Properties and Application]
1, polyethylene glycol can be used in pharmaceutical products. Relatively low molecular weight polyethylene glycol can be used as solvent, cosolvent, o/w emulsifier and stabilizer for the production of cement suspension, emulsions, injections, etc., is also used as a water-soluble ointment base and suppository bases, relatively high molecular weight solid waxy polyethylene glycol commonly used to increase the viscosity of the low molecular weight PEG liquid and a solid, as well as outside compensation other drugs; water for poorly soluble drugs can be used as a carrier of solid dispersant to achieve solid dispersion purposes, PEG4000, PEG6000 are good coating materials, hydrophilic polishing materials, membranes and wall materials, plasticizers, lubricants and dropping pills matrix for tablets, pills, capsules, microcapsules Wait.
2, PEG4000, PEG6000 excipient used in the pharmaceutical industry suppositories, prepared as a paste; used as a coating agent for paper industry, increase paper gloss and smoothness; in the rubber industry as an additive to increase the lubrication of rubber products and plasticity, reduce processing power consumption and extend the life of rubber products.
3, polyethylene glycol can be used as raw material ester surfactant.
4, PEG-200 can be used as organic synthesis of medium and higher requirements for heat carrier, is used as a humectant in daily chemical industry, inorganic salt solubilizers, viscosity modifiers; used as a softener in the textile industry, anti- static agent; paper and used as a wetting agent in the pesticide industry.
5, PEG-400, PEG-600, PEG-800 matrix for medicine and cosmetics, lubricants and wetting agents rubber industry and textile industry. PEG-600 was added in the metal industry in the electrolyte can enhance the grinding effect, enhanced gloss metal surface.
Packaging and Storage
PEG200,400,600,800,1000,1500 uses 200kg drum or 50kg plastic drum; PEG2000,3000,4000,6000, adopted after the 8000 slice 20Kg woven bag.
This series of products non-toxic, non-flammable, as a general chemical storage and transportation. Store in a dry ventilated place. Shelf life of two years.
