Fluorosint Mica Reinforced PTFE (Teflon) Most dimensionally stable PTFE High temperature seals and valve seats, piston seal rings and bearings $$$$ 1
Techtron Polyphenylene Sulfide (PPS) Excellent chemical resistance and inertness plus ease of machining Analytical instrument components $$$$ 4
Ketron Polyetheretherketone (PEEK) Excellent chemical resistance and hight temperature wear resistance Chemical process valve seats/seals and wear parts $$$$ 5
Ultem Polytherimide (PEI) High strength, and good heat resistance to 350F. Plus high dielectric strength, low flamability and good resistance to hot water/steam Medical instruments and electrical components $$$ 4
Radel Polyarylsulfone (PAS) Best resistance to hot water/steam Surgical instrument handles and other parts exposed to hot water/steam $$$ 4
Torlon Polyamidimide (PAI) Hight strength and heat resistance to 500F High temperature bearings and highly loaded parts. $$$$$ 7
Celazole Polybenzimidizal (PBI) Highest strength and heat resistance to 800F Glass handling parts, plasma torch components $$$$$$ 9

Machining scale 1 is easiest to machine. High speed steel is typically OK for low volumes and carbide tooling best for higher volume parts.
Machining scale 9 is most difficult to machine. Polycrystalline or carbide tooling is suggested.
