CSM Chopped Strand Mat

Chopped Strand Mat (CSM) is a non-woven glass fiber reinforcement material made from E-glass fibers chopped into 50mm length, randomly and uniformly distributed, and bonded with powder or emulsion binder. It is mainly suitable for hand lay-up and mechanical molding processes, featuring fast resin wet-out, excellent moldability, and easy handling.
