High mechanical property
Resistant high temperature
Normally , the part can be operated smoothly at temperature 150℃ and thermal deformed temperature is up to 250℃ when parts with glass fiber .
Elongation at break is 2.2% according to ISO 527 testing method .
Specific volume resistance is 1.83×1015 and resistance to high breakdown voltage support part to be good insulated .
60 – 80 KJ/M2 normally .
Generally , the fire resistance is UL94V-2 and UL64V-0 for special parts .
Resistance to low temperature
Plastic spur gear can be workable at -30℃
