Mylar tape is a polyester film tape made from **PET (polyethylene terephthalate)** film coated with a pressure-sensitive adhesive.

This material provides excellent electrical insulation, heat resistance, and dimensional stability, making it ideal for use in electronics, batteries, transformers, and industrial insulation.

Mylar is the trade name for polyester film originally developed by DuPont, which is widely used in electrical insulation applications.
