Overview
Chopped Strand Mat is available in three grades, P20, P02, and P30, each compatible with unsaturated polyester, vinyl ester, and epoxy resins. As one of the recommended international brand products in our glass fiber range, it is supplied with supply chain resource support for fabricators sourcing chopped strand mat for hand lay-up, general purpose, and translucent panel applications.
Key Grades of Chopped Strand Mat
- P20: Soft mat, ease of manual tearing apart, good conformability, fast wet-out, rapid air release
- P02: High tensile strength for large-area hand lay-up parts, high mechanical strength, superior acid corrosion resistance
- P30: Fast wet-out, excellent translucency, high mechanical strength, superior acid corrosion resistance

Applications
P20 chopped strand mat is a soft mat with ease of manual tearing apart and good conformability, offering good wet-through and fast wet-out in resins with rapid air release, making it suited to marine and general hand lay-up work. P02 offers high tensile strength and is suitable for hand lay-up processes producing large-area parts, with high mechanical strength and superior acid corrosion resistance for building and construction use. P30 provides fast wet-out and excellent translucency, making it suited to lighting boards, with colors available upon request.
Why Grade Selection Matters for Chopped Strand Mat
Because Chopped Strand Mat is offered in three grades with different handling and performance characteristics, selecting the right grade for a specific process step can affect both fabrication speed and finished part quality. P20 is engineered to be soft and easy to tear apart by hand, which suits fabricators who need to conform mat around curves or details during hand lay-up, while P02 is engineered for high tensile strength and is positioned specifically for producing large-area parts where handling strength during layup matters more than conformability.
P30 is engineered around fast wet-out and excellent translucency, which are the properties that matter most for lighting boards and other applications where light transmission through the finished composite is a requirement rather than a side effect. Fabricators should always confirm current wet-out time, air release, and mechanical property data against the latest technical data sheet for their specific grade and resin system.
What to Consider When Sourcing Chopped Strand Mat
When sourcing chopped strand mat for hand lay-up, general purpose, or translucent panel applications, fabricators typically evaluate area weight, roll width, resin compatibility, and the specific grade characteristics, such as conformability, tensile strength, or translucency, needed for their process. Working with a supplier that can provide consistent documentation and responsive technical support can help reduce qualification time when approving a new chopped strand mat grade for a production line.
Because all three grades are compatible with unsaturated polyester, vinyl ester, and epoxy resins, fabricators switching between grades on the same resin system should still confirm current wet-out and air release performance for their specific process, since handling characteristics differ meaningfully between P20, P02, and P30 despite shared resin compatibility.
General Handling and Storage Guidance
As with most glass fiber mat products, this product should be kept in its original packaging, stored in a clean, dry location away from moisture and direct sunlight, and used within the manufacturer’s recommended shelf life. Because wet-out performance and handling can be affected by humidity and contamination, rolls should be resealed promptly after each use.
Shelf life and specific storage recommendations vary by batch and packaging format, so fabricators should always confirm current shelf life, recommended storage conditions, and any handling precautions against the latest technical data sheet and SDS for the specific batch and grade of Chopped Strand Mat they are working with.
