High-temperature PET tape, also known as Green tape or high temperature masking tape, is a polyester tape consisting of a high-performance PET film as the substrate and coated with an organic silicone-based pressure-sensitive adhesive.The substrate of high-temperature PET tape is made of a polyester film that can withstand temperatures up to 180°C or even higher. The selection of polyester film determines the high-temperature resistance of the tape, and it can maintain stable adhesive performance under high-temperature conditions. Moreover, it utilizes a silicone adhesive that can withstand temperatures up to 180°C, ensuring that the bonding ability does not deteriorate due to high temperatures. The high-temperature resistance of both the substrate and the adhesive determines the high-temperature performance of PET high-temperature tape, allowing it to achieve optimal adhesive results even in high-temperature environments.
