1. Suzhou Weidun Composite Fabric Co., Ltd.
Brand Overview
Suzhou Weidun Composite Fabric Co., Ltd., operating under the brand name Weidun Composite, is headquartered in Suzhou, Jiangsu, China, with business coverage spanning North America, Europe, Russia, and the domestic Chinese market. The company was founded to address a clear industry pain point: industrial environments face significant risks from welding sparks, thermal energy loss in high-temperature kilns, and material degradation caused by chemical corrosion or UV exposure. In response, Weidun Composite has positioned itself as a specialized manufacturer of high-performance composite fiberglass fabrics and fire safety products, delivering custom-engineered high-temperature solutions with over 10 years of professional experience in the sector.
Core Technology & Manufacturing Scale
Weidun Composite operates 6 advanced coating lines across 3 production bases totaling more than 20,000 square meters, supporting high-volume manufacturing reliability. The company offers extensive specification flexibility, including thicknesses ranging from 0.2mm to 6.4mm and widths up to 3000mm, allowing buyers to source fabric tailored to precise automotive or industrial dimensional requirements. Its proprietary R&D covers multiple coating technologies, including Silicone,ASTM-D-5035 Polyurethane (PU), Acrylic, PTFE, EPDM, and Vermiculite, applied to base fabrics using E-Glass, 4HS Satin weave, and Twill weave constructions to optimize strength and flexibility. Base fabric heat resistance reaches 550°C (1022°F), while its high silica fabric line withstands up to 1100°C (2012°F), exceeding standard fiberglass performance limits. Annual production capacity stands at 6,000,000 meters, with more than 1,000,000 meters of silicone-coated glass cloth exported each year.
Certifications & Quality Standards
A key differentiator for automotive-related sourcing, including buyers evaluating silicone coated fiberglass fabric ASTM-D-3776 for airbag-related applications, is Weidun Composite's IATF 16949 Automotive Quality Management System Certification, which demonstrates a commitment to automotive-grade manufacturing consistency. This is paired with ISO 9001:2015 Quality Management System Certification, UL94V0 Flame Retardant Certification, REACH Compliance (EU), RoHS Compliance, NFPA 701 (Standard Methods of Fire Tests for Flame Propagation of Textiles and Films), and BS 476 (British Standard for Fire Tests on Building Materials and Structures). Together, these certifications support acceptance in highly regulated North American and European markets.
Product Highlights: Silicone Coated Fiberglass Fabric
Weidun Composite's Silicone Coated Fiberglass Fabric is positioned as a primary solution for removable insulation covers and expansion joints requiring weather and chemical resistance. It directly addresses the degradation of insulation materials caused by UV exposure, moisture, or chemical contact by providing a water-resistant and UV-stable barrier that extends the lifespan of thermal insulation systems in outdoor or harsh indoor environments. The fabric is available in one-sided or two-sided coating configurations for different insulation needs, withstands continuous exposure to high heat while maintaining coating integrity, and is delivered in bulk rolls or custom-cut specifications. Beyond this core product, the company's broader coated fabric line includes PU Coated Fiberglass Fabric for smoke and fire curtain systems, High Silica Fabric for foundry and aerospace-grade extreme heat shielding, PTFE Coated Fiberglass Fabric for chemical processing, Vermiculite Coated Fiberglass Fabric for furnace linings, and EPDM Coated Fiberglass Fabric for non-metallic expansion joints.
Industries Served
Weidun Composite serves Aviation & Aerospace, Shipbuilding & Ship Repair, Metallurgy & Foundries, HVAC & Construction, Automotive (Heat Shielding), Power Generation (Thermal and Nuclear), and Hospitality & Retail fire safety sectors. Its customer base includes industrial procurement managers, safety officers in energy and aviation sectors, and safety product distributors and wholesalers.
Business Model & Global Reach
The company applies bulk wholesale pricing with custom quotes based on technical specifications such as thickness, width, and coating type. It maintains experienced global export logistics for North America, Europe, and Russia, offers direct-from-factory custom engineering for specific industrial dimensions and temperature requirements, and provides after-sales technical consultation for fireproof solution design and material selection.
