Silicone Heat Shrink Tube
01
China Professional Bright Silicone Heat Shrink Tube Factory
Features
-
◎ Enhanced Softness and Strength
Operating from -60°C to 200°C, it withstands prolonged exposure to high-temperature baking, freezing, and rapid thermal cycling, preventing material tendering or deformation. Ideal for automotive engine compartments and industrial ovens.
-
◎ Superior Flexibility & Sealing
The silicone material ensures high elasticity, allowing the tubing to shrink tightly around cables and form a seamless seal against moisture, dust, and chemical gases. Its tear resistance surpasses standard heat shrink tubing, resisting mechanical bending and vibration-induced cracking.
-
◎ High Insulation & Dielectric Performance
With a dielectric strength exceeding 20kV/mm, it provides reliable insulation for high-voltage cables, preventing leakage and arcing. Low dielectric constant and loss tangent (tanδ) make it suitable for high-frequency signal transmission, minimizing signal attenuation.
-
◎ Environmental & Safety Compliance
RoHS and REACH compliant, free from halogens and phthalates. Low smoke and halogen-free upon combustion, ensuring safety in aerospace and rail transit applications. UL 94 V-0 flame retardant certified.

Application
Product Application
Glossy silicone heat shrink tubing is widely used in demanding sectors due to its heat resistance, flexibility, and environmental safety. In electronics, it safeguards PCBs, sensors, and connectors from mechanical damage and EMI. For automotive applications, it protects battery packs, wiring harnesses, and engine components against oil and vibration. In renewable energy, it resists UV rays and outdoor conditions for solar inverters and wind turbines.
Product Application
Medical devices benefit from its biocompatibility, ensuring sterile cable protection. Home appliances like coffee machines and microwaves rely on its insulation and sealing. Aerospace applications utilize its extreme temperature tolerance for aircraft wiring. The glossy surface aids cleaning and maintenance, ideal for automated production lines.
