Introduction
A thin-walled, soft, flame-retardant, double-walled polyolefin heat-shrinkable tube with adhesive is used for parts or parts of military equipment that need to be waterproofed and sealed, and can be widely used for sealing and moisture-proof protection of cable end connectors or electronic components.

Features
Operating temperature: -55~110 ℃
Minimum full shrinkage temperature: 125 ℃
Shrink ratio: 3:1 & 4:1
GJB 7283-2011 compliant
