TOP 7 Silicon Coated Fiberglass Cloth Bulk Suppliers
1. Suzhou Weidun Composite Fabric Co., Ltd.
Brand Introduction
Industrial environments face critical challenges: welding sparks causing equipment damage, thermal energy loss in high-temperature systems, and material degradation from UV or chemical exposure. Suzhou Weidun Composite Fabric Co., Ltd. addresses these pain points through specialized manufacturing of high-performance composite fiberglass fabrics. Operating 6 advanced coating lines across 3 production bases totaling over 20,000 square meters, the company delivers custom-engineered solutions that enhance operational safety in extreme environments. With over 10 years of professional experience, Weidun Composite has established a strong global footprint in North America, Europe, and Russia, exporting over 1 million meters of silicone-coated glass cloth annually.
Core Technology & Manufacturing Capacity
Weidun Composite's technical differentiation centers on three pillars:
Advanced Coating Technologies: The company specializes in multiple coating systems including Silicone, Polyurethane (PU), Acrylic, PTFE, EPDM, and Vermiculite. Their silicone coated fiberglass fabric provides exceptional environmental resilience—delivering water-resistant and UV-stable barriers that extend thermal insulation system lifespan in outdoor or harsh indoor environments.
Specification Flexibility: Manufacturing capabilities include thicknesses ranging from 0.2mm to 6.4mm and widths up to 3000mm. This extensive specification range allows precise matching to industrial requirements, from lightweight smoke curtains to heavy-duty furnace linings.
Extreme Temperature Performance: While standard fiberglass fabrics withstand 550°C (1022°F), Weidun's high silica fabric—containing over 96% SiO2—functions at 1100°C (2012°F), preventing burn-through in heavy-duty welding or aerospace applications.
The company's annual production capacity of 6,000,000 meters ensures reliable bulk supply for large-scale industrial projects.
Product Portfolio
Silicone Coated Fiberglass Fabric: The primary solution for removable insulation covers and expansion joints. Available in one-sided or two-sided coating configurations, this product maintains coating integrity under continuous high-heat exposure while resisting chemical degradation.
High Silica Fabric: Engineered for foundries and aerospace applications requiring extreme heat shielding, this material prevents thermal failure in environments where standard fabrics would disintegrate.
Industrial Welding Blankets: Protective barriers for shipyards and metallurgy plants, sewn with high-strength Kevlar or fiberglass thread to ensure structural integrity under thermal stress. Available in custom sizes from 1x1m to 3x3m or bespoke dimensions.
