As a professional manufacturer with over 20 years of experience, Anping County Boli Hardware Wiremesh Products Factory (established in 1998) is proud to present our PTFE Embedded Insulating Sleeve — a high-performance solution designed for demanding electrical insulation applications. With an annual export value of US$5–10 million and a global presence covering North America, Europe, Asia, and beyond, our products are trusted by industries worldwide. This sleeve combines 1000V voltage rating, 260°C continuous temperature resistance, and 0.5mm wall thickness with exceptional dielectric strength, making it an ideal choice for protecting wires, cables, and components in harsh environments.
Our PTFE embedded construction ensures excellent chemical resistance, low friction, and non-stick properties, while the thin 0.5mm wall minimizes space usage without compromising insulation performance. Whether you need to insulate high-voltage wiring in industrial machinery, protect sensors in aerospace systems, or shield cables in automotive engine compartments, this sleeve delivers reliable performance under extreme conditions.
Key Features & Technical Specifications
- High Voltage Withstand: Rated for 1000V AC/DC, providing robust insulation against electrical shocks and arcing.
- Extreme Temperature Resistance: Continuous operating temperature up to 260°C (500°F) with short-term peaks up to 300°C.
- Thin Wall Design: Only 0.5mm thick, allowing for compact assembly and easy routing in tight spaces.
- Superior Dielectric Strength: Typical dielectric strength ≥20 kV/mm, ensuring safety in high-voltage applications.
- Chemical & Environmental Resistance: PTFE material resists almost all chemicals, solvents, oils, and UV radiation, ensuring long service life.
- Low Friction & Non-Stick: Reduces wear on wires and simplifies installation through conduits or harnesses.
- Flame Retardant: Self-extinguishing properties (UL 94 V-0 equivalent) enhance safety in fire-prone areas.
- Customizable Dimensions: Available in various inner diameters (from 1mm to 50mm) and lengths (rolls or cut pieces) to meet your specific requirements.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum continuous working temperature?
A: The sleeve can operate continuously at 260°C, with short-term exposure up to 300°C. It is suitable for high-temperature environments like engine compartments and industrial ovens. -
Q: Can this sleeve be used for outdoor applications?
A: Yes, PTFE is highly resistant to UV radiation, ozone, and moisture, making it suitable for outdoor use. However, we recommend consulting our technical team for specific outdoor conditions. -
Q: Is the sleeve flexible enough for tight bends?
A: The PTFE material is semi-rigid but can be bent smoothly. For applications requiring extremely tight radii, we can adjust the wall thickness or offer a more flexible version upon request. -
Q: What inner diameter and length options are available?
A: Inner diameters can be customized from 1mm to 50mm, and lengths can be supplied in rolls (up to 100m) or cut to your specified lengths. Please provide your requirements. -
Q: Does the sleeve have any certifications?
A: While specific certifications are not listed, our products are manufactured in compliance with international quality standards. We can provide test reports and certifications upon request, depending on your market needs. -
Q: How should I install the sleeve?
A: Simply slide the sleeve over the wire or cable before termination. For larger diameters, a lubricant may be used to ease installation. No heat shrink or special tools are required. -
Q: Can I get a sample before placing a bulk order?
A: Absolutely! We offer free samples (shipping cost may apply) for evaluation. Contact us with your desired dimensions and quantity.
