high mechanical strength (55 - 75 MPa) and hardness
high service temperature (220 - 260 °C),
good wear resistance at elevated temperatures, too
low coefficient of friction on grinded steel,
good dimension stability
excellent chemical resistance
good electrical insulating capability (natural)
difficult to burn
reistance to high energy radiation
Cutting (turning, milling, drilling, sawing): hard metal, diamond can be used only in sharp design. Cooling is recommended, which allows high cutting rates, e. g. v = 250-500 m/min for turning and milling, v = 10 –30 m/min for drilling.
Adhesive bonding: feasible.
DOCATRON (PPS - polyphenylene-sulphide) Products
Unreinforced, unfilled PPS, with excellent resistance to chemicals and durable heat resistance up to 200°C.
DOCATRON PPS GF40
Due to the glass fiber reinforcement, the dimensional stability and thermal shape stability is significantly improved. Its short-term thermal rating reaches 280°C.
DOCATRON PPS HPV
Compared to the natural PPS it has improved sliding behaviour with better dimensional stability due to glass fiber and lubricant reinforcement.
DOCATRON PPS PVX
Carbon fibre, PTFE and graphite reinforced composite version for better sliding properties and wear resistance comparing to the natural PPS.
