PBT
Hydex® 4101 is manufactured from PolyButylene Terephthalate polyester (PBT-P) resin. It is a semi-crystalline thermoplastic. This material is manufactured from Celanex® resin.
GENERAL PROPERTIES
Hydex® 4101 offers excellent mechanical properties combined with good chemical resistance. PBT-P has good impact resistance and toughness, low coefficient of friction & wear, and does not need lubrication. It also is resistant to chemicals, chlorine, water, and steam.
Hydex® 4101 is available in FDA-approved white and non-FDA black colors.
Hydex® 4101L is an internally-lubricated version designed for use in higher wear resistance, PV range and lower coefficient of friction applications.
Both Hydex® 4101 and 4101L are approved for direct food contact (FDA, USDA, and 3A Dairy compliant).
KEY PROPERTIES
• No center line porosity • Superior chemical resistance • Low coefficient of friction • Good impact strength and ductility • Hard and durable surface • FDA, USDA, 3A Dairy approved grades • Replaces brass, aluminum, steel, UHMW, acetal
TYPICAL APPLICATIONS
• Food piston pumps • Valves and valve bodies • Feeder blocks • Timing screws • Gears • Cams • Bushings and bearings • Wear strips • Fuel pump components • Fuel system connectors and rotors
