Versatile Fiberglass Chopped Strand Mat Roll Chemical Resistant Continuous Strand Mat

Chopped Strand Mat | Marine-Grade Boat Hull Lamination And Industrial FRP Reinforcement​


1. Product Introduction​

Chopped Strand Mat (CSM) is a non-woven fiberglass reinforcement material engineered for exceptional durability and versatility. Composed of randomly oriented E-glass or C-glass fibers bonded with polyester or emulsion binders, it delivers uniform strength, rapid wet-out, and excellent moldability. Ideal for hand lay-up and open-mold applications, CSM ensures consistent fiber distribution for high-performance composites in marine, automotive, and construction industries.


​2. Production Process​

​Step​

​Description​

​Fiber Cutoff​

Continuous glass rovings are cut into 1.5–3 inch lengths for uniform distribution.

​Binder Application​

Fibers are bonded using polyester powder or emulsion binders for structural integrity.

​Random Distribution​

Cutoff fibers are spread evenly on a moving belt to form a non-woven mat.

​Curing​

Heat treatment activates binder curing, ensuring dimensional stability.

​Quality Control​

Parameters like weight (100–900 g/m²), thickness (0.045–0.12 inches), and adhesion are tested.


​3. Usage Precautions​

  • ​Storage​​: Keep in dry, cool environments (15–35°C) away from humidity and direct sunlight.

  • ​Temperature Limits​​: Operate within -40°C to 120°C; avoid prolonged exposure to extreme heat.

  • ​Chemical Resistance​​: Compatible with polyester, vinyl ester, and epoxy resins. Avoid contact with strong acids or solvents.

  • ​Handling​​: Wear gloves to prevent fiber irritation; use sharp cutting tools to minimize fraying.
