Fiberglass chopped strand mat is a non-woven E glass fiber mat, product manufactured by spreading continuous filament roving of 50mm in length randomly in combination with polyester binder in powder form(or other binder in emulsion form). This product is characterized by good combination of resin, easy operation, good wet strength retention, good laminate transparency and low cost. Fibers and binder distributed equally, non-hairiness, stains and other defects debris; Resin saturated fast, good review mode, easy to eliminate air bubbles; Products with higher mechanical strength, wet strength retention of the high rate of dry; High tensile strength, reducing the occurrence of tearing production; Laminates smooth surface, good light transmission; Uniform thickness, no defects such as stains debris; Moderate hardness , easy to completely saturated, less bubble products quickly saturated; Speed , good technology and good erosion-resistant fiber; The mechanical properties with good filling and review mode and applicable to the products of complex shape forming; Good mechanical capability.
