With the development of national economy, China's plastic processing industry is advancing rapidly. In recent years, the rising international crude oil price has led to a sharp increase in the price of petroleum based resins, which has led to an increase in the cost of plastic processing raw materials, thus bringing new competitive pressure to the plastic processing industry. In order to achieve the goal of increasing production and reducing consumption, energy conservation and emission reduction, the plastic industry needs to constantly improve processing technology, and at the same time, it also needs to apply efficient additives to improve efficiency.

Organic silicon polymer is a kind of special polymer material with semi organic and semi inorganic structure, which has unique and excellent properties. Organic silicon products have various forms and are widely used, so the organic silicon materials have won the reputation of "industrial monosodium glutamate" and "high-tech development catalyst". Since the reform and opening up, China's silicone industry has made great progress, not only with a sharp increase in output, but also with the expansion of product varieties and models. Due to the characteristics of organic silicon materials, the organic silicon components in the additives are both compatible and different from the plastic substrate carbon carbon chain polymer, so they can mix with each other to play a unique role, and will not be completely "submerged" and assimilated by the basic polymer. Therefore, the application of a small amount of organic silicon additives can achieve obvious improvement effects, and organic silicon materials can be used as plastic processing additives, The ideal effect of significant benefits can often be obtained by receiving small inputs.

The silicone materials used in the plastic processing field are mainly silicone polymers and silane coupling agents. Organosilicon polymer is a kind of polymer material with special structure. It has a silicon oxygen polymer skeleton similar to silicate structure, and has methyl, phenyl, vinyl, alkoxy and other organic side chains. The silicon oxygen bond energy of organic silicon polymer is high, and the molecular chain of organic silicon polymer is flexible. The special polymer structure of silicone polymer endows it with a series of excellent properties: high and low temperature resistance, hydrophobicity and moisture-proof, low surface energy, high insulation strength, low dielectric loss, weather aging resistance, etc.

The silicone products used in the plastic processing field can be divided into two categories:
(1) Application of organic silicon as the main material of plastics
The application of organic silicon as the main material of plastics is mainly based on the organic silicon resin as the basic polymer, together with other auxiliary materials, to form and process the organic silicon plastic products. The main products include silicone molding plastics, silicone laminated materials and silicone foam plastics.

(2) Application of Organic Silicon as Plastic Additive and Auxiliary Material
Organic silicon materials have various forms and varieties, and different types of organic silicon materials have different functions. In the field of plastic processing, organic silicon components are used as plastic processing aids and excipients, mainly including cross-linking agent, lubricant, dispersant, release agent, filler treatment agent, reinforcing agent, tackifier, bubble control agent, etc. The application of silicone additives can improve the processing conditions of plastics or improve the properties of plastics products. In most cases, the application of silicone additives can achieve the ideal effect of improving the process conditions and improving the quality of plastic products without increasing or even reducing the production cost.
