Product Details

Basic performance:

Material: rigid cross-linked polyolefin outer layer, hot-melt glue inner layer;
shrinkage ratio: 4:1;
start shrinkage temperature: 70°C;
complete shrinkage temperature: 120°C;
continuous working temperature: -45°C～125°C.

Features:

Flame retardant, semi-rigid, providing stress relief and anti-wear protection;
hot melt adhesive has a wide operating temperature range and can bond multiple conductors of different materials;
effectively shields oil and water vapor, and protects wiring harnesses from corrosion and water seepage;
shrinkage The ratio is large, and it can encapsulate irregular joints and components of different sizes.

Application fields:

Environmental sealing of wire harness connectors, terminals and components in the automotive industry;
insulation protection of various wire harnesses.
