1.Low friction factor, almost the lowest one in all solids;
      2.Outstanding temperature stability;
      3.Extra high chemical stability and almost no corroding by any chemical;
      4.Non-sticking surface;
      5.Excellent electricl insulation stable and lowest dielectric constant in a broad range of frequency;
      6.Excellent ageing resistance against oxygen,ozone and UV;
      7.Valuable incombustible property;
      8.Very little absorbency;

      PTFE has a lot of outstanding performance, which was initially used in defence and military and frontiers of science. It applied for civil use in 1950's and people have made an uninterrupted efforts ever since to maintain and extend its outstanding advantages and overcome its disadvantages,develop various composite PTFE products and filled PTFE products,seek for new processing method to increase its adaptability and extend its application fields. Now PTFE becomes an important and indispensable material in all trades and professions.
