WebNov 1, 2024 · PCTFE, which stands for Polychlorotrifluoroethylene, is a strong plastic with great thermal properties. It is non-flammable and has a working temperature range of -240⁰C (-400⁰F) to 150⁰C (302⁰F) with a crystallinity of 85-90%. This polymer contains a high amount of chlorine, making it resistant to most chemicals and oxidizing agents.
