现在市场上称作塑料光亮剂的产品可分为4类。
Now the products in the market called plastic brighteners can be divided into 4 categories.
1、聚乙烯蜡一特征：低分子蜡与乙烯的聚合物，熔点101度。在塑料上的主要用途，作为润滑剂使用，能提高熔体的流动性，但过多会层析，使产品不合格，特别是电线。
1, polyethylene wax is a feature: low molecular wax and ethylene polymer, the melting point of 101 degrees. The main use on plastic, used as a lubricant, can improve the fluidity of the melt, but too much chromatography to make the product disqualified, especially wire.
2、高熔点蜡一特征：低分子合成蜡，熔点在110度左右，在塑料上的主要用途，作为外润滑剂使用。
2, high melting point wax is a feature: low molecular synthetic wax, the melting point is about 110 degrees, the main use on plastic, as an external lubricant.
3、高分子物质与蜡的接枝共聚物一特征：分子量比较高，熔点可达到210度。在塑料上的主要用途是在塑料制品表面成膜，以提高塑料制品表面的光亮度及平滑度。
3. One characteristic of the graft copolymer of polymer and wax is that the molecular weight is higher and the melting point can reach 210 degrees. The main purpose of the plastic is to make film on the surface of the plastic to improve the brightness and smoothness of the surface of the plastic.
4、进口的塑料光亮剂(目前真正是进口的，只有颗粒状)一特征：分子量比较高(约17000左右)，熔点可达160度。在塑料上的主要用途是在塑料制品表面成膜，以提高塑料制品表面的光亮度及平滑度。
4. The imported plastic brighteners (which are currently imported, only granular) are characterized by a high molecular weight (about 17000) and a melting point of up to 160 degrees. The main purpose of the plastic is to make film on the surface of the plastic to improve the brightness and smoothness of the surface of the plastic.
