Is Expanded PVC the Same as Sintra or Forex?
Expanded PVC is a generic term that refers to a type of foam board made from PVC (polyvinyl chloride) that has been expanded to create a foam-like structure. On the other hand, Sintra and Forex are both brand names for specific types of expanded PVC foam board.

Sintra is a brand name for a type of expanded PVC foam board that was originally developed by the 3A Composites company. Sintra foam board is made using a proprietary manufacturing process that creates a closed-cell structure. Known for its exceptional stiffness, high-quality surface finish and consistent thickness, making it ideal for printing and graphics applications. It is commonly used for high-end signage, displays and exhibits that require high precision and professional finishing.

Forex is another brand name for a type of expanded PVC foam board that is produced by the Swiss company 3A Composites. It is known for its high-quality surface finish, dimensional stability, and resistance to moisture and chemical exposure. Forex foam board is also suitable for printing and graphics applications, but it is specifically designed for outdoor use due to its high resistance to moisture, UV light, and temperature changes. It is often used for outdoor signage, billboards, and displays that require long-term durability and weather resistance.
