**Product Description**

Fiberglass high temperature tape, also known as glass cloth tape or high-temperature glass fabric tape, is manufactured using high-strength E-glass fiberglass cloth as the backing material, coated with high-performance high-temperature resistant pressure-sensitive adhesive (typically silicone or acrylic).

 

Fiberglass cloth inherently offers excellent high-temperature resistance, high tensile strength, and dimensional stability. After adhesive coating, the tape combines the mechanical properties of glass cloth with the convenience of pressure-sensitive adhesion, making it widely used in electronics, aerospace, automotive manufacturing, high-temperature masking, coil winding, and related applications.
