Silicone Heat Shrink Tube
Description
Technical Parameters
Silicone Heat Shrink Tube
Our silicone heat shrink tube is widely used across industrial electronics, automotive wiring and new‑energy projects. Made from cross‑linked silicone rubber, this sleeve delivers reliable insulation and physical protection for cables, connectors and sensitive components.
When heated, the tubing shrinks firmly around parts to form a tight protective barrier. It holds up well in extreme hot‑cold conditions, and stands against ozone, UV exposure and common industrial chemicals. We work with distributors, project buyers and OEM partners, and can adjust sizes, colors and markings to match your project requirements.
Extreme Temperature Resistance & Stable Performance
The silicone heat shrink sleeve supports a wide operating temperature range of -60°C to 200°C, maintaining soft elasticity and structural stability in long-term high-temperature environments without deformation, cracking or performance attenuation. It can resist instantaneous high-temperature impact, perfectly adapting to harsh working conditions such as engine compartments, industrial high-temperature workshops and outdoor high-temperature exposure, far exceeding the temperature resistance limit of ordinary PVC and PE heat shrink tubes.
Precise Heat Shrinkage & Perfect Fitting Available in classic 1.7:1 and 2:1 shrink ratios, covering multiple conventional and special specifications. The tube shrinks evenly and rapidly after heating, closely wrapping irregular components such as wire harness joints and connectors without gaps or bulges. The soft and flexible material can resist bending and twisting without peeling off, ensuring long-term fitting protection.
Multi-Durability & Environmental Adaptability The product has outstanding aging resistance, ultraviolet resistance and chemical corrosion resistance, effectively resisting acid and alkali erosion, moisture, dust and oxidation. It supports long-term indoor and outdoor use with a service life several times longer than ordinary heat shrink sleeves. In addition, it has flame-retardant self-extinguishing performance, which will not spread flames in case of circuit sparks, reducing equipment fire risks.
