Teflon Heat Shrink Tube
01
Newly developed self-developed high-end PTFE heat shrink tubing with unique formula
Product Features
-
◎ Broad Temperature Range
Continuous use from -80°C to 260°C; short-term exposure to higher temperatures possible. Shrinkage requires >300°C for tight encapsulation.
-
◎ Chemical Stability
Resistant to strong acids, alkalis, organic solvents, and oils; only elemental fluorine and molten alkali metals may affect it at high temperatures.
-
◎ Electrical Insulation
Stable dielectric constant (2.1), surface resistance >10¹³Ω, volume resistance >10¹⁸Ω·m, ensuring reliable high-frequency signal transmission.
-
◎ Low Friction & Non-Stick
Dynamic friction coefficient 0.2-0.3, hydrophobic surface (contact angle 114°), preventing media adhesion.
-
◎ Flame Retardancy & Safety
Meets UL94 V-0 standard, oxygen index >95%, non-combustible in air.
-
◎ Mechanical Performance
Shrink ratio 1.7:1 or 4:1 (model-dependent), tightly conforms to substrates after shrinkage, providing stress relief and sealing.
-
◎ Environmental Durability
ROHS compliant; lifespan 5-8 years in normal conditions, maintains integrity in harsh environments.
Application
Product Application
◎ Electronics: Insulation for high-frequency circuits, solder joint protection, cable labeling.
◎ Industrial: Chemical pipeline anti-corrosion, anti-wear for mechanical transmission parts.
Product Application
◎ Medical: Biocompatible certified products for sterile equipment.
◎ Aerospace: High-temperature protection for aviation wiring.
