Plastic Additive has a light weight, corrosion resistance, high strength, excellent electrical properties, easy processing, etc., made by the appearance of a variety of beautiful, colorful products, has become people clothing, food, shelter, the line is essential Important material. However, Plastic Additive is not perfect, if some Plastic Additive is too brittle, some flammable, and some easy to static, etc., which must join a variety of additives (also known as additives) to improve the performance of Plastic Additive.
Additives are chemicals that are dispersed in the Plastic Additive molecular structure and do not seriously affect the molecular structure of the Plastic Additive, but can improve its nature or reduce the cost. Plastic Additive additives require high efficiency, compatibility, durability, chemical stability, non-toxic and inexpensive.
There are many varieties of Plastic Additive additives. There are antioxidants, Plastic Additiveizers, light stabilizers, metal deactivators, impact modifiers and so on. Part of the raw materials must be added additives to do the finished Plastic Additive products. An antioxidant is a chemical additive that inhibits or delays the automatic oxidation reaction. A Plastic Additiveizer is a substance that is added to a material (Plastic Additive, resin) to improve its workability, flexibility, and stretchability. Light stabilizer is a compound that inhibits light-induced degradation reactions. A metal deactivator is a compound capable of forming an inactive or almost inactive activity with a catalytically active metal. Lubricant is a compound that can reduce the frictional resistance between the parts of the product at the use temperature. This additive is particularly important for polyethylene films. The impact modifier is a polymer material that enhances the toughness of Plastic Additives.
Plastic Additive in the process of the need to add different types of additives to meet the needs of different processing and application, today briefly introduced the classification of these additives and features.
Additives are chemicals that are dispersed in the Plastic Additive molecular structure and do not significantly affect the molecular structure of the Plastic Additive but which can improve its properties or reduce costs. The addition of additives can promote the Plastic Additive to improve the substrate processing, physical, chemical and other functions and increase the physical and chemical properties of the substrate.
According to the additive type, Plastic Additiveizer is still the largest market accounted for 58%, modifier (including clarification and nucleating agent, coupling agent, impact modifier) accounted for 24%, the nature of supplements (including antioxidants, Electrostatic additives, fungicides, heat and light stabilizers, flame retardants) accounted for 11%, processing aids (including anti-caking and anti-fogging agents, lubricants and anti-slip agent) accounted for 7%. For the average annual soft PVC will reach 3.5%, mainly due to the rapid increase in demand in China. The largest growth rate is expected to be coupling agent, the average annual growth rate of up to 7%, the main uses include wood-Plastic Additive composite materials, polymer alloys, filled polymer, and other transparent polypropylene production nucleation / clarifier demand Is expected to have a faster growth. Efficient, special effects, non-toxic, pollution-free, complex multi-functional development of the global trend of Plastic Additive additives. With the development trend of Plastic Additive additives, the impact modifier mainly has the excellent performance of ACR, MBS mainly; Plastic Additiveizer to improve the special properties of Plastic Additive products, phosphate esters, epoxy esters, fatty acid esters , Polyester, trimellate Plastic Additiveizer to accelerate the development of antioxidants to complex products, especially high-molecular-weight product development boom; light stabilizer to hindered amines-based, and show high Molecular quantification, low alkalization, multifunctional, reactive and functional group diversification and other characteristics. In recent years, many new functional additives are also emerging, eye-catching nucleating agent, degradation agent, infra
