Silicone High Temperature Heat Shrink Tubes
Meta Description
High temp silicone heat shrink tubes with‑50℃~200℃ continuous working temp, 1.7:1 /2:1 shrink ratio. RoHS REACH compliant. Custom size, color, length for automotive, electronics, aerospace wiring harness protection. Contact us for wholesale quotation.
1. Product Overview
Our silicone high‑temperature heat‑shrink tubes are radiation‑crosslinked silicone rubber sleeving. Upon heating, they tightly shrink onto wires, cables, terminals and components for dependable electrical insulation, strain relief and environmental protection.
Outperforming PVC and polyolefin alternatives, they retain great flexibility across extreme high‑low temperatures. Commonly used in electronics, automotive wiring harnesses, new‑energy equipment, aerospace, industrial motors and medical devices.
Full OEM & ODM support covers custom inner diameter, wall thickness, length, Pantone colors, printing marks and packaging. RoHS & REACH compliant. Flexible MOQ, pre‑production samples and fast lead‑time available. Contact us for competitive wholesale pricing.
2. Key Product Features
Ultra‑wide Temperature Resistance: Continuous working from ‑50℃ to +200℃, short‑term peak at 250℃. Remains elastic without hardening or cracking during thermal cycling.
Reliable Electrical Insulation: High dielectric strength and great corona‑resistance, avoids short‑circuits and leakage for high‑voltage wiring.
Excellent Shrink Performance: Standard 1.7:1 / 2:1 shrink ratio; full shrink at 150‑175℃ (heat gun / oven). Conforms closely to irregular profiles.
Flexible & Tough: Stays soft after shrinking; high tensile & tear strength, abrasion resistance to lower stress on wire terminals.
Chemical & Weather Resistance: Resists oil, acid, alkali, solvents, ozone and UV aging, ideal for outdoor and harsh industrial conditions.
Optional Flame Retardancy: VW‑1 flame‑retardant grade on request.
Fully Customizable: Custom ID, wall thickness, cut‑to‑length, colors, surface marking, private labels and packaging.
