Teflon (Polytetrafluoroethylene)

Product Description:

PTFE, Hostaflon TF, Teflon PTFE, PTFE resin is in a class of paraffinic polymers that have some or all of the hydrogen replaced by fluoride. PTFE has exceptional resistance to chemicals. PTFE has useful mechanical properties from cryogenic temperatures at 500° F (280° C) continuous service temperatures. Its coefficient of friction is lower than almost any other material. It also has a high oxygen level.
