Import Chopped Strand Mat — Buy in Bulk from Supplier in China

The chopped strand mat from Tianjin Zhongtian Junda Glass Fiber Products Co., Ltd consists of randomly distributed E-glass fibers bonded with a water-soluble emulsion binder, forming a flexible, non-woven sheet. The mat has a standard area weight range of 150 g/m² to 450 g/m², with thickness varying from 0.8 mm to 2.5 mm depending on density. The fibers are cut to lengths between 10 mm and 50 mm, optimized for resin penetration and mechanical reinforcement in composite laminates.

E-glass chopped strand mat is the industry standard for hand lay-up and spray-up processes in marine, automotive, and wind energy sectors. The binder used is typically polyvinyl alcohol (PVA), which dissolves during resin curing and leaves no residue. The mat is designed for compatibility with polyester, vinyl ester, and epoxy resins. No roving or continuous filament is present - this is purely a discontinuous fiber reinforcement system.

This product is commonly used by composite fabricators producing boat hulls, automotive body panels, and wind turbine blades. Buyers require consistent areal weight, low linting, and uniform fiber distribution. The mat is supplied in rolls of 1 m or 1.25 m width, with lengths up to 100 m. Packaging is in plastic-wrapped cardboard cores. Trade terms are FOB Tianjin or CIF. Lead time is not stated and must be confirmed. MOQ is not specified and must be requested directly.
