Silicone Rubber Coated Fiberglass Sleeving: For High-Temperature, High-Insulation Applications

In the power, electronics, and industrial sectors, the safe and stable operation of equipment depends on the use of high-performance insulation materials. Silicone rubber coated fiberglass sleeving, widely used in high-temperature, high-voltage environments, has become the preferred choice of many engineers and businesses.

What is silicone rubber coated fiberglass sleeving?

Silicone rubber coated fiberglass sleeving is a flexible insulating sleeve constructed from a high-strength alkali-free glass fiber braided tubing inner lining and coated with high-quality silicone rubber, cured through a special curing process. Its structure combines the mechanical toughness of glass fiber with the excellent electrical insulation and temperature adaptability of silicone rubber, maintaining stable performance over a wide temperature range of -60°C to 200°C.

Core Performance Advantages

1. Excellent Insulation Performance

Fiberglass sleeving has extremely high dielectric strength, effectively isolating current, preventing leakage and short circuits, and providing reliable protection for critical components such as wiring harnesses and terminals in high-voltage circuits.

2. Excellent High-Temperature Resistance

Silicone rubber coated fiberglass sleeving can operate in environments as high as 200°C for extended periods and can even withstand higher temperatures for short periods. It offers strong thermal stability and is resistant to melting, aging, or deformation, making it suitable for use around heating components and in high-temperature environments.

3. Excellent Chemical and Mechanical Properties

It is resistant to acids, alkalis, moisture, and ozone, while maintaining flexibility and tear resistance, making it easy to install and route, and providing long-lasting protection in complex industrial environments.

Main Applications Of Silicone Fiberglass Sleeving

Due to its performance characteristics, silicone rubber-coated fiberglass sleeve is widely used in the following applications:

• Household Appliances and Electrical Equipment: Insulation and protection of internal wiring harnesses in heating appliances such as electric ovens, heaters, and microwave ovens;

• Industrial Motors and Transformers: As an Insulation sleeve for motor windings and transformer lead wires, enhancing equipment safety;

• New Energy Vehicles: Insulation and flame retardancy in battery packs, electronic control systems, and charging equipment;

• Aerospace and Rail Transit: Suitable for applications requiring extremely high flame retardancy, temperature resistance, and reliability;

• Lighting Industry: Internal insulation treatment for high-temperature lighting equipment such as LED drivers and metal halide lamps.

Choosing silicone rubber coated fiberglass sleeving is more than just a choice of material. Its long-term high-temperature resistance and high dielectric strength significantly reduce the risk of failure due to insulation failure, extending equipment life and reducing maintenance frequency and costs. This product is undoubtedly an ideal choice for users who demand high reliability and safety standards.
