This tape has good dimensional stability, thermal stability, chemical stability, as well as good initial adhesion and holding adhesion. It is easy to die-cut and has good adhesion to plastics, rubbers, nameplates, etc. The PET double-sided tape can be applied to a wider temperature range and harsh environments. The long-term temperature resistance can reach 100 - 120 °C, and the short-term temperature resistance can reach 140 - 200 °C. There are various models and specifications on the market to meet different application requirements. The PET tape, also known as the PET high-temperature tape, is another expression referring to the same product, which is mainly used in application scenarios such as the bonding of nameplates, ornaments, decorative parts, and the bonding of plastics and rubbers.
