Features


Plastic machine screws are different from metal screws , they are light weight and quite good on corrosion resistance , there are more features for plastic machine screws as following .


Wear resistance


Good self-lubricant


High mechanical property


Resistant high temperature

Normally , plastic machine screws can be operated smoothly at temperature 150℃ and thermal deformed temperature is up to 250℃ when parts with glass fiber .


Perfect elongation

Elongation at break is 2.2% according to ISO 527 testing method .


Corrosion resistance


Good insulation

Specific volume resistance is 1.83×1015 and resistance to high breakdown voltage support part to be good insulated .


Resistant impact

60 – 80 KJ/M2 normally .


Resistant fire

Generally , the fire resistance is UL94V-2 and UL64V-0 for special parts .


Resistance to low temperature

Plastic machine screws can be workable at -30℃


Environment friendly

Plastic machine screws meet RoHS or REACH environmental production standard .


Application


Plastic machine screws are widely used to various fields that with light load and strict conditions on corrosion resistance and insulation as perfect features .


1 , Car industry
