Empowering Precision, Defining Efficiency.
E-glass Chopped Strand Mat (CSM) is made of randomly distributed chopped E-glass fibers bonded together with a powder or emulsion binder. This mat provides uniform reinforcement, excellent strength, and superior resin compatibility, ensuring consistent composite quality.
Widely used in applications such as FRP boats, bath equipment, automobiles, chemical tanks, cooling towers, and furniture, CSM enhances durability and structural integrity in fiberglass-reinforced products.

▪ Made of randomly arranged short E-glass fibers
▪ Fibers held together with a powder or emulsion binder
▪ Non-woven mat for even strength in all directions
▪ Provides consistent reinforcement across the entire mat
▪ Good strength to support composite parts
▪ Binder keeps fibers in place during making and curing
▪ Works well with polyester, vinyl ester, and epoxy resins
▪ Used in hand lay-up, spray-up, and resin transfer molding (RTM)
▪ Absorbs resin evenly for smooth and strong parts
▪ Boats and marine parts
▪ Bathtubs and sanitary ware
▪ Car parts
▪ Chemical tanks and storage
▪ Cooling towers and furniture
▪ Often combined with woven fabrics for better strength
▪ Choose resin based on environment for better durability
▪ Adjust mat weight to fit strength needs and budget
One roll is wrapped in plastic film and then placed into a carton or a large carton.
Normally, P4 (4 big rolls) or P7 (4 big rolls + 3 small rolls) or 6, 9, or 12 small rolls are packed per pallet horizontally/vertically. It can be customized based on the loading method.
Fiberglass products should be stocked in a dry, cool, and waterproof place. The best condition is with a temperature between 15-35℃, with a relative humidity between 30%-65%. Please keep the product in its original packaging before use, avoiding moisture.
