Why Choose Our Chopped Strand Mats?
Rapid Wet-Out & Multi-Resin Compatibility
Our fiberglass CSM features optimized binder chemistry ensuring fast resin penetration and air release. It performs exceptionally well as a polyester resin fiberglass mat, a tough vinyl ester fiberglass mat, and a reliable fiberglass mat for epoxy resin systems.
Process Versatility
Designed for maximum drapability and handling ease, it is the industry standard fiberglass mat for hand layup. It also provides excellent mechanical strength for automated filament winding fiberglass mat operations and high-pressure press molding fiberglass mat processes.
Our specialized CSM product portfolio serves diverse industries:
Marine & Automotive: High-strength chopped strand mat for boat building and lightweight automotive fiberglass mat designed for creating durable hulls, decks, and vehicle body panels.
Industrial Anti-Corrosion: Heavy-duty anti corrosion fiberglass mat perfectly suited for manufacturing chemical-resistant pipes, inner liners, and robust cooling tower fiberglass mat components.
Sanitary & Construction: Easy-to-mold reinforcements for bathroom accessories, bathtubs, and architectural panels ensuring a smooth, defect-free surface finish.
