Overview

PTFE tube (polytetrafluoroethylene tube), also known as Teflon tube, is made from suspended polymerized PTFE resin through molding and high-temperature sintering. This unique production method ensures the tubing has excellent physical stability, superior chemical resistance, and reliable performance even under harsh working conditions.

Features

• Manufactured by molding process using high-purity suspended PTFE resin

• Exceptional chemical resistance against strong acids, alkalis, and organic solvents

• Excellent electrical insulation performance suitable for high-frequency applications

• Very low friction coefficient, ensuring smooth surface and strong anti-adhesion properties

• Wide temperature resistance range, maintaining performance from -200°C to +260°C

• Non-toxic and non-aging, making it ideal for clean or high-purity environments

Applications

PTFE tubes are widely used across multiple industries, including:

• Electrical and electronic industry: wire and cable insulation sleeves, high-frequency insulation parts

• Chemical and pharmaceutical industry: corrosion-resistant fluid pipelines and containers

• Mechanical and industrial systems: seals, bearings, and non-stick parts under extreme conditions

• Aerospace and automotive sectors: fluid and gas transmission in high-temperature environments

Technical Specifications

Conclusion

With its excellent chemical stability, dielectric strength, and wide temperature tolerance, PTFE tube is one of the most versatile engineering plastics in the world.
It is the preferred material for insulation, corrosion-resistant pipelines, and precision industrial components that demand safety, reliability, and durability.
