Safe and Environmental Friendly Material Shrink Wrap: Conform to UL224, CSA C22.2, RoHS standard and Sony-SS-00259 standard. Electrical heat shrink tubing material composition does not contain heavy metal and other environmentally hazardous substances. No slowly or long-term virulence. No need to worry about your health when using heat shrink wrap.

Premium Quality Heat Shrink Tubing Set: Excellent flame retardant (UL 224, VW-1) and insulation performance. Soft and flexible wire shrink wrap, low shrinkage temperature-minimum shrinkage temp: +158℉(+70°C), fast shrinkage, easy and convenient to use with a heat gun.

Effective and Long Lasting Protection: heat tube shrink has the advantages of good tightness, acid and alkali resistance, durable and anti-aging. Shrink wrap wire tensile strength: 14 Mpa. Dielectric strength: >20kV/mm. Elongation at break: >400%. Volume resistivity: >1.0× 10^14Ω.cm. Cold-resistant bending -22℉(-30 °C) × 1h without cracking. Use heat shrink tubes instead of ugly and short-lived electric tape.
