    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℃
