What is chopped strand mat (CSTM)? What are its core advantages?

Fiberglass chopped strand mat (CSM) is a nonwoven fiberglass reinforced material made by chopping glass fibers, allowing them to settle uniformly without orientation, and then applying powder or emulsion binders.

It is primarily suitable for hand lay-up of fiberglass reinforced plastics (FRP) and mechanical molding processes. It is easy to process and has excellent molding properties. CSM has rapid resin impregnation, extremely high transparency, and uniform fiber distribution ensures good moldability and high strength after molding. CSM is widely used in skylights, cooling towers, chemical storage tanks, FRP pipes, sanitary ware, ship hulls and decks, and FRP truck body panels, etc. The company also offers lightweight CSM.
