Heat Shrink Tube
01
Excellent oil resistance Fluorine Rubber Heat Shrink tubing factory in China
Product Features
-
◎ High-Temperature Resistance
• Operating temperature range: -55°C to 200°C (short-term exposure up to 220°C).
• Shrinkage temperature: starts at 150°C, fully shrinks at 175°C. -
◎ Chemical & Oil Resistance
• Resistant to fuel, lubricating oil, hydraulic fluid, and organic solvents; ideal for engine compartments, fuel tanks, and hydraulic systems.
-
◎ Mechanical & Electrical Properties
• Shrink ratio: 2:1 (radial shrinkage 50%, axial shrinkage <20%).
• Tensile strength: 10.5 N/mm², elongation 300%, ensuring flexibility and tear resistance.
• Insulation: Volume resistivity >10¹⁴ Ω·cm, dielectric strength ≥26 kV/mm, meeting electrical safety standards. -
◎ Environmental & Safety Compliance
• Compliant with ROHS, REACH, and Sony SS-00259 environmental directives; free from halogens, PBDEs, and other hazardous substances.
• Flame retardancy: UL94 V-0 rated, self-extinguishing within 15 seconds, suitable for high-safety environments.

Usage Instructions
-
◎ Installation
• Slide tubing over the component to be protected, ensuring full coverage.
• Apply heat (e.g., heat gun or oven) at 175°C until fully shrunk and conformal.
• After cooling, verify sealing and insulation integrity. -
◎ Cautions
• Avoid excessive heating to prevent material degradation.
• Store in dry conditions; avoid prolonged UV exposure.
