Lubricants
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
