It is a type of film made of polytetrafluoroethylene (PTFE), which is a synthetic fluoropolymer of tetrafluoroethylene. PTFE is well known for its non-stick properties and resistance to heat, chemicals and wear. This type PTFE film is used in various industries due to its non-stick properties, heat resistance and chemical resistance. This tape is commonly used in the packaging industry for thermal insulation, in electrical applications to insulate wires and cables, and in mold release processes to prevent sticking. It is also used in covering machinery to reduce friction and wear, and in food processing equipment to prevent food from sticking to surfaces. These properties make PTFE film ideal for environments that require durability and performance at high temperatures and chemical exposure.
