PTFE is a high performance engineering speciality polymer invented by Dr. Roy J. Plunkett at Du Pont’s Jackson Laboratory, New Jersey, US, on 6th April 1938. As the polymer was found to have exceptional properties with regards to chemical inertness, heat resistance & fricitional properties; developmental manufacturing began in 1943 with joint efforts of Kinetic Engineering Inc., USA & E.I. Du Pont de Nemours & Co. Inc., USA. The commercial production went operational by E.I. Du Pont de Nemours & Co. Inc., USA in 1948.The world wide consumption of PTFE is around 1,40,000 Tonnes per annum and is expected to grow at 10% per annum.

POLYMER SCIENCE

TFE Monomer is generally manufactured by synthesis of Calcium Fluoride(Fluorospar), Sulphuric Acid & Chloroform. The polymerisation of TFE is carried out in carefully controlled conditions to form PTFE. The chemical structure of PTFE is due to presence of stable & strong C-F bonds, PTFE molecule possess outstanding chemical interness, high heat resistance & remarkable electrial insulation characteristics, in addition to excellent frictional properties.
