High-Temperature Resistant FEP Heat Shrink Tubing - Reliable Supplier & Factory in China
Product Features
-
Ultra-Wide Temperature Range
• Continuous use from -80°C to 200°C; short-term exposure to higher temperatures (e.g., 300°C instantaneous contact) possible.
• High thermal deformation temperature prevents cracking after shrinkage, suitable for high-temperature welding joint protection and extreme temperature cycling. -
Superior Chemical Stability
• Resistant to strong acids (e.g., sulfuric acid, hydrochloric acid), alkalis (e.g., sodium hydroxide), organic solvents (e.g., acetone, xylene), and oils.
• Reacts only with elemental fluorine and molten alkali metals (e.g., sodium, potassium) at high temperatures, with chemical inertness surpassing traditional plastics. -
Excellent Electrical Insulation
• Stable dielectric constant (2.1), consistent across 60Hz–60MHz frequency range, ensuring reliable high-frequency signal transmission.
• Volume resistivity >10¹⁸Ω·m, surface resistance >10¹³Ω, arc resistance >165 seconds, with no conductive channel formation after damage. -
Low Friction & Non-Stick Properties
• Dynamic friction coefficient 0.2–0.3, hydrophobic surface (contact angle 114°), preventing media adhesion and facilitating cleaning.
• Non-stick characteristics make it suitable for coating transmission rollers and food processing equipment requiring contamination prevention. -
High Transparency & Visibility
• Transparent material allows clear inspection of internal components, aiding in solder point verification, circuit identification, and medium flow monitoring.
• Low refractive index ensures outstanding transparency among plastics, ideal for applications requiring aesthetic appearance. -
Flame Retardancy & Safety
• Meets UL94 V-0 standard, oxygen index >95%, non-combustible in air, and produces no dripping during combustion.
• Suitable for safety-critical applications, such as medical devices and aerospace wiring. -
Mechanical Strength & Wear Resistance
• High tensile strength, abrasion-resistant, and anti-cutting, suitable for mechanical transmission parts or high-friction environments.
• Shrink ratio 1.25:1 or 1.3:1 (model-dependent), tightly conforms to substrates after shrinkage, providing stress relief and sealing. -
Environmental Durability
• ROHS compliant, UV-resistant, and maintains structural integrity in harsh environments.
• Lifespan 5–8 years in normal conditions, with slow performance degradation in extreme environments (e.g., chemical corrosion, high temperature).
