1. Definition

What is High-Silica Glass Fiber Braided Sleeving? High-Silica Glass Fiber Braided sleeving is a flexible protective sleeving woven from glass fiber yarns with a high silica content (>96% SiO₂). This material offers exceptionally high heat resistance and insulation properties, making it widely used for protecting wires, cables, hoses, and high-temperature pipelines. Its core features are as follows:

Excellent High-Temperature Resistance: Long-term operating temperatures can reach 1000°C, and short-term temperature resistance can exceed 1650°C.

Excellent Electrical Insulation: Stable dielectric properties make it suitable for insulating wires and cables.

Strong Flexibility: The braided structure makes it flexible and bendable, making it easy to install on irregular pipes.

Corrosion Resistance: Resists corrosion from acids, alkalis, and most chemicals.

Asbestos-Free and Environmentally Friendly Material: Complies with environmental and safety standards, ensuring safety and reliability.

2. Advantages

Safety Protection: Effectively protects cables and hoses in high-temperature environments, extending their service life.

Wide Applicability: Suitable for complex working conditions and demanding industries.

Cost-effective: Compared to materials like ceramic fiber, it offers higher mechanical strength and greater flexibility.

3. Application Scenarios

Metallurgy: High-temperature protection for cables and hydraulic hoses.

Power Industry: Insulating conduit for high-temperature environments.

Automotive and Aerospace: Engine compartment wiring harness protection, thermal shielding for aviation pipelines.

Petrochemical: Protective coating for high-temperature fluid hoses and pipes.

4. Selection Guide

Based on Diameter: Select a specification that matches the outer diameter of the cable or pipe.

Based on Temperature Resistance: For high-temperature applications, select sleeving with a high silica content of ≥96%.

Based on Environment: If working with highly corrosive media, confirm the sleeving's chemical resistance.

Installation Method: Flexible braiding is suitable for complex bends and requires fewer fixing points.

5. FAQ

What temperature can high-silica fiberglass sleeving withstand?

It can withstand temperatures of 1000°C (long-term) and up to 1650°C (intermittent).

Is this sleeving conductive? Can it be used to protect wires and cables?

It is non-conductive and has excellent insulation properties, making it commonly used for cable protection in high-temperature environments.

Is it flexible? Can it be installed on curved pipes?

Yes. The braided structure makes it highly flexible, making it ideal for complex bends or irregular pipes.

Is it environmentally friendly?

Yes, it does not contain any harmful substances such as asbestos, meeting environmental standards.

6. Summary

High-silica glass fiber braided sleeving is a high-performance, high-temperature resistant insulation and protective material widely used in power generation, metallurgy, automotive, aerospace, and other fields.
