The role of the lubricant is to reduce the friction

  • October 12, 2017 6:47 PM PDT

    The role of the lubricant is to reduce the friction between the material and the surface 
    of the material and the processing equipment, thereby reducing the melt flow resistance, 
    reduce the melt viscosity, improve the melt flow, to avoid the melt and equipment adhesion, Surface finish and so on. 
    Mainly saturated hydrocarbons and halogenated hydrocarbons, fatty acids, fatty acid esters, 
    aliphatic ester amines, metal soap, fatty alcohols and polyols and so on. 
    1, saturated hydrocarbons 
    Non-polar hydrocarbons sample company profile import and export(such as polyethylene wax and polypropylene wax) 
    Polar hydrocarbons (such as chlorinated paraffins, oxidized polyethylene, etc.). 
    Liquid paraffin (C16-C21, i.e., white oil), solid paraffin (C26-C32, natural paraffin) 
    microcrystalline paraffin (C32-C70, high melting paraffin) and low molecular weight polyethylene (polyethylene wax) Paraffin wax 
    2, metal soap 
    Calcium stearate, lead stearate 
    3, aliphatic acid amines 
    Ethyl bis-stearic acid amide, N, N-ethylene bis ricinoleic acid amide 
    4, fatty acids 
    5, fatty acid esters 
    Butyl stearate Glyceryl monostearate Ester wax and saponification wax are mainly used for HPVC 
    6, fatty alcohols95 series pvc window profile scrap plastic pvc profile for window 
    Such as pentaerythritol 
    Processing modification additives 
    Commonly used processing modifier - ACR 
    ACR is a copolymer of methyl methacrylate and monomers such as acrylate and styrene. 
    In addition to the processing aids can be used, but also can be used as impact modifier 
    In the PVC plastic doors and windows profiles generally use ACR201 or ACR401
