Fita isoladora de fibra de vidro e poliéster 3M 19mm x 20m preta reforçada com fibra de vidro (80000208027)

Electrical insulation in high-temperature environments demands a tape that can withstand mechanical stress and thermal cycling without losing its dielectric properties. The 3M Glass Fiber Reinforced Polyester Electrical Insulation Tape provides a robust solution for coil wrapping, transformer insulation, and motor lead anchoring, combining a thermosetting rubber adhesive with a glass fiber reinforced polyester film backing for reliable performance up to 155°C.

Who is it for

This tape is intended for electrical engineers, motor manufacturers, and maintenance professionals who need a durable, high-temperature insulation material for demanding applications. It is suitable for use in coil wrapping, transformer insulation, and mechanical protection of electrical components where high mechanical strength and solvent resistance are required.

Main features

• Glass fiber reinforced polyester film backing provides high tensile strength and resistance to tearing.
