Plastic Resins Directory
1.3 Super Engineering Plastics
PEEK / Polyether Ether Ketone
Among the highest-performance plastics, withstanding temperatures above 250°C. Used in aerospace, medical implants and semiconductor equipment.
PTFE / Polytetrafluoroethylene / Teflon
Extremely low friction and almost complete chemical resistance. Used for non-stick cookware coatings, chemical-resistant tubing and gaskets.
PPS / Polyphenylene Sulfide
High heat-deflection temperature and chemical resistance. Increasingly used for parts around car engines and to reduce vehicle weight.
PI / Polyimide
Handles temperatures from sub-zero to several hundred degrees Celsius. Essential for semiconductor insulating films and the flexible circuit boards (FPCB) in smartphones.
LCP / Liquid Crystal Polymer
Flows like a liquid crystal when molten, allowing very thin, precise parts. Used in ultra-compact smartphone connectors and antenna modules.
