Setting the global standard for advanced composite reinforcement, POLYMER operates as a premier binder free fiberglass mat supplier. Our heavy-duty fiberglass stitched mat is meticulously engineered by mechanically locking precisely chopped strands to a polyester or carbon tissue base, completely bypassing the need for chemical adhesives.
This innovative architecture delivers extraordinary dimensional stability and functions as a fast wet-out stitched fiberglass mat across UP, VE, and Epoxy resin systems. By dramatically accelerating resin impregnation, it serves as the ultimate structural backbone for continuous fiberglass mat for pultrusion profiles and high-pressure RTM closed-mold operations.
Representing the pinnacle of binder-free reinforcement technology, POLYMER's premium fiberglass stitched mat is a highly advanced composite substrate. As a leading stitched chopped strand mat manufacturer, we meticulously engineer this fabric by uniformly dispersing precisely chopped E-glass strands and mechanically locking them together using a high-strength polyester stitching yarn, completely bypassing the need for chemical binders.
This innovative binder free fiberglass mat architecture creates micro-channels throughout the fabric, guaranteeing an exceptionally fast wet-out speed (≤60s). It provides massive multi-directional strength and extraordinary dimensional stability that prevents fiber wash-out under high pressure. Fully compatible with Polyester, Vinyl Ester, and Epoxy resins, it is the globally preferred reinforcement for automated pultrusion profiles, closed-mold RTM (Resin Transfer Molding), and high-tension filament winding operations.
Whether you are pulling high-stress architectural beams or infusing complex automotive parts, our mechanically stitched mats secure your production efficiency:
For Continuous Pultrusion Operations: Leverage our fiberglass mat for pultrusion profiles. The tight polyester stitching prevents tearing when pulled through tight dies, ensuring flawless, high-strength I-beams, grating, and tool handles.
For RTM & Closed Mold Fabrication: Deploy our specialized RTM process stitched fiberglass mat. The binder-free structure ensures uninhibited, rapid resin flow, eliminating dry spots in intricate automotive housings and wind turbine components.
For Filament Winding & Anti-Corrosion: Utilize our filament winding fiberglass stitched mat to add a highly resilient, resin-rich inner layer to chemical storage tanks and heavy-duty FRP pipes, dramatically extending their service lifespan.
For Specialized Surface Finish Requirements: Source highly customized options directly from us. We offer specialized variants incorporating a polyester veil for superior weather resistance, or a carbon tissue backing for anti-static and conductive properties.
Mechanically stitched without chemical adhesives. This eliminates resin incompatibility, ensures a cleaner laminate, and vastly improves the mechanical strength of the final part.
The absence of binders combined with precise stitching creates micro-channels, allowing UP, VE, and Epoxy resins to impregnate the mat in under 60 seconds.
The robust polyester yarn securely locks the chopped strands in place. The mat will not stretch, tear, or thin out when subjected to the intense pulling forces of pultrusion dies.
Unlike standard emulsion mats, the stitched structure completely prevents fibers from "washing out" or shifting when resin is injected under high pressure in closed molds.
