Dear friends and readers, I hope you would have enjoyed reading our previous issue. Once again, I am delighted to bring for you the new edition of your favourite magazine Microbioz India. It is a “Laboratory Edition” supported by the cover story titled FEP tubing & its rising demand by Shrikant Dethe B.Tech. Chemical Engineer – IIT Bombay Ami Polymer Pvt. Ltd. The accidental discovery of PTFE in 1938 by Dr. Roy J. Plunkett has turned out to have the lowest coefficient of friction of any known solid material. But as PTFE lacks the melt-processability, a need of other fluoropolymers was generated. FEP shares the same basic monomer and is commercially obtained by free-radical polymerization in an aqueous media via addition of tetrafluoroethylene TFE,   CF2CF2 and hexafluoropropylene HFP, CF3-CFCF2.
