High-Quality China Silicone Heat Shrink Tubing from Leading Suppliers and Factory for Superior Performance
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.

Frequently Asked Questions
The glossy silicone heat shrink tubing operates reliably from -60°C to 200°C. It withstands prolonged exposure to high-temperature baking, freezing, and rapid thermal cycling without tendering or deformation, making it ideal for automotive engine compartments and industrial ovens.
The silicone heat shrink tubing is available in two shrink ratios: 1.7 Times and 2 Times. Both types come in a wide range of specifications from 1.0mm to 220mm inner diameter, with various wall thicknesses to suit different application requirements.
Yes. The tubing is fully RoHS and REACH compliant, free from halogens and phthalates. It produces low smoke and is halogen-free upon combustion. It is also UL 94 V-0 flame retardant certified, ensuring suitability for aerospace, rail transit, and other safety-critical applications.
The tubing is widely used across multiple industries including electronics (PCBs, sensors, connectors), automotive (battery packs, wiring harnesses, engine components), renewable energy (solar inverters, wind turbines), medical devices, home appliances, and aerospace (aircraft wiring). Its glossy surface also makes it ideal for automated production lines.
The tubing has a dielectric strength exceeding 20 kV/mm, providing reliable insulation for high-voltage cables and preventing leakage and arcing. Its low dielectric constant and loss tangent (tanδ) also make it suitable for high-frequency signal transmission, minimizing signal attenuation.
MOQ and packaging vary by specification. Smaller diameter sizes (e.g., 1.0–5.5mm) typically have an MOQ of 1200M–2000M with packing in 200M rolls. Larger diameter sizes (e.g., 90mm and above) are packed in 1M-Bar units with MOQ starting from 75M–100M. Please refer to the specification sheets above or contact us for custom requirements.
