3. Polytetrafluoroethylene (PTFE) is a polymeric material that has common uses outside of dentistry. WHAT’S IT MADE FROM?? Polytetrafluoroethylene is a synthetic fluoropolymer made from the polymerization of tetrafluoroethylene (TFE) monomers

4. CHEMICAL COMPOSITION The chemical composition of PTFE thread consists of carbon and fluorine atoms. The repeating unit in the polymer chain is composed of carbon and fluorine atoms arranged in a linear fashion. The chemical formula for polytetrafluoroethylene is (C2F4)n, where "n" represents the number of repeating units in the polymer chain.

5. FEATURES

6. 01 Which means it does not adhere to other surfaces. This allows the tape to be easily applied and removed without leaving residue NON STICK 02 03 04 PTFE is highly resistant to chemicals, including acids, bases, solvents, and oils. CHEMICAL RESISTANCE Can withstand a wide range of temperatures, making it suitable for both hot and cold-water systems. TEPERATURE RESISTANCE Due to its high melting point (over 300°C) to ensure that it is sterile before use AUTOCLAVABLE 05 HYDROPHOBIC Moisture Resistance
