Composition of plastic auto molds
The plastic we usually use is not a pure substance. It is made up of many materials. Among them, macromolecular polymers (or synthetic resins) are the main components of plastics. In addition, in order to improve the properties of plastics, various auxiliary materials such as fillers, plasticizers, lubricants, and stabilizers are added to macromolecular compounds. , colorants, antistatic agents, etc., can be a good plastic.
Plastic additives, also known as plastic additives, are compounds that must be added to improve the processability of polymers (synthetic resins) when they are processed or to improve the properties of the resins themselves. For example, in order to reduce the molding temperature of the polyvinyl chloride resin, the plasticizer is added to make the product soft and flexible; and for example, a foaming agent is added in order to prepare a foam with a light weight, vibration resistance, heat insulation and sound insulation; some plastics are hot The decomposition temperature is very close to the molding processing temperature and cannot be molded without the addition of a heat stabilizer. Therefore, plastic additives occupy a particularly important position in the plastic molding process.
