1
stability additives

 

stability additives resistant oxidation additives, light stabilization additives and acid in and additives and other. main/primary used for anti polymer in 运输, processing molding and use process in oxidation degradation, 维持材 material property can and appearance.

2
flame retardant

 

flame retardant is can improvement can material property can chemical industry additives, flame retardant modified rear polymer material, in to 火源攻击时 can has retardant 止, or 终止火焰 传播, from to flame retardant function.

3
nucleating agent / transparent agent

 

crystallization promote agent nucleating agent, is suitable for semi crystallization plastics, 透 改变 plastics crystallization is, to shrink short molding cycle, improve/increase products optical property can and material mechanical properties new function additives

4
anti-static agent

 

polymer scratch easy generate electrical easy 引起危险甚至 is 火灾, therefore remove plastics products upper belt/tape electrical. anti-static agent can decrease light plastics in processing and use process in electrical 积累, reduce material surface resistivity.

5
processing additives

 

processing additives is used for improvement plastics processing property and molding property can additives, usually is viscosity or surface can low, has lubricated function additives. increase agent, lubricant, dispersant, demolding agent and other .

6
silicon coupling agent

 

in polypropylene (PP) polymerization in, to electronics and catalytic agent to important function. through selection to electronics can product 立构规整 degree, from made most polypropylene (PP) product property can and application .
