Setting the global standard for advanced composite reinforcement, POLYMER operates as a premier manufacturer of high-performance fiberglass stitched fabric. Meticulously engineered without chemical adhesives, this binder-free fiberglass stitched mat utilizes precision mechanical stitching to lock the glass strands securely in place, delivering exceptional dimensional stability and massive structural strength.
By completely eliminating the chemical barrier, this fast wet-out fiberglass stitched fabric guarantees rapid resin impregnation and flawless compatibility with Polyester, Vinyl Ester, and Epoxy systems. It serves as the ultimate reinforcement for heavy-duty stitched fabric for pultrusion pipes, continuous filament winding tanks, and high-pressure RTM process fiberglass fabric applications across the marine, automotive, and anti-corrosion industries.
Setting the global standard for closed-mold efficiency, POLYMER's multiaxial core mat is an innovative, high-performance sandwich-structured reinforcement. As a premier fiberglass stitched core mat manufacturer, we meticulously engineer this complex fabric by mechanically stitching three distinct layers together without chemical binders: a structural biaxial fiberglass base (0°/90°), a highly permeable synthetic flow core (such as PP, PET, or Nylon), and a top layer of chopped fiberglass strands.
This highly advanced sandwich structure fiberglass mat dramatically increases the stiffness-to-weight ratio of the final composite part. The central synthetic core acts as an ultra-fast highway for resin, making it the ultimate fast resin flow core mat. Highly compatible with Polyester, Vinyl Ester, and Epoxy resin systems, it is universally specified as the premier reinforcement for manufacturing lightweight, high-strength structures via vacuum infusion core mat processes, automated RTM (Resin Transfer Molding), and heavy-duty marine applications.
Whether you are infusing massive luxury yacht hulls or molding lightweight automotive components, our engineered core mats secure your production efficiency and structural integrity:
For RTM & Closed Mold Operations: Deploy our specialized RTM process fiberglass core mat. The highly permeable synthetic core guarantees ultra-fast resin injection across the entire mold cavity, completely eliminating dry spots and reducing cycle times in complex automotive and train parts.
For High-Performance Marine Hulls: Leverage our fiberglass core mat for boat hulls. By replacing heavy layers of standard roving, the sandwich structure allows you to build massive thickness and extreme torsional stiffness while significantly reducing the overall weight of the vessel.
For RV & Transportation Vehicles: Utilize our fiberglass core mat for RV bodies. The integrated core material not only provides structural rigidity but also adds excellent acoustic and thermal insulation properties to refrigerated trucks and camper vans.
For Regional Raw Material Distributors: Source an exceptional Rovicore alternative supplier directly from China. We offer fully customizable weights (from 930g to 1650g), tailored core thicknesses (e.g., 180g or 250g PP), and highly competitive factory-direct export pricing.
The synthetic middle core acts as a high-speed conduit for resin, ensuring incredibly fast and complete wet-out during Vacuum Infusion and RTM injection.
The integrated sandwich structure builds massive laminate thickness instantly, delivering extraordinary bending stiffness while significantly reducing the final part's weight.
All three layers are mechanically stitched together without chemical adhesives, eliminating resin incompatibility and preventing fiber wash-out under high pressure.
By laying down the structural fiberglass and the flow medium simultaneously in a single step, fabricators drastically cut manual labor time and reduce lay-up errors.
