Insulation Protective Polyolefin Heat Shrink Tube for Wiring & Cable Protection
Brief Overview
Heat Shrink Tubing is a thermally shrinkable insulating tube made of high-quality polyolefin cross-linked material. With the characteristics of high shrinkage rate, fast shrinking, excellent insulation and wear resistance, the tube will shrink tightly after heating, closely fitting wires, cables, connectors and metal parts to form a tight protective layer.
Our heat shrink tubes are available in full sizes, multiple colors and standard/ flame-retardant grades. We support custom specifications, logo printing, flexible MOQ wholesale and professional OEM/ODM customization, widely exported to Europe, America, Southeast Asia and other global markets for electronic, electrical and industrial insulation projects.

Key Benefits
Excellent Insulation Performance: High dielectric strength, effectively preventing electric leakage, short circuit and electric shock risks, meeting industrial electronic safety standards.
Fast & Tight Shrinkage: Standard 2:1 shrink ratio, uniform heating shrinkage, close fitting with workpiece surface, no gaps, stable and firm wrapping effect.
Flame Retardant & Safe: Optional flame-retardant grade material, self-extinguishing without combustion, effectively blocking fire spread, suitable for high-standard electrical equipment.
Wear & Corrosion Resistant: Tough tube body, resistant to daily friction, scratch, acid and alkali corrosion, long service life for indoor and outdoor use.
Waterproof & Dustproof: Fully sealed protection after shrinking, isolating moisture, dust and oxidation, preventing wire aging and damage.
Easy Operation & High Cost-Effective: No complex tools required, fast construction, lightweight and affordable, ideal for bulk industrial matching.
