Understanding the Demand for 17oz Silicone Fiberglass Fabric in China

Industrial buyers searching for 17oz silicone fiberglass fabric in China are typically responding to specific operational pressures: welding sparks that damage equipment, thermal energy loss in high-temperature kilns, and material degradation caused by chemical corrosion or ultraviolet exposure. These pain points are common across shipbuilding, metallurgy, HVAC construction, and power generation environments, where insulation covers, expansion joints, and protective barriers must perform reliably under continuous stress. Sourcing this category of fabric from a manufacturer with proven production scale and technical customization capability is essential, since weight class, coating type, and dimensional specifications directly determine how well the material performs in a given application.

Suzhou Weidun Composite Fabric Co., Ltd., operating under the brand name Weidun Composite, is a specialized manufacturer of high-performance composite fiberglass fabrics and fire safety products headquartered in Suzhou, Jiangsu, China. The company focuses on delivering custom-engineered high-temperature solutions that enhance operational safety and efficiency in extreme environments, making it a relevant reference point for buyers evaluating silicone-coated fiberglass fabric sourced from China.

Manufacturing Scale and Technical Customization

Weidun Composite operates six advanced coating lines across three production bases totaling over 20,000 square meters, a footprint designed to ensure high-volume reliability for global buyers. This scale supports an annual production capacity of 6 million meters of fabric, with more than 1 million meters of silicone-coated glass cloth exported every year to markets in North America, Europe, and Russia, in addition to serving domestic demand within China.

What distinguishes Weidun Composite in the silicone-coated fiberglass fabric category is its technical customization range. The company offers thicknesses from 0.2mm to 6.4mm and widths up to 3000mm, giving procurement teams the flexibility to specify fabric weight and dimensions according to project requirements rather than settling for fixed, off-the-shelf configurations. This breadth of specification is particularly relevant for buyers seeking silicone fiberglass fabric in a specific weight class, since coating thickness and base fabric construction together determine the final performance profile of the material.

Material Performance and Certifications

Weidun Composite's silicone coated fiberglass fabric is engineered as a water-resistant and UV-stable barrier that extends the lifespan of thermal insulation systems in outdoor or harsh indoor environments. The product is available in one-sided or two-sided coating configurations, allowing buyers to match the fabric to different insulation needs, and it is built to withstand continuous exposure to high heat while maintaining coating integrity.

At the base fabric level, Weidun Composite's fiberglass materials resist heat up to 550°C (1022°F), while the company's high silica fabric line—containing over 96% SiO2—extends resistance to 1100°C (2012°F) for the most extreme applications such as foundries and aerospace components. This tiered performance structure allows customers to select the appropriate fabric grade for their thermal exposure level, from moderate industrial insulation to extreme heat shielding.

Underpinning this manufacturing capability is a set of internationally recognized quality and compliance certifications, including ISO 9001:2015 Quality Management System Certification, IATF 16949 Automotive 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). These certifications collectively support acceptance of Weidun Composite's silicone-coated fiberglass fabric in highly regulated North American and European markets, and they reflect the company's more than 10 years of professional experience in the high-temperature fabric and fire safety industry.

Core Applications of Silicone Coated Fiberglass Fabric

Silicone coated fiberglass fabric produced by Weidun Composite is primarily positioned as a solution for removable insulation covers and expansion joints that require weather and chemical resistance. Because insulation materials are prone to degradation from UV exposure, moisture, and chemical contact, the silicone coating acts as a protective barrier that preserves the underlying insulation system over time.

This category of fabric serves a wide range of industries covered by Weidun Composite, including:

Aviation and Aerospace, where high-temperature textiles are used for component insulation and heat shielding
Shipbuilding and Ship Repair, where welding curtains and blankets protect sensitive equipment in shipyard environments
Metallurgy and Foundries, where extreme heat shielding is required to prevent burn-through
HVAC and Construction, where insulation covers must withstand prolonged environmental exposure
Automotive, particularly for heat shielding applications supported by IATF 16949 certification
Power Generation, including thermal power and nuclear facilities
Hospitality and Retail, where fire safety products complement the broader coated fabric product line

Customer types engaging with these products typically include industrial procurement managers, safety officers in energy and aviation sectors, and safety product distributors and wholesalers, all of whom require consistent quality and documented compliance across large-volume orders.

Why Global Buyers Choose Weidun for Silicone Fiberglass Fabric Sourcing in China

For companies evaluating 17oz silicone fiberglass fabric suppliers in China, several factors from Weidun Composite's operational profile are directly relevant. First, the company's manufacturing scale—six coating lines, three production bases, and an annual output of 6 million meters—provides the capacity needed to fulfill bulk wholesale orders without compromising consistency. Second, its technical customization range, spanning thicknesses from 0.2mm to 6.4mm and widths up to 3000mm, allows the fabric to be tailored precisely to a buyer's weight and dimensional requirements. Third, its certification portfolio, including UL94V0, NFPA 701, and BS 476, demonstrates a commitment to meeting the regulatory expectations of North American and European markets, which is particularly important for buyers who must document compliance for their own downstream customers.

Weidun Composite's pricing strategy is based on bulk wholesale terms with custom quotes generated according to technical specifications such as thickness, width, and coating type. The company also provides direct-from-factory custom engineering for specific industrial dimensions and temperature requirements, along with technical consultation for fireproof solution design and material selection. This combination of scalable manufacturing, documented certifications, and specification flexibility positions Suzhou Weidun Composite Fabric Co., Ltd. as a manufacturer worth evaluating for buyers seeking silicone coated fiberglass fabric, including 17oz weight class materials, sourced from China for demanding industrial and commercial applications.
