When you choose silicone coated fiberglass fabric, you may see the option of Silicone And AL Coated Fiberglass Fabric, which is a special fabric that is modified on the basis of silicone coated fiberglass fabric. Let's take a look at this fabric and learn the applications of it.

What is Silicone and AL Coated Fiberglass Fabric?

Silicone and AL (aluminum) coated fiberglass fabric is a specialized type of fabric that combines the properties of both silicone-coated fiberglass fabric and aluminum-coated fabric. This composite material is created by applying a layer of silicone and a layer of aluminum coating to a base layer of fiberglass fabric.

The aluminum coating adds a reflective surface to the original properties of silicone fiberglass cloth. Silicone and AL coated fiberglass fabric are commonly used in applications where both high-temperature resistance and reflectivity are required. Some typical applications include Heat Shields, Thermal Insulation, Fire Barriers, Welding Protection, Oven and Kiln Insulation, etc.

What is Silicone Coated Fiberglass Sleeve？

Silicone Coated Fiberglass Sleeve, sometimes referred to as a Silicone Coated Fiberglass Tubing or simply a Silicone Sleeve, is a specialized protective covering made from a combination of fiberglass and silicone materials.

Silicone coated fiberglass sleeves are commonly used in a range of industrial scenarios where protection against high temperatures, abrasion, and chemical exposure is required. Typical applications include insulating and protecting electrical wires, cables, and components in the electrical and electronics industry, serving as thermal insulation and fire protection in automotive and aerospace settings, and safeguarding hoses and machinery components from harsh environments in industrial manufacturing.

Silicone Fiberglass Fabric with One Side Coated VS with Two Sides Coated

One side coated

Silicone fiberglass fabric with one side coated is utilized in various applications where selective protection is required.

For instance, when designing protective covers for machinery, this kind of fabric offers resistance to heat, flames, or abrasion on the coated side, while the uncoated side can safely interact with the equipment without added protection. In wire and cable insulation, the coated side provides heat and flame resistance, ensuring safety, while the interior side doesn't need the same level of protection.

Two side coated

Silicone fiberglass fabric with two sides coated finds relevance in various applications, including fire blankets, flame-resistant curtains, automotive heat shields, protective covers, expansion joints, and hose or cable protection. In these situations, uniform protection on both sides of the material is required to ensure that it can effectively withstand high temperatures, flames, abrasion, and potential exposure to chemicals or contaminants.

For instance, fire blankets must provide equal protection on both sides to smother fires and shield against heat and flames, while expansion joints in construction need to accommodate structural movement and offer consistent insulation and weather resistance. This kind of fabric is chosen to guarantee reliable and balanced protection in such demanding environments.
