We can produce 200,000 tons of chemical fiber oil and 200,000 tons of surfactants annually. We can supply more than one hundred types of products. Especially its polyester POY oil is an exclusively developed product in China and can totally replace imported hi-tech products.
Polyethylene glycol (PEG) is a class of linear polyether compounds produced by the addition polymerisation of ethylene oxide. Its CAS number is 25322-68-3.
PEG exhibits a range of molecular weights and physical states. Low molecular weight PEG (below 200 molecular weight) typically presents as a colourless, transparent liquid with good fluidity; medium to high molecular weight PEG appears waxy or solid, with melting points increasing with molecular weight.
PEG is non-toxic, non-irritating, and non-corrosive. It dissolves readily in polar solvents such as water and ethanol, exhibiting excellent lubricity, moisturising properties, dispersibility, and solubilising capabilities. It also demonstrates good compatibility with numerous chemical agents.
Owing to its high biocompatibility and chemical stability, it finds extensive application across pharmaceuticals, cosmetics, foodstuffs, textiles, papermaking, rubber, and coatings industries.
In pharmaceuticals, it serves as a matrix, drug carrier, and controlled-release agent; in cosmetics, it functions as a humectant, solvent, and emulsifier; and in industrial applications, it acts as a lubricant, plasticiser, antistatic agent, dispersant, and release agent.
PEGs of different molecular weights exhibit distinct physical properties and application scenarios. Here Hengxiang mainly has Polyethylene glycol 200, Polyethylene glycol 300, Polyethylene glycol 400, Polyethylene glycol 600, Polyethylene glycol 800 and Polyethylene glycol 1000.
Polypropylene glycol is a class of linear or branched polyether compounds polymerised from propylene oxide. CAS number 25322-69-4 is the official registration number for polypropylene glycol, used to identify its chemical structure and purity.
Hengxiang mainly has Polypropylene glycol 200, Polypropylene glycol 400, Polypropylene glycol 600 and Polypropylene glycol 1000.
PPG exhibits low toxicity, excellent biocompatibility, and chemical stability, demonstrating resistance to hydrolysis, acids, and alkalis. It possesses good solubility, particularly showing outstanding affinity in organic solvents and certain oils. Its unique chemical properties render it a multifunctional industrial raw material, serving as a polyol component in polyurethane foam production, a lubricant, dispersant, and defoamer, as well as an emulsifier and softener in textiles, coatings, metalworking, and cosmetics industries.
Low molecular weight PPG is commonly employed in liquid formulations and cosmetics, whilst high molecular weight PPG serves as a thickener, emulsifier, or polymer modifier.
