HESA- PA glue semi-rigid double wall heat shrinkable tube


Product Overview:

HESA- Automobile Wire Harness Semi-hard Dual Wall Heat Shrink Tube Withe Adhesive The outer layer makes by polyolefin PE material which is flame-resistant, semi-hard and wear-resistant. High shrink ratio, good adhesion performance, and the physical &chemical properties are also good. So it can protect the wire harness very well. The inner Modified PA adhesive : High temperature resistance, waterproof, damp-proof, corrosion resistance. Apply to automobile wire harness, household wire harness, wire and cable branch, metal pipeline where need insulated protection.
