→Fiberglass Chopped Strand Mat is an non-woven E- or C-glass fiberglass fabric manufactured by spreading continuous filament rovings of 50mm in length randomly and uniformly in combination with polyester binder in power form (or other binder in emulsion form).
Chopped Strand Mat (CSM) is a random fiber mat that provides equal strength in all directions and is used in a variety of hand lay-up and open-mold applications. Chopped strand mat is produced by chopping continuous strand roving into short 1.5 to 3 inch lengths and dispersing the cut fibers randomly over a moving belt to from a "sheet" of random fiber mat. A binder is applied to hold the fibers together and the mat is trimmed and rolled. Because of is random fiber orientation, chopped strand mat conforms easily to complex shapes when wet-out with polyester or vinyl ester resins. Chopped strand mats are available as a roll stock product produced in a variety of weights and widths to suite specific applications.
Fiberglass mat (also known as chopped strand mat) has strands of fiber that are randomly oriented and held together with a styrene binder. When a resin is added to the mat, the binder dissolves and the fibers can be moved around.Chopped strand mat is very strong due to the fiberglass fibers compressed together at random angles, can be used for Matched Metal Die wet molding, Open mold applications. Chopped Strand Mat is used to build up thickness quickly and is often layered in between fiberglass fabric. It is compatible with polyester and vinyl ester resin.
Mat Production Process
Assembled rovings are chopped to a specified length, and then fall onto a conveyor randomly. The chopped strands are bonded together by either an emulsion binder or a powder binder. After drying, cooling and winding, a chopped strand mat is formed.
Emulsion Chopped Strand Mat
Emulsion Chopped Strand Mats are made of randomly distributed chopped strands held together by an emulsion binder. They are compatible with UP and VE resins. The roll width ranges from 200mm to 3,120mm. Special requirements may be available upon request.
Powder Chopped Strand Mat
Powder Chopped Strand Mats are made of randomly distributed chopped strands held together by a powder binder. They are compatible with UP, VE, EP and PF resins. The roll width ranges from 200mm to 3,120mm. Additional demands on wet-out and decomposition time can be available upon request.

Storage
Unless otherwise specified, the fiberglass products should be in dry, cool and moisture-proof area. The room temperature and humidity should be always maintained at 15ºC~35ºC and 35%~65%. It is best if the price is used within 12 months after production date. The fiberglass products should remain in their original packaging until just prior to user.
