Polyolefin Material:3:1 heat shrink tubing is a heat shrink sleeve made of polyolefin material. The outer layer is made soft cross linked polyolefin material, which has the characteristics of insulation, corrupt resist and wear resist.
With Glue:The inner wall of the 3:1 heat shrink tubing contains a small amount of glue, which melts and adheres to the superficial of the object during heat shrinkage, better wrapping the object and making it insulated and less likely to be damaged.
3:1 Shrinkage Rate:The shrinkage ratio of heat shrink tubing is 3:1 During heat shrinkage, The heat shrink tubing will shrink to one third of its original size, allowing it to be better wrapped and less likely to fall off.
Shrinkage Temperature:The shrinkage temperature of 3:1 heat shrink tubing is 70Deg C, At 70 degrees Celsius At C, the heat shrink tube will start to shrink, and after about 3 seconds, the heat shrink tube will finish shrinking and wrap around the item.
Insulation Protection:3:1 heat shrink tube is wear resist and corrupt resist, with excellent retardancy and insulation properties, providing excellent protection for wrapped items.
