AIS - Dual Wall Heat Shrink Tubing
Applications
The outer layer is made of radiation cross-linked polyolefin, and the inner layer is coated with hot melt adhesive. After heating, the outer protective layer is formed, and the inner hot melt adhesive forms an adhesive layer which can protect against water and fix the object firmly, and has good adhesion to rubber, PVC, PE, and aluminum. This tubing can be used in various fields of repairing wires and waterproof requirements.
