Polyethylene Glycol
Polyethylene glycol is referred to as “PEG”. It is a high molecular weight compound formed by dehydration condensation of ethylene glycol molecules. The chemical formula is HOCH2(CH2OCH2)nCH2OH. Where n is greater than 4. The average molecular weight is 200-7000. The number after the commercial polyethylene glycol indicates the average molecular weight. For example, polyethylene glycol-400 means that the average molecular weight of the commercial polyethylene glycol is about 400.Read more -
Choline chloride
Choline chloride was developed by the Agricultural Technology Institute of the Ministry of Agriculture, Forestry and Fisheries of Japan in 1964, and registered as a plant growth regulator in 1987. It also became vitamin B4. Common choline chlorides on the market are divided into plant-carrier choline chloride and white carbon black (silicon dioxide) as a carrier choline chloride. my country’s production is about 400,000 tons, accounting for more than 50% of the global production capacit...Read more -

Mesitylene
Mesitylene (also known as 1,3,5-trimethylbenzene, molecular formula C9H12) has a molecular structure in which the C atoms of the benzene ring form σ bonds with sp2 hybrid orbitals, and the other C atoms form σ bonds with sp3 hybrid orbitals. It is a functional group present in many organic compounds. It is an aromatic hydrocarbon obtained by symmetrically replacing three hydrogen atoms on the benzene ring with three methyl groups. It is widely present in coal tar and some petroleum. It is a c...Read more -
Pyromellitic Dianhydride
The English name of pyromellitic dianhydride is Pyromellitic Dianhydride (abbreviated as PMDA, the same below), which is mainly used to synthesize polyimide. Since polyimide has excellent ultra-high heat resistance, acid and alkali resistance, excellent mechanical properties, electrical properties and dimensional stability, it is widely used in high-tech fields such as aviation, aerospace, microelectronics and atomic energy that have strict requirements on material properties.Read more -
1,2,4,5-Tetramethylbenzene
Properties: Durene, also known as 1,2,4,5-tetramethylbenzene, is an organic compound with a chemical formula of C6H2(CH3)4. It is a colorless solid with a sweet odor.
