Calcium silicate coated fiberglass fabric is a specialized type of fabric that is commonly used in high-temperature applications. It consists of a woven fiberglass substrate that is coated or impregnated with a layer of calcium silicate.
Here are the key features and characteristics of calcium silicate coated fiberglass fabric:
Heat Resistance: The primary purpose of the calcium silicate coating is to enhance the fabric’s heat resistance. Calcium silicate is a highly refractory material that can withstand high temperatures without significant degradation. It has a remarkable capability to withstand short-term exposures up to 650°C, providing exceptional high temperature performance. In addition, the fabric is engineered for long-term use in high temperature environments. It maintains its integrity and functionality with a work temperature of 400°C, ensuring durability and reliability.
Fire Resistance: The coating also provides the fabric with excellent fire resistance. It is non-combustible and can act as a barrier to prevent the spread of flames. This property makes calcium silicate coated fiberglass fabric suitable for applications that require fireproofing or heat insulation.
Insulation Properties: Calcium silicate has low thermal conductivity, which means it can effectively insulate against heat transfer. The fabric’s insulation properties make it useful for applications where temperature control is crucial, such as in thermal insulation jackets, fire barriers, removable insulation covers, and expansion joint seals.
Chemical Resistance: Calcium silicate coated fiberglass fabric is resistant to most chemicals, acids, and alkalis. It can withstand exposure to various industrial chemicals without significant degradation, making it suitable for applications in corrosive environments.
Flexible and Durable: The fiberglass substrate provides the fabric with flexibility and durability. It can be easily cut and fabricated into different shapes and sizes to fit specific applications. The fiberglass reinforcement also increases the fabric’s mechanical strength and tear resistance.
Thermal Stability: Calcium silicate exhibits excellent thermal stability, even under extreme temperature conditions. It does not shrink, melt, or produce toxic fumes when exposed to high heat.
Applications of calcium silicate coated fiberglass fabric include:
Insulation covers and jackets for pipes, valves, boilers, and other industrial equipment.
Fireproof curtains and barriers.
Expansion joint seals in high-temperature environments.
Protective clothing and gloves for workers in heat-intensive industries.
Gaskets and seals in automotive and aerospace applications.
Thermal insulation in furnaces and kilns.
Insulation for fire doors and walls.
It is important to note that the specific properties and applications of calcium silicate coated fiberglass fabric can vary depending on the manufacturer and the precise formulation of the coating. It is recommended to consult with fabric suppliers or manufacturers for detailed information on product specifications and suitability for specific applications.
