TECHNICAL DESCRIPTIONHydex® 4101 is manufactured from PolyButylene Terephthalate polyester (PBT-P) resin. It is a semi-crystalline thermoplastic. This material is manufactured from Celanex® resin.
GENERAL PROPERTIESHydex® 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
