Heat shrink tubing can combine various properties in a unique way Taken together, include: outstanding electrical characteristics, excellent Chemical and solvent resistance, high purity, lubricity and penetration Out of reliability. The double-layer fluoropolymer PTFE/FEP tube consists of a PTFE heat shrinkable outer layer and an FEP inner layer It is widely used and can be used with wires, cables, connectors, connectors, terminals, etc Tightly combined, with the role of moisture-proof. When the covered part is heated, PTFE contracts tightly onto the inlay while FEP melts and flows onto a solid or near-solid package, forming an extremely tight bond that can withstand maximum extension or vibration stress. double layer heat shrink tube has all the electricity of PTFE Gas, chemical and mechanical properties. Operating temperature up to 230 degrees. Our roll shrouds extend the life of the roll, enhance reliability and enhance the quality of the product. A little heat can be applied to the roll to form a layer of high strength, armor like a strong sheath, which protects the roll from chemical solvents, acids, shocks, wear, heat and moisture. It also eliminates the problem of viscous accumulation. During processing, only a convenient heat source, such as a heat gun, can be quickly and easily condensed onto the roll surface, and can be cleaned with solvents or reagents.
