The term "polyurethane fibreglass sleeve" (also known as "PU fibreglass sleeve" or "polyurethane coated fibreglass sleeve") refers to a protective covering used for wires, cables, and hoses that provides electrical insulation, mechanical strength, and resistance to various environmental variables. This sleeve is made by applying a layer of polyurethane to a woven or braided fibreglass base, creating a robust and adaptable protective solution. A detailed explanation of a polyurethane fibreglass sleeve is provided below:
A fibreglass base material is commonly impregnated with a coating of polyurethane resin to create polyurethane fibreglass sleeves. A protective sleeve made of fibreglass and polyurethane provides both mechanical strength and electrical insulation.
