Dia 25mm~80mm 2:1 Heat Shrink Tubing (2M/10M/1Roll) (Copy)

Dia 25mm~80mm High Toughness 2X Heat Shrink Tube, No‑Adhesive Polyolefin Heat Shrink Sleeve, Multiple Sizes & Colors for Electrical Wiring, Copper Bar & Bus Bar Insulation Product Description This is 2:1 fast heat‑shrink tubing with national standard thickness, high toughness, wear‑resistant and anti‑aging, safe insulation performance up to 1000V rated voltage. It is non‑adhesive polyolefin heat shrink tube, featuring fast 2‑times shrinkage rate. For example, Φ5mm shrinks to 2.5mm maximum, Φ10mm shrinks to 5mm maximum. Multiple inner diameters are available: 1mm‑80mm, colors include black, red, green, yellow, blue. Length options: 2m, 10m, full roll. Sizes above 8mm are flat‑shaped. Important Note: The model number represents the inner diameter before shrinkage, not the flattened width. Actual inner diameter is larger than marked specification (e.g., Φ1mm actual inner diameter is 1.5mm). Widely used for wire insulation, cable repair, busbar, copper bar protection, electrical wiring harness insulation and DIY electronic projects. Key Features 2:1 fast shrink ratio, non‑adhesive design High toughness, thickened material, wear‑resistant & anti‑aging 1000V high‑voltage insulation, safe & reliable Waterproof, dustproof, flexible & easy to operate Multiple sizes, colors and lengths for flexible selection Wide application for electrical wiring, busbar & copper bar protection Specification Attribute Name Attribute Value Product Name 2:1 Heat Shrink Tubing Material Polyolefin (Non‑Adhesive) Shrink Ratio 2:1 Fast Shrinkage Rated Voltage 1000V Inner Diameter Options 25/30/35/40/50/60/70/80mm Color Options Black, Red, Green, Yellow, Blue Length Options 2m, 10m, Full Roll Shape Round (≤7mm), Flat (≥8mm) Features High Toughness, Thickened, Wear‑Resistant, Anti‑Aging, Waterproof, Electrical Insulation Application Wire Insulation, Cable Repair, Busbar & Copper Bar Protection, Electrical Wiring Harness, DIY Electronic Projects Note Model refers to pre‑shrink inner diameter, not flattened width; actual inner diameter is larger than marked size Heat Shrink Tubing Specification Table Buyer Notice: The model number refers to the inner diameter before shrinkage, not the flattened width. Actual inner diameter of all sizes is larger than marked specification (e.g., Φ1mm actual inner diameter is 1.5mm).
