[Performance and Application] 1. 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. Polyethylene glycol series products can be used as raw materials for ester surfactants. 3, PEG-200 can be used as a medium for organic synthesis and a hot 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. 4, 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. 5, PEG-1000, PEG-1500 used as a matrix or lubricant, softener in the pharmaceutical, textile, cosmetics industry; used as a dispersant in the coating industry, improve the water dispersibility and flexibility of the resin, the dosage is 10~ 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. 6. PEG-2000 and PEG-3000 are used as metal processing molds, metal wire drawing, stamping or forming lubricants and cutting fluids, grinding and cooling polishing agents, soldering agents, etc.; used as lubricants in the paper industry, etc. Used as a hot melt adhesive to increase fast rewetting ability. 7. PEG-4000 and PEG-6000 are used as substrates in the production of pharmaceutical and cosmetic industries to adjust the viscosity and melting point; 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 lubricity and plasticity of rubber products, reduce the power consumption during processing, and prolong the service life of rubber products; use as a lubricant and coolant in the metal processing industry, as a dispersant in the production of pesticides and pigments, Emulsifier; used as an antistatic agent, lubricant, etc. in the textile industry. 8. PEG8000 is used as a substrate 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, Storage and Transportation] PEG200, 400, 600, 800, 1000, 1500, 2000, 3000 are packed in 200kg iron drum or 50kg plastic drum; PEG4000, 6000, 8000 are sliced and packed in 20Kg woven bag. This series of products is non-toxic, non-flammable, and stored and transported as general chemicals. Store in a dry, well-ventilated place. The warranty period is two years.
