Special processing of rubber rollers (PTFE coating), Side rubber rollers provide users with PTFE coating on the surface of rubber rollers, with a thickness of 0.01~0.15mm, which is suitable for low surface energy and solvent resistance on the roller surface. Polytetrafluoroethylene (PTFE) is commonly referred to as a "non-stick coating" or "easy-to-clean material". This material is resistant to acids and alkalis, various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, and its coefficient of friction is very low, so it can be used for lubrication, and it has also become an ideal coating for the inner layer of water pipes that are easy to clean.
