Chopped strand mat is made from fiberglass strands chopped to length and bonded together with powder/emulsion binder. Chopped strand mat is used primarily for hand lay-up processes, filament winding and press molding of FRP products. Typical products include bathroom accessories, pipe, building materials, automobiles, furniture and other FRP products. Packing: Each roll should be winded onto a paper tube and then wrapped up with plastic film, which should be packed in a cardboard box.
