Teflon PTFE
Teflon PTFE is one class of plastics known as fluoropolymers. Polymers are compounds formed by chemical reactions that combine particles into groups repeating large molecules. Many common synthetic fibers are polymers, such as polyester and nylon. This type of Gland Packing Teflon is a form of tetrafluoroethylene terpolymerized. PTFE has unique properties, which make it valuable in many applications.
