Valve Body & Seal Materials
Introduction Page
to materials used in plastic valves
PVC
Polyvinyl chloride. Plast-O-Matic uses Geon® brand Grade 1, Type 1 PVC.
CPVC
Chlorinated polyvinyl chloride. Plast-O-Matic uses Corzan® and Temprite® CPVC. Temprite is a type of Corzan used for injection molding.
PVDF
Polyvinylideneflouride. Plast-O-Matic uses various formulas of Kynar® PVDF depending on the application.
PP
Polypropylene. Plast-O-Matic uses Natural, unpigmented homopolymer polypropylene & glass-filled polypropylene.
PTFE
Polytetrafluoroethylene. A high purity fluoropolymer. Teflon® is a popular brand of fluoropolymers.
PPO
Polyphenylene ether blended with polystyrene. Plast-O-Matic uses Noryl GFN1.
FKM
Fluoro rubber. Viton® is a popular brand of FKM.
EPDM
Ethylene Propylene Diene Monomer. An olefinic thermoplastic elastomer.
BUNA-N
Buna-nitrile rubber.
AFLAS®
Tetrafluoroethylene/propylene dipolymer.
