PET high -temperature tape and PTFE high -temperature tape
The tape is composed of two parts from two parts: substrate and pressure -sensitive rubber.
This article introduces two substrate materials: PET, and the Chinese name is polyphylebenate ethylene glycol, referred to as polyester, and its melting point is 250-255 ° C. PET materials are also good for wear -resistant and chemical resistance; PTFE, Chinese named polyfluorolythery, commonly known as special (iron) fluoron, its melting point is about 327 ° C. The surface of PTFE materials can be very low and smooth.
In order to achieve high temperature resistance, coated silicon -sensitive glue on the substrate.
The temperature resistance of PET high -temperature tape can reach about 204 ° C, and the temperature resistance of PTFE high -temperature tape can reach about 260 ° C.
The 3M representative PET high -temperature tape has 8991 and 8992, which can be used for difficult surface stitching such as high -temperature powder spraying, temporary protection of high -temperature environment, and silicon treatment paper. The 3M representative PTFE high -temperature tape has 5480, 5481, 5490, 5491, which can be used for high temperature removal, coating/printing rollers, and the protection of hot seals.
Some high -temperature resistance applications are not allowed to use organic silicon pressure sensitivity. PET tapes that are coated with high -temperature rubber -sensitive glue with 3M 875 and 876, the temperature resistance is 177 ° C. It can be used for vacuum of high temperature layer pressure process. Bag bonding.
