Engineering plastic Pps bushing
PPS is a semi-crystalline high performance thermoplastic with optimised tribological properties for demanding bearing and friction requirements.
Characteristics:
· Very good sliding properties even without lubrication
· Good thermal mechanical bearing strength
· Good chemical and hydrolysis resistance even against superheated steam
· Very wear resistant
· Very rigid
· Creep resistant
· Not electrically insulating
· Good machinability
· Resistant to gamma radiation
· Self extinguishing V-0
The preferred fields of use for PPS are; Mechanical and automotive engineering, nuclear and vacuum technology, transport and conveyor technology, pump technology, textile, packaging and paper processing machinery, precision and chemical engineering, plant construction, aircraft and aerospace industry.
Applications:
· Friction bearings
· Static / dynamic high bearing strength parts
· Slide shoes
· Sealing rings
· Pump housings / parts
· Wear strips
· Gears
· Thrust washers
· Ball valve seals
· Slide rings
