Silicone Fabric Production Process

Silicone coated (impregnated) fiberglass fabrics are made of fiberglass basic fabrics coated, impregnated or calendered with 

specially compounded silicone rubber on one or both sides. 


Heaterk's silicone coated fiberglass fabric, using E-Glass fiberglass fabric, one or both sides with silicone rubber coating, is resistant to high temperatures. The fiberglass base fabric provides it with mechanical strength. Silicone coating protects sparks and metal splashes generated by welding, making the entire fabric impenetrable to any liquid, gas, smoke, or light. Its flame retardant and heat resistant properties are permanent and can withstand temperatures of 230℃ in continuous and 550℃ in peak operation.



It has a lot of advantages such as high strength, fire retardant, high 

temp. resistance, chemical resistance, none-penetrative, non-toxic and so on. It could be used in temperature from-70°C/-94°F to 




Silicone coated glass cloth is widely used for heat protection and spark protection of objects, surfaces, and areas. Heaterk recommends vertical use, such as curtains; try always to place the silicone side on the exposed site. The flexibility of this fabric can be perfectly adapted to any surface that needs protection, such as metal structures, boiler manufacturing installations, pipes, removable insulation jackets, etc.

Lightweight silicone Fabric

0.2~0.7mm and 0.8mm (single-sided coating) thickness of single-sided and double-sided silicone impregnated fabric, used as high-temperature curtains and barrierswelded slats and heat-resistant sleeves and jackets, rain or spray protection / Rinse high-temperature cloth for making waterproof caps, sleeves, jackets.

Medium silicone rubber coated glass fabric

0.8mm double-sided silicone rubber coated glass fabric is an excellent welding spatter safety , and soft melting metal spatter; it also includes a double-sided coating on very versatile filament fabric. Good weld spatter protection for use as a cold side shield in engine and generator exhaust insulation blanket systems.

Heavy duty silicone coated glass cloth

Silicone rubber coated fabric above 0.8mm is highly durable, usually manufactured in strips, stripes, or otherwise, to protect hosescables, and machinery from extreme industrial conditions. The heaviest heat management fabric on the market, best suited for heavy-duty melt spatter and slag applications.


Heaterk silicone rubber fabrics were certified in 2020 by the UL 94 test (Standard for plastics flammability) with a V0 classification. In 2021, this fabric also participated in ASTM E84 (Standard Test Method for Surface Burning Behavior of Building Materials) with a Class A classification. It also complies with Class 1 classification according to EN ISO 9185 - Behavior of materials under the influence of small molten metal splashes.

I'm using it to make a bullet smoker smoking blanket and it works just fine. It’s just that the freight is very expensive. For 4,000 square meters of fabric, it cost 830 US dollars by air.

Very fast

This is very effective for partially covering a thick piece of material during preheating and welding with 9018. It's relatively light. The silver silicone coating does an excellent job of catching weld spatter. It looks durable, but time will tell. I'm thankful there's no fibreglass coming off everywhere like a cheap blanket.
