Electrical Insulation Cotton Tape

Hanyao durable Electrical Insulation Cotton Tape essentially is a strip material made of high-quality pure cotton fibers through weaving or non-woven processes. It is usually chemically impregnated (such as with varnish, asphalt, or silicone oil) to enhance its electrical insulation, moisture resistance, and mechanical strength.Its base material is pure cotton, a natural cellulose fiber, which has a certain degree of insulation and flexibility.It is also necessary to impregnate with insulating varnish/oil to fill the gaps between cotton fibers and improve performance.

Why Choose This Product?

It is an economical and versatile insulating fixing material, mainly used in Class A (105°C) insulation systems.It has excellent impregnation and compatibility; the porous structure of cotton fibers allows it to fully and quickly absorb and contain the insulating varnish (impregnation varnish). During the vacuum pressure impregnation (VPI) process for motors, the varnish penetrates the cotton tape well, solidifying the windings into a strong whole.It also has good mechanical strength and flexibility.The braided structure gives it high tensile strength, allowing it to withstand significant tension when bundling coils. At the same time, it is very flexible, easily wrapping around irregularly shaped coils and ends, providing excellent fit.
