer wants the cutting edge to be straight, it must be cut with a straight knife and the processing cost will increase.
The straight knife is trimming.
Rotating speed and running speed of the engraving toolThe engraving tool that rotates and runseither too fast or too slowly will result in rough engraving. Therefore, we should adjust the rotating and running speed to find a balance between engraving effect and economic benefit. Apart from that, we need to sum up experience during the process to find the most suitable rotating and running speed.
Can corrugated plastic sheet, plastic honeycomb panel and X type twin wall hollow sheet be used outdoors?
If the above 3 kinds of PP corrugated sheets are to be used for a long time under the conditions of sun and rain, they need to be able to resist aging. So, how can we slow down the aging speed of these PP corrugated sheets?First of all, we need to know the outdoor conditions where the PP corrugated sheets are used:1. Intensity of sun exposure (annual average ultraviolet radiation, continuous data of at least 10 years)2. Humidity and annual precipitation3. The lowest temperature
PP Corrugated Sheet
View more about Boardway's PP corrugated sheet.
PP Honeycomb Sheet & X Type Twin Wall Hollow Sheet
View more about Boardway's PP honeycomb sheet and X type hollow sheet.
Besides, we also need to know how long the PP corrugated sheets can be used.Generally speaking, PP corrugated sheets for outdoor use are applied to advertising, carriages and construction sites etc. The life span depends on using environment and these sheets' application.
The higher the ultraviolet light, the more precipitation, the more humid the environment, and the lower the temperature, the aging speed of the PP plastic hollow board will be faster.PP corrugated sheets are deteriorated by light, heat, moisture, oxidation and other factors, which cause the material to fade and lose its original mechanical properties.
After adding anti-UV agent to the sample, the change is not obvious after 12 months of sun and rain.(from Jan 2018 to Oct 2018)
However, the sample without the anti-UV agent has a poorer effect for outdoor use under the same weather condition for 12 months
Therefore, to slow down the aging rate of PP corrugated sheets, the production formula can be appropriately adjusted according to different uses as follows:1.Adding appropriate ultraviolet light absorber and antioxidant can effectively improve the sheets' weathering resistance.2.To maintain the durability of the color, it is necessary to add weathering pigment to adjust the color of the swatch, such as iron oxide red, phthalocyanine blue, carbon black, green, and dioxin color, which can improve its weather resistance.3.In the polypropylene hollow sheet formula, adding an appropriate amount of dioxins can greatly improve the weathering resistance.4. In the polypropylene hollow sheet formula, a certain antimony stabilizer is added to replace the lead salt stabilizer, which has a corresponding improvement on the impact toughness and atmospheric aging resistance.
For Boardway (Polyreflex's) plastic sheets, life spans of different products are as below:1. PP corrugated sheets can be used outdoors for 2 years. UV Absorber2. Plastic honeycomb panel and X type twin wall hollow sheet: Standard products can be used outdoors for 3 years; if there are special requirements like extending the life span of the product, high-quality UV absorber can be added to meet more than 5 years service life.
