Application areas:

It is mainly used for insulation protection of intermediate and terminal joints of high-voltage cables with flame retardant requirements, insulation protection of various busbars, and corrosion protection and wear resistance of various pipelines.

Product Description

Product Introduction:

Flame-retardant adhesive-coated thick-walled pipes are composed of two layers: an outer layer of polyolefin flame-retardant material and an inner layer of hot-melt adhesive. The outer layer is polyolefin, and the inner layer is hot-melt adhesive. They offer excellent insulation, sealing, waterproofing, resistance to mechanical wear, moisture resistance, and impact resistance. They are primarily used for insulation protection of high-voltage cable intermediate and terminal joints requiring flame retardancy, insulation protection of various busbars, and corrosion and wear resistance of various pipelines.
