Automotive injection molding manufacturers introduce the role and classification of additives
In addition to synthetic resin, some plastic accessories also contain other auxiliary materials, such as plasticizers, stabilizers, colorants, various fillers, etc., which are called multi-component plastics.
作用 The role of plastic additives in plastics:
Plastic additives The purpose of adding additives to plastics is mainly to improve processing performance, improve use efficiency and reduce costs. Additives account for a small proportion of plastic materials, but have a great impact on the quality of plastic products. Different types of plastics require different types and amounts of additives due to different molding and processing conditions and use conditions.
的 The classification of plastic additives:
Plasticizers can increase the softness, extensibility, and plasticity of plastics, reduce the flow temperature and hardness of plastics, and facilitate the molding of plastic products. Commonly used are phthalates, sebacates, chlorinated paraffins and camphor. The most common of us is camphor.
