General Information

This high flame-retardant Dual Wall heat shrink tubing for automobile wiring harness is composed of polyolefin and flame-retardant hot melt adhesive.
The outer layer is made of polyolefin insulating and flame-retardant material.
The inner hot melt adhesive is flame-retardant and can buffer mechanical strain and excellent sealing.
This product is aimed at automotive wiring harnesses. On the basis of satisfying low temperature and high-rate shrinkage, this product improves the flame-retardant properties and overcomes and solved the environmental impact that has higher requirements on the wiring harness.
