塑料增加亮度用光亮剂
Brightening agent for brightening plastics
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。在聚乙烯和聚丙烯薄膜、线材、电缆、PP、PE、PA、PBT、PVC、ABS、AS、POM、EPE、EVA等及工程塑料和改性塑料中添加本品,能降低动、静磨擦系数,提高加工性(高流动性、低能耗性、消除气泡等),解决高速加工时因磨擦造成的静电危害,防止薄膜的粘连和开口性差,提高薄膜的手感以及光洁度和光滑性。
The basic principle of plastic brightener is to form a thin film on the surface of the product, which can songjiaoyou.07858.net diandongm.89ix.comfangdaomenw.89ix.com fengmao.89ix.comjialouyi.89ix.comtiaojiefad.89ix.comgreatly improve the smoothness and gloss of the product surface. Therefore, plastic brightener is generally incompatible with resin, and can be free to the surface of the product in the process of processing. Adding this product to polyethylene and polypropylene films, wires, cables, PP, PE, PA, PBT, PVC, ABS, AS, POM, EPE, EVA, engineering plastics and modified plastics can reduce dynamic and static friction coefficients, improve processability (high fluidity, low energy consumption, elimination of bubbles, etc.), solve electrostatic hazards caused by friction during high-speed processing, and prevent adhesion and poor openness of films. To improve the handle, smoothness and smoothness of the film.
1、光亮效能高而持久,不能轻易抹去,表面成膜。
1. High and lasting brightness, can not be easily erased, surface film.
2、不降低塑料制品的物理性能及二次加工的性能。
2. The physical properties and secondary processing properties of plastic products are not reduced.
3、本身热稳定性及化学稳定性优良,在加工过程中不分解不挥发。
3. It has excellent thermal and chemical stability, and does not decompose or volatilize during processing.
就塑料而言,由于各种塑料的分子结构不同,很难有一款塑料光亮剂能通用于各种塑料。为此给出如下建议:要选择适合自己所用塑料原料的塑料光亮剂。
As far as plastics are concerned, due to the different molecular structures of various plastics, it is difficult to have a plastic brightener that can be used in various plastics. For this reason, the following suggestions are given: we should choose plastic brighteners suitable for our plastic raw materials.
