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).
