Teflon Heat Shrink Tube
01
China Fasting Delivery High Quality PVDF Heat Shrink Tube Factory
Product Features
-
◎ Chemical Resistance
Highly resistant to strong acids, alkalis, organic solvents, and oils, with superior stability compared to traditional plastics.
-
◎ Broad Temperature Range
Continuous use from -80°C to 175°C; short-term exposure to higher temperatures possible. High thermal deformation temperature prevents cracking after shrinkage.
-
◎ Mechanical Strength & Wear Resistance
High tensile strength, abrasion-resistant, and anti-cutting, suitable for mechanical transmission parts or high-friction environments.
-
◎ Electrical Insulation
Low dielectric constant and loss, volume resistivity >10¹⁴Ω·cm, ensuring reliable high-frequency signal transmission.
-
◎ Flame Retardancy & Safety
Meets UL VW-1 standard, non-dripping during combustion, with high oxygen index for safety-critical applications.
-
◎ Transparency & Customization
Available in transparent or semi-transparent options for internal component inspection; customizable colors (e.g., black, red, blue) and sizes for identification.
-
◎ Environmental Durability
ROHS compliant, UV-resistant, and maintains structural integrity in harsh conditions.
Application
Product Application
◎ Electronics & Semiconductor: Insulation for high-frequency circuits, solder joint protection, cable labeling.
◎ Industrial & Chemical: Chemical pipeline corrosion resistant, anti-wear for mechanical parts, oil-resistant protection.
Product Application
◎ Medical Devices: Medical-grade products meet USP Class VI standards for sterile equipment insulation and biocompatible applications.
◎ Renewable Energy & Aerospace: Protection for lithium battery modules, high-temperature resistant aviation wiring.
