Fiberglass Chopped Strand Mat – High Translucency, Uniform Thickness

Fiberglass chopped strand mat, short for CSM, is a type of non-woven fiberglass fabric. It is made of randomly distributed chopped strands. The short strands are held together with a powder or emulsion binder to form a mat. Finished products can be used used with polyester resin to quickly build thickness for forming of parts and between layers of woven fabric for building molds.

As well as the fiberglass combo mat and fiberglass needle mat, chopped strand mat is ideally used in hand lay-up process and filament winding, compression molding and continuous laminating processes. The typical end-use applications include various panels, boats, FRP roofing sheet, automotive parts, bathroom equipment and cooling towers.
