☆FEP Teflon Heat Shrink Tubing Features:

August 27, 2018

☆FEP Teflon Heat Shrink Tubing Features:

◆ 1. FEP pipe is made of imported PTFE, with high temperature resistance and corrosion resistance. It can be used to transport gas, water, acid, alkali and most chemical solvents.

◆ 2, temperature: -60 °C to 200 °C.

◆ 3, working pressure: 15kg/cm2

◆ 4. Note that the larger the pipe diameter, the smaller the working pressure.

☆ Product Application:

Aerospace Transportation Technology, Electronics, Components & Insulators, Chemicals & Pharmaceuticals, Food Processing, Environmental Sciences, Air Sampling, Fluid Handling Equipment, Water Treatment Systems


PTFE Teflon heat shrinkable tube uses Shrinkage temperature: 300°C~340°C, non-adhesive, fight against water, contact angle of oil and water θ=114,
Does not burn in non-flammable air (Oxygen Index >95VOL%)
Corrosion resistance

Only at high temperature, elemental fluorine and alkali metal work with it, and it has no effect on the reliability and high insulation of all other concentrated and dilute inorganic organic acids, bases and esters.
The dielectric constant of 60HZ-60MHZ is 2.1 at high and low temperatures. Even if the surface is damaged by diving, no conductive track will be produced. Volume resistance>1018ΩM, surface resistance>1013Ω, arc resistance>165 seconds without leakage, low friction, dynamic friction coefficient 0.2-0.3

Shrink ratio: 1.8:1

Continuous use temperature: -55~260°C
Teflon heat shrinkable tube: Rated voltage (Rated voltange): 300/600V, Test voltage (Testing voltange): 2500V, Rated temperature: -80°C to 280°C. Teflon shrink sleeves have high temperature resistance, corrosion resistance, and good mechanical strength. Widely used in electronics, computers, chemicals, electric heating, aerospace, military, communications and other important science and technology industries.
