Plasticizers can be classified into aliphatic dicarboxylic acid esters, phthalic acid esters (including phthalates and terephthalates), benzoic acid esters, benzoic acid esters, polyol esters, chlorinated hydrocarbons, epoxies, citric esters, polyesters, etc. from the chemical structure.
Plasticizer, also known as plasticizer. Plasticizer is a polymer material additive widely used in industry. Adding this material in plastic processing can make it more flexible and easy to process, which can be legally used for industrial purposes. The clouding agent prepared by Taiwan manufacturers using a common plasticizer DEHP (DINP, DNOP, DBP, DMP, DEP, etc. were successively detected) instead of palm oil can also produce a thickening effect similar to that of emulsifiers.
Plasticizer (plasticizer) is a kind of macromolecular material auxiliary agent, and also a kind of phthalic acid esters (PAEs) in environmental estrogens. It has a wide variety, and the most common variety is DEHP (commercial name DOP). The chemical name of DEHP is di (2-ethylhexyl) phthalate, which is a colorless and tasteless liquid and widely used in industry
Silicone oil is also called polysiloxane. Its silicon oxygen bond is very stable, so silicone oil has good thermal stability and oxidation stability. At present, silicone oil used as lubricating oil mainly includes methyl silicone oil, methyl phenyl silicone oil, methyl chlorophenyl silicone oil and ethyl silicone oil. Methyl silicone oil is generally used as damping fluid and base oil for special purpose lubricating grease; Ethyl silicone oil is mainly used for precision instrument oil; Methylphenyl silicone oil is often used to make synthetic high-temperature lubricating grease base oil due to its high temperature resistance, low freezing point and good oxidation resistance; Chlorosilicone oil has better lubricity than other silicone oils, so it is often used to prepare base oil for medium load grease.

According to the monitoring of Baichuan Information, since the middle of February, the prices of DMC, raw rubber, 107 rubber and other basic products have bottomed out and risen, driven by the low inventory of enterprises in the domestic silicone market and the good status of downstream orders. The DMC price rose by 1.09% on February 19 after rising by 1.67% on February 18. The price in the East China market has reached 18500 yuan/ton; The market price of raw rubber in East China was 19500 yuan/ton, 500 yuan higher than that on the 18th; 107 The market price of rubber in East China was 18800 yuan/ton, up 300 yuan from the 18th. According to the analysis of Huixin, it is generally accepted by the manufacturers in the recent overhaul and during the Spring Festival
Polyether polyol is an important polymer material, which is mainly used to make various polyurethane materials. According to their different functionality, relative molecular weight and molecular structure, polyether polyols are generally divided into soft foam polyether, hard foam polyether, CASE polyether (i.e. polyether for coating, adhesive, sealant and elastomer) and POP (polymer polyether polyol) series. In recent years, with the continuous improvement of the production process, the quality of products is also improving, but the odor problem of polyether products has not been solved very well, especially the soft foam polyether polyols used in furniture, automobile, clothing and other industries,
