Polyethylene glycol series products can be used for pharmaceuticals. Polyethylene glycol with relatively low molecular weight can be used as solvent, co-solvent, o/w emulsifier and stabilizer for making cement suspension, emulsion, injection, etc., and also as water-soluble ointment base and suppository base. Solid waxy polyethylene glycol with high relative molecular weight is often used to increase the viscosity and solidity of low molecular weight liquid PEG, as well as externally compensated other drugs; for drugs that are not easily soluble in water, this product can be used as a carrier for solid dispersant to achieve For solid dispersion purposes, PEG4000, PEG6000 are good coating materials, hydrophilic polishing materials, membranes and capsules, plasticizers, lubricants and dropping pills bases for the preparation of tablets, pills, capsules, microcapsules. Wait. 2. PEG4000 and PEG6000 are used as excipients in the pharmaceutical industry for the preparation of suppositories and ointments; as a finishing agent in the paper industry, to increase the gloss and smoothness of paper; as an additive in the rubber industry, to increase the lubrication of rubber products Sex and plasticity, reducing power consumption during processing and prolonging the service life of rubber products. 3. Polyethylene glycol series products can be used as raw materials for ester surfactants. 4. PEG-200 can be used as a medium for organic synthesis and a heat carrier with high requirements. It is used as a moisturizer, inorganic salt solubilizer and viscosity modifier in the daily chemical industry; as a softener and anti-wear in the textile industry. Electrostatic agent; used as a wetting agent in the paper and pesticide industry. 5, PEG-400, PEG-600, PEG-800 used as a substrate for medicine and cosmetics, lubricants and wetting agents for the rubber industry and the textile industry. PEG-600 is added to the electrolyte in the metal industry to enhance the grinding effect and enhance the gloss of the metal surface. 6. PEG-1000 and PEG-1500 are used as matrix or lubricant and softener in medicine, textile and cosmetics industries; as dispersant in coating industry; improve water dispersibility and flexibility of Resin, dosage is 20~ 30%; the ink can improve the solubility of the dye and reduce its volatility. It is especially suitable for use in wax paper and printing pad ink. It can also be used to adjust the ink viscosity in ballpoint pen ink. It is used as a dispersant in the rubber industry to promote vulcanization. Function, used as a dispersant for carbon black filler. 7. PEG-2000 and PEG-3000 are used as metal processing molds, metal wire drawing, stamping or forming lubricants and cutting fluids, grinding and cooling lubricants, soldering agents, etc.; used as lubricants in the paper industry, etc. Used as a hot melt adhesive to increase rapid rewetting. 8. PEG-4000 and PEG-6000 are used as substrates in the production of pharmaceutical and cosmetic industries to regulate viscosity and melting point; as lubricants and coolants in rubber and metal processing industries, in the production of pesticides and pigments. Used as a dispersant, emulsifier; used as an antistatic agent, lubricant, etc. in the textile industry. 9. PEG8000 is used as a matrix in the production of pharmaceutical and cosmetic industries to adjust viscosity and melting point. It is used as a lubricant and coolant in rubber and metal processing industries. It is used as a dispersing agent and emulsification in the industrial production of pesticides and pigments. Agent; used as an antistatic agent, lubricant, etc. in the textile industry. 【Packing and Storage】 PEG200, 400, 600, 800, 1000, 1500 are packed in 200kg iron drum or 50kg plastic drum; PEG2000, 3000, 4000, 6000, 8000 are sliced and packed in 20Kg woven bag.
