如今在废塑料市场当中，添加剂成分必不可少。因为添加剂成品既可以起到中和、高效的作用，同时也可让废塑料成分值增大，应用范围更广泛。配料时选用助剂的总原则是既保证再生制品具有一定的性能，符合使用要求，又不至于成本过高。一般来说，考虑以下原则：
Nowadays, in the waste plastic market, additives are essential. Because the additive can not only play a neutral and efficient role, but also make the value of the waste plastic increase, and the application range is more extensive. The general principle of selecting auxiliaries in the ingredients is to ensure that the regenerated products have certain performance, meet the requirements of use, and are not too high in cost. Generally speaking, the following principles are considered:
（1）由于废旧塑料和再生制品的价格较低，因此所采用的添加剂也要便宜；
(1) because of the low price of waste plastics and recycled products, the additives used are also cheap.
（2）正因为废旧塑料往往是各种颜色废料的混合物，在再生加工时一般添加深色着色剂，故对所选用助剂的外观色泽要求不高；
(2) because waste plastics are often mixtures of all kinds of color waste, the dark coloring agent is usually added in the regeneration process, so the requirement for the appearance and color of the selected additives is not high.
（3）同时添加剂应能满足再生制品的一定性能要求。因此在处理废旧塑料时要遵循一定的原则方法，同时也应兼顾塑料成分，这就要求我们全面了解废旧塑料知识，在日后的需求当中，能够很好地加以利用。
(3) at the same time, the additive should be able to meet the certain performance requirements of the regenerated products. Therefore, in the treatment of waste plastics should follow certain principles and methods, but also should take into account the plastic component, which requires us to fully understand the knowledge of waste plastics, in the days after the demand, to good use.
