PET high temperature tape, also known as polyester tape or PET tape, is a specialized tape manufactured using PET (polyethylene terephthalate) film as the backing material, coated with high-performance pressure-sensitive adhesive (acrylic or silicone).

PET is a polymer material known for its excellent dimensional stability, thermal stability, and chemical stability. When fabricated into tape form, it offers superior mechanical strength, temperature resistance, electrical insulation, and die-cutting performance. It is widely used in electronics, high-temperature painting masking, lithium battery manufacturing, and the automotive industry.
