Core Technology & Products
Advanced Coating Technology Platform
Weidun Composite has developed proprietary expertise across six coating systems: Silicone, Polyurethane (PU), Acrylic, PTFE, EPDM, and Vermiculite. The technical capabilities include base fabric heat resistance up to 550°C (1022°F) for standard E-Glass materials, while specialized high silica fabrics containing over 96% SiO2 withstand continuous exposure to 1100°C (2012°F). This extreme temperature tolerance prevents burn-through in heavy-duty welding and furnace applications where conventional materials fail. Manufacturing flexibility extends to thicknesses ranging from 0.2mm to 6.4mm and custom widths up to 3000mm, utilizing 4HS Satin weave and Twill weave patterns optimized for strength and flexibility.
Silicone Coated Fiberglass Fabric
Positioned as the primary solution for removable insulation covers and expansion joints, this product line addresses degradation challenges caused by UV radiation, moisture infiltration, and chemical exposure. The environmental resilience comes from water-resistant and UV-stable barrier properties that extend thermal insulation system lifespan in outdoor or harsh indoor environments. Available in one-sided or two-sided coating configurations, the fabric maintains coating integrity under continuous high-heat exposure while providing flexible application options for different insulation requirements.
High Silica Fabric
Engineered for extreme temperature barriers in foundries and aerospace applications, this specialized material functions effectively at 1100°C due to its high SiO2 content exceeding 96%. The extreme heat shielding capability makes it essential for preventing component damage in environments where standard fiberglass materials would rapidly degrade.
PTFE Coated Fiberglass Fabric
Designed for non-stick, chemically inert applications in conveyor belts and chemical processing equipment, this product line delivers superior release properties and chemical stability for continuous industrial operations.
Vermiculite Coated Fiberglass Fabric
Specialized for furnace linings requiring enhanced heat dissipation and spark resistance, the vermiculite coating provides additional thermal mass and protective characteristics beyond standard silicone systems.
Industrial Welding Blankets
These protective barriers prevent equipment damage and fire risks in shipyards and metallurgy plants where molten metal spatter and welding sparks pose constant threats. Sewn with high-strength Kevlar or fiberglass thread to ensure structural integrity under thermal stress, the blankets are available in custom sizes from 1x1m up to 3x3m or bespoke dimensions. Multiple material options include silicone-coated or vermiculite-coated versions tailored to different spatter intensities.
Emergency Fire Blankets
Addressing rapid spread of grease fires or clothing fires where water proves ineffective or dangerous, these maintenance-free safety products require no expiry date monitoring and no specialized training to operate. Manufactured with skin-friendly glass fiber fabric that minimizes irritation during handling, the blankets provide non-toxic, eco-friendly protection suitable for food preparation areas in kitchens, hotels, and domestic settings.

Conclusion & Recommendations
Selecting a silicone rubber fiberglass fabric manufacturer requires careful evaluation of technical capabilities, certification compliance, and production scale appropriate to your specific application requirements. For extreme temperature environments exceeding 550°C, verify that manufacturers offer high silica fabric options with documented performance data. When sourcing for regulated industries such as aerospace or nuclear power, prioritize suppliers maintaining ISO 9001:2015 and relevant industry-specific certifications like IATF 16949 or NFPA compliance.
Custom specifications including non-standard widths, specialized coating formulations, or unique weave patterns typically require manufacturers with dedicated R&D capabilities and flexible production lines rather than commodity suppliers. Request material samples with third-party test reports for thermal resistance, tensile strength, and coating adhesion before committing to large volume orders. For international procurement, evaluate manufacturers' export experience and logistics capabilities to ensure reliable delivery schedules and proper documentation for customs clearance.
Consider total cost of ownership beyond initial material pricing, including product lifespan under your operating conditions, maintenance requirements, and potential downtime costs from premature material failure. Manufacturers offering technical consultation services can provide valuable guidance on material selection and system design optimization that may deliver significant long-term savings despite higher upfront costs.
