    RAL9003 White Plastic Injection Molding Products , Round Base Washer Shim 5 X 50 mm


    RAL9003 White Plastic Injection Molding Products , Round Base Washer Shim 5 X 50 mm


    Round body base washer shim is made of POM plastic injection molded for application on household appliances . Base washer shim is a plate with holes that spread on , these holes are supporting fixing place to other objects so that base washer protect components are not be scratched .


    One side of plastic injection molded base washer shim with socket holes which can be inserted into groove in object for fixing base washer .


    Material


    Base washer plastic injection molded is made of POM that with good characteristics for household appliances


    High mechanical strength

    Tensile strength can be up 50.5MPa . close to metal properties . and only a tiny change on mechanical strength even working temperature has a large change .


    High stiffness

    The maximum specific stiffness for POM can be up to 2650MP


    Good wear resistant

    Wear resistant strength still keeps 35MPa or so even item is put 10 J variable load . it is best compared to items that with PA,ABS,HPVC,PS,PC


    Resistant impact

    POM has good impact resistance but inferior to ABS and PC , Impact performance will be down 90% or so if there is breaking on or in product .


    Self-lubricant

    POM parts with F4 , C ,MoS2 ,PE and lubricant elements that improve self-lubricant performance .


    Stability in dimensions

    POM part with good tensile strength and hardness that not easy to be deformed and broken .


    Resistant Organic solvent

    POM parts are resistant for hydrocarbon ,alcohol ,ether ,aldehyde , gasoline ,lubricant and Weak Alkalis .


    Small creep properties

    Creep property rate is 2.3% or so in 20℃,21MPa,3000h . and nearly not be effected by temperature


    Good insulation

    POM items nearly not be effected by temperature and humidity on insulation . insulation is related with the thickness of items , eg when thickness is 0.127mm insulation is 82.7kV/mm,thickness is 1.88mmi insulation is 23.6kV/mm


    Low water absorption


    Specification


    POM injection molded base washer shim parts are customized according to requests of fittings .


    Outside diameter : 55 mm


    Thickness : 1.5 mm
