Common plastic materials:
The plastic usually used is not a single component, it is formulated from 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 known as plastic additives, are compounds that must be added to improve the processing performance of the polymer (synthetic resin) or to improve the performance of the resin itself when the polymer (synthetic resin) is processed. 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 a 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.
Plastics are polymer compounds (macromolecules), commonly known as plastics or resins, which are polymerized by monomers as raw materials through addition polymerization or polycondensation reactions. The composition and shape can be changed freely. It is composed of synthetic resins and fillers. Plasticizer, stabilizer, lubricant, pigment and other additives.
