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,

CF2=CF2) and hexafluoropropylene (HFP, CF3-CF=CF2).
