The products on the market now known as plastic brightener can be divided into 4 categories.
1, polyethylene wax One characteristic: low molecular wax and ethylene polymer, melting point 101 degrees.
The main use of plastic products is to use as a lubricant to improve the fluidity of the melt, but too much will be chromatographic to make the product unqualified, especially the wires.
2, high melting point wax one characteristic: low molecular synthetic wax, melting point at about 110 degrees, the main use on plastic, as an external lubricant to use.
3, polymer material and wax grafting copolymer one characteristic: The molecular weight is relatively high, the melting point can reach 210 degrees.
The main use on plastics is to film the surface of plastic products, which can make the smoothness and smoothness of plastic products be significantly improved.
4, the import of plastic brightener (currently really imported, only granular) a characteristic: The molecular weight is relatively high (about 17000 or so), melting point can reach 160 degrees. The main use on plastics is to film the surface of plastic products to improve the brightness and smoothness of the surface of plastic products.
