<p>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 &ldquo;Laboratory Edition&rdquo; supported by the cover story titled FEP tubing &amp; its rising demand by Shrikant Dethe (B.Tech. Chemical Engineer &ndash; IIT Bombay) Ami Polymer Pvt. Ltd. The accidental discovery of PTFE in 1938 by Dr. Roy J.</p> <p>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, CF2=CF2) and hexafluoropropylene (HFP, CF3-CF=CF2).</p>
