塑料光亮剂的基本原理是在制品表面形成一层薄的膜层，使制品表面的平滑度和光泽度得到大大改善，制品的外观显著提高。
The basic principle of plastic brightener is to form a thin film on the surface of the product, which can greatly improve the smoothness and gloss of the product surface and the appearance of the product.
因此塑料光亮剂一般和树脂不完全相容，加工过程中可以游离到产品的表面，常用的光亮剂有氟化物，有机硅化物，PE腊，PP腊，EBS，芥酸酰胺等，更多的是这些助剂的混配物，用量视助剂而定，一般低于1％ 。
Therefore, plastic brighteners are generally incompatible with resins, and can be free to the surface of products during processing. Commonly used brighteners are fluoride, organosilicide, PE wax, PP wax, EBS, erucic acid amide and so on. More of them are mixtures of these additives. The dosage depends on the additives, generally less than 1%.
