Product Introduction: Silicone-Coated Glass Fiber Fabric (Specialized for Insulation Jackets)

I. Shortcomings of Conventional Silicone-Coated Glass Fiber Cloth

Common silicone-coated Glass Fiber Fabrics on the market are only suitable for mild, non-corrosive working conditions:Their acid and alkali resistance is limited to only 15% concentration of weak acids and alkalis. When exposed to higher-concentration acid/alkali media or vapors, the molecular structure inside the silicone coating is eroded and damaged, causing surface stickiness and softening, followed by gradual powdering, peeling, and cracking of the coating.

Additionally, conventional silicone has mediocre heat resistance. It tends to age and deteriorate with prolonged high-temperature use. When used as the surface material for equipment insulation jackets, it has a short service life, and its thermal protection performance degrades rapidly.

II. Core Advantages of Suzhou Weidun High-Performance Silicone-Coated Glass Fiber Cloth

With 20 years of in-depth experience in composite glass fiber materials, our factory has built a professional R&D team including foreign technical experts. We independently developed a custom acid and alkali-resistant modified silicone formula, specifically for the production of insulation jackets for chemical and thermal pipelines.

1. Superior Acid & Alkali Resistance, Stable Even in 32% High-Concentration SolutionsThe formula incorporates special anti-corrosion barrier fillers and a high-density crosslinking system, resulting in a dense, pinhole-free silicone coating that forms an impermeable protective layer against acid and alkali media. After immersion in 32% acid/alkali solution, the fabric shows no stickiness, softening, or peeling, ensuring stable coating performance.

2. Excellent High-Temperature Resistance, Ideal for High-Heat Insulation ApplicationsThe modified organic silicone resin has upgraded heat resistance. It can withstand long-term continuous use at temperatures of 200–280°C and can withstand instantaneous temperatures up to 500°C. It resists cracking and powdering in high-temperature environments, ensuring long-lasting and stable thermal insulation performance.

3. Tailored for All Scenarios of Insulation Jacket ApplicationsDeveloped specifically for the complex conditions of insulation jackets for chemical pipelines, thermal equipment, and industrial tanks, the material balances multiple properties including high-temperature resistance, acid/alkali corrosion resistance, aging resistance, and excellent flexibility. It is highly durable, significantly extending the overall service life of the insulation jacket.

III. Summary of Core Advantages

Conventional silicone cloth uses a generic base formula with no anti-corrosion modification, meaning it fails easily even in low-concentration acid/alkali environments. In contrast, Suzhou Weidun’s self-developed acid/alkali-modified silicone system, combined with mature coating technology and years of industry R&D experience, can stably resist erosion from 32% high-concentration acids and alkalis. It is also high-temperature resistant and anti-aging, making it a high-quality supporting raw material specifically designed for industrial insulation jackets. Custom specifications and thicknesses are available to meet the working condition requirements of various customers.
