Introduction to Plastic Composition
The plastic we usually use is not a single component, it is made up of many materials. Among them, high molecular polymers (or synthetic resins) are the main components of plastics. In addition, in order to improve the performance of plastics, various auxiliary materials, such as fillers, plasticizers, lubricants, and stabilizers, must be added to the high molecular compounds. , Colorants, antistatic agents, etc., can become plastics with good performance.
Plastic additives, also called plastic additives, are compounds that must be added to improve the processing performance of polymers (synthetic resins) or to improve the performance of the resin itself. For example, in order to reduce the molding temperature of polyvinyl chloride resin, the plasticizer is added to make the product soft; another example is to add foaming agent for the preparation of lightweight, vibration-resistant, heat-insulating, and sound-insulating foam; The decomposition temperature is very close to the molding processing temperature, and molding cannot be achieved without adding heat stabilizers. Therefore, plastic additives occupies a particularly important position in plastic molding processing.
