All about Silicone Coated Fiberglass Cloth

Updated: Nov 5, 2022

Silicone Coated fiberglass fabrics can be used for variety of applications due to the special material properties of Silicone coupled with the strength and thickness of fiberglass.

Silicone cloth can be used for heat resistant clothing, fire blankets, welding splatter protection, weather proof jacketing, conveyor belts for food production, baking trays, bellows and expansion joints.

Silicone is a unique polymer of Silicone (Si) & Oxygen (O2) atoms alongside organic groups giving them the below properties:

Elasticity: Silicone fabrics can have upto 100% elongation at break.

Hydrophobicity: Water does not wet Silicone Coated Fiberglass Cloth.

Temperature Resistance: Silicone Cloth can withstand temperatures between -45 degree Celsius to 250 degree Celsius.

Inherent Flame Resistance: They have an auto-ignition temperature of 430 degree Celsius.

Chemical Resistance: Silicone Coated Fabrics are resistant to organic chemicals , solutions of dilute acids & solvents like ketones, esters & hydrocarbons.

UV Resistant: Silicones resist sun-rays and hence are useful for outdoor jacketing and protection.

Electrical Insulation & Bio-compatibility

Food Contact Grade: Silicone coated fiberglass cloth is available in food contact approved variant.

Silicone Coating on Fiberglass can be done in two ways:

Knife Coating: Used For liquid silicone generally for lower coating weight where the Silicone encapsulates the fiberglass fabric giving more softer fabric of lower thickness.

Calendaring: Dry Silicone is laminated onto fiberglass fabric giving high coating weight pick-up and a fabric which is stronger and thicker upto 5 mm thickness.

what do you think about HR-glass? HR-glass is alkali-free aluminosilicate glass that does not contain boron oxide and fluorine. This glass type could fully substitute E-glass in various aspects. The most important feature of this type of glass is its thermal resistance of up to 800°C.

Advantages of HR glass fibre compared to E-glass:

  • better chemical resistance, particularly in acidic, as well as alkaline and water environments;

  • better thermal resistance;

  • better dielectric properties;

  • equal durability;

  • environmentally friendly glass melting process - does not create dust emissions containing boron oxide.
