Function
The Silicone Fiberglass Sleeving serves as a high-temperature electrical insulation and mechanical protection cover.
Its dual-layer structure — flexible fiberglass braiding and silicone coating — provides both thermal endurance and resistance to voltage, oil, and aging.
It is mainly used to:
Insulate electrical conductors and wires
Protect cables from heat, abrasion, and chemical corrosion
Bundle and organize wiring in electrical systems
Advantages of Use
High Temperature Resistance:
Withstands continuous exposure to 200°C and brief peaks up to 250°C — ideal for high-heat environments.
Excellent Electrical Insulation:
Ensures safety and stability in motor and transformer wiring applications.
Durable and Flexible:
Resists tearing, aging, and moisture while remaining easy to bend and install.
Flame Retardant & Safe:
Self-extinguishing silicone coating provides added protection against fire hazards.
Chemical and Oil Resistance:
Performs reliably even in harsh industrial environments with oils, solvents, and coolants.
Applications
The High Temperature Fiberglass Sleeving is widely applied in:
Electric motors and transformers
Household appliances and lighting equipment
Automotive wiring harnesses
Aerospace and marine industries
Electronic components and circuit boards
This sleeving provides a long-term insulation solution for demanding applications requiring heat, flame, and abrasion protection.
How to Use
Cut the sleeving to the desired length.
Slide it over the wire or cable to cover the area requiring protection.
Secure both ends with heat shrink tubing or insulating tape if necessary.
Avoid excessive stretching to maintain insulation integrity.
Maintenance & Storage
Store in a dry, ventilated environment, away from direct sunlight.
Avoid contact with acids, alkalis, or solvents for prolonged periods.
Periodically inspect for cracks or hardening after long-term exposure to heat.
FAQ
Q1: What temperature can Silicone Fiber Glass Sleeving withstand?
A1: It can operate continuously at 200°C and short-term at 250°C without losing insulation performance.
Q2: Can I get custom diameters or colors?
A2: Yes. We provide OEM customization in size, color, and printing upon request.
Q3: Is it suitable for automotive or aerospace use?
A3: Absolutely. Its high temperature and flame-retardant properties make it perfect for harsh environments.
Q4: What’s the difference between Fiberglass Sleeving and Silicone Coated Fiberglass Sleeving?
A4: Pure Fiberglass Sleeving is uncoated and mainly used for general insulation, while Silicone Fiber Glass Sleeving adds a silicone layer for enhanced heat, flame, and moisture resistance.
Q5: Do you provide samples or technical data sheets?
A5: Yes, samples and full specifications are available upon request.
