What is General Plastic? General-purpose plastics generally refer to plastics with large output, wide use, good formability, and low prices. There are five types of general plastics, namely polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and acrylonitrile-butadiene-styrene copolymer (ABS). These five types of plastics account for the vast majority of plastic raw materials,…
What are the ingredients of plastic? Colorant The colorant can make the plastic have various bright and beautiful colors. Commonly used organic dyes and inorganic pigments are used as colorants. The natural color of synthetic resin is mostly white translucent or colorless and transparent. Colorants are often used in industrial production to increase the color…
Plastic composition: plasticizer & stabilizer Plasticizer Plasticizers, or plasticizers, can increase the plasticity and flexibility of plastics, reduce brittleness, and make plastics easier to process and shape. Plasticizers (plasticizers) are generally miscible with resins, non-toxic, odorless, high-boiling organic compounds that are stable to light and heat. The most commonly used are phthalate esters. For example,…
Plastic composition: synthetic resin & filler Synthetic resin is the most important component of plastics, and its content in plastics is generally 40% to 100%. Because of the large content and the nature of the resin often determines the nature of the plastic, people often regard the resin as a synonym for plastic. For example,…
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,…
Advantage of plastic 1. Most plastics have strong corrosion resistance and do not react with acids and alkalis. 2. Plastic manufacturing costs are low. 3. Durable, waterproof and light weight. 4. It is easy to be molded into different shapes. 5. It is a good insulator. 6. Plastics can be used to prepare fuel oil…
Plastic molecular structure There are basically two types: the first is a linear structure, a polymer compound with this structure is called a linear polymer compound; the second is a body structure, and a polymer compound with this structure is called a bulk polymer Compound. Some macromolecules are branched, called branched macromolecules, which belong to…
The main characteristics of plastic 1. Most plastics are light, chemically stable, and will not rust; 2. Good impact resistance; 3. It has good transparency and abrasion resistance; 4. Good insulation and low thermal conductivity; 5. General formability, good coloring, low processing cost; 6. Most plastics have poor heat resistance, high thermal expansion rate and…
Plastics are polymer compounds (macromolecules) that are polymerized by addition polymerization or polycondensation reactions with monomers as raw materials. They have moderate deformation resistance and are between fiber and rubber. They are composed of synthetic resins, fillers, plasticizers, and stabilizers. It is composed of additives such as agents, lubricants and pigments. The main component of…
