The Vulcanized Silicone Fiberglass Cloth is a versatile and essential material across a wide range of industries due to its superior thermal, electrical, and mechanical properties. Its key applications include:

• Manufacturing of Flexible Silicone Heaters:​ It is the fundamental component for creating heater pads and flexible heaters, where the semi-cured layer adheres perfectly to the heating elements (wires or sheets) during vulcanization, forming a highly efficient and durable integrated unit.

• Aerospace Industry:​ Used in components requiring thermal and electrical insulation under fluctuating temperature conditions.

• New Energy Vehicles:​ Protection and insulation in batteries, thermal management systems, and high-voltage wiring.

• Chemical and Petroleum Industry:​ Insulation of equipment and pipelines exposed to corrosive substances and high temperatures.

• Power Generation Equipment:​ Insulation in large generators, transformers, and other high-power electrical components.

• Industrial Machinery:​ Protection of wiring and components in high-temperature and mechanical stress environments.

• Aquaculture:​ Heating and insulation applications in temperature control systems.

• General Electrical Insulation:​ As an insulating barrier in various electrical and electronic configurations.

• Construction:​ Flame-retardant and insulating material in specific applications.

Our Vulcanized Silicone Fiberglass Cloth stands out due to a series of features and advantages that position it as a leader in its category:

• Flame-Retardant Properties:​ Acts as a coated flame-retardant blanket/fabric, providing an additional layer of safety by not propagating flames.

• High Mechanical Strength and Flexibility:​ Combines the robustness of fiberglass with the elasticity of silicone, resulting in a high-strength material that is both soft and tough, allowing for easy cutting and processing.

• Optimal Adhesion:​ The semi-cured side allows for a strong and durable bond with other materials during hot vulcanization, crucial for manufacturing integrated components.

• Environmental Compliance:​ Halogen-free and compliant with RoHS standards, ensuring a safe and environmentally friendly product.

• Format Versatility:​ Available in various thicknesses, widths, and lengths, with customization options for specific requirements.

Vulcanization Process for Flexible Silicone Heaters

The Vulcanized Silicone Fiberglass Cloth (semi-cured) is fundamental in the manufacturing of flexible silicone heaters. The hot vulcanization process is critical to ensuring optimal bonding and durable performance. The step-by-step method is detailed below:

1. Material Preparation:​ Ensure you have the Silicone Fiberglass Fabric sheets cut to the desired size, the heating elements (heater wires or sheets), and a hydraulic press with temperature and pressure control.

2. Component Alignment:​ Place the first sheet of Fiberglass with Silicone Coating (with the semi-cured side facing up) onto a clean surface. Carefully arrange the heating elements on this sheet. Then, place the second sheet of Vulcanized Fiberglass Cloth (with the semi-cured side facing down) over the heating elements, ensuring precise alignment.

3. Gradual Application:​ When joining the two silicone sheets, avoid pressing them together all at once. Instead, apply them while exerting gradual and uniform pressure to prevent air bubbles or wrinkles from forming.

4. Press Preparation:​ Once the assembly is aligned, carefully place it into the hydraulic press. It is critical to place a foamed silicone pad between the press surfaces and the heater assembly. This pad provides the necessary cushioning to distribute pressure evenly; without it, pressure may be uneven, and the final product will not form correctly.

5. Vulcanization Configuration:​ Configure the hydraulic press with the following parameters:

   • Temperature:​ 165°C

   • Time:​ 3 minutes

   • Pressure:​ Pressure must be calibrated so that after compression, a slight overflow of silicone material is observed on both sides of the assembly. This indicates that the optimal pressure for effective vulcanization and bonding has been reached.

6. Vulcanization Process:​ Activate the press and maintain the specified temperature and pressure for 3 minutes. During this time, the semi-cured silicone will fully vulcanize, creating a strong, integrated bond with the heating elements and the other silicone layer.

7. Cooling and Demolding:​ Once the vulcanization cycle is complete, remove the assembly from the press and allow it to cool completely before handling. This ensures dimensional stability and the integrity of the final product.
