VERSATILE HEAT SHRINK TUBING
SUPER VERSATILE HEAT SHRINK TUBING
3:1 SHRINK RATIO
Adopting dual wall tubing design has the increased ability to stand up to wear and tear.3:1 SHRINK RATIO, it can shrink to 1/3 of the original diameter, the shrinkage temperature is 125°C (257°F), and the withstand voltage is 600V and high flame retardant coefficient.When the Heat-shrink tube shrinks, the glue film on the inner wall will melt and then it will be adsorbed on the surface of the object tightly so as to connect tightly, insulate, and seal off perfectly.
Heat Activated Adhesive Lining
This is a waterproof shrink tubing with the internal adhesive layer. When heat is applied, shrink tubing recovers and the internal adhesive layer melts. A small fillet of clear adhesive (about 1 mm wide) becomes visible at the end of the heated tubing. When cooled down, it forms a rigid seal. Heat activated glue strongly adheres to wires, terminals or any other surfaces. When adhesive flows, it pushes the air out and fills any gaps between the wire and the tubing, which makes the connection waterproof. For best results we recommend using a heat gun.
Dual Wall Shrink Tubing
Dual wall marine grade heat shrink tubing provides better rigidity and abrasion resistance. Dual wall tubing design has the increased ability to stand up to wear and tear. This wire heat shrink tubing is flame retardant. our tubing is built to withstand the most demanding conditions, ensuring longevity and maintaining optimal performance over time.
Multiple Certifications
This industrial grade heat shrinkable tubing is compliant with all relevant electrical standards such as: UL, SGS, RoHS, Reach, and ISO9001.
