【Performance and Application】
1. Polyethylene glycol series products can be used in pharmaceuticals. Polyethylene glycol with relatively low molecular weight can be used as solvent, cosolvent, o/w type emulsifier and stabilizer, used to make cement suspension, emulsion, injection, etc., and also used 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 external compensation of other drugs; For the purpose of solid dispersion, PEG4000 and PEG6000 are good coating materials, hydrophilic polishing materials, film materials and capsule materials, plasticizers, lubricants and dropping pill 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 finishing agents in the paper industry to increase the gloss and smoothness of paper; as additives in the rubber industry to increase the lubrication of rubber products It reduces power consumption during processing and prolongs 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 moisturizing agent, inorganic salt solubilizer and viscosity regulator in the daily chemical industry; Static agent; used as a wetting agent in the paper and pesticide industries.
5. PEG-400, PEG-600 and PEG-800 are used as substrates for medicine and cosmetics, lubricants and wetting agents in rubber industry and textile industry. Adding PEG-600 to the electrolyte in the metal industry can enhance the grinding effect and enhance the luster of the metal surface.
6. PEG-1000 and PEG-1500 are used as substrates or lubricants and softeners in the pharmaceutical, textile and cosmetic industries; they are used as dispersants in the coating industry; to improve the water dispersibility and flexibility of resins, the dosage is 20~ 30%; In ink, it can improve the dissolving ability of dyestuff and reduce its volatility. It is especially suitable for wax paper and ink pad ink. It can also be used to adjust ink viscosity in ballpoint pen ink. It is used as dispersant in rubber industry to promote vulcanization. It is used as a dispersant for carbon black fillers.
7. PEG-2000 and PEG-3000 are used as metal processing casting agents, lubricants and cutting fluids for metal drawing, stamping or forming, grinding and cooling lubricant polishing agents, welding 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 industrial production of medicine and cosmetics to adjust viscosity and melting point; they are used as lubricants and coolants in the rubber and metal processing industries, and in the industrial production of pesticides and pigments. Used as dispersant and emulsifier; used as antistatic agent, lubricant, etc. in textile industry.
9. PEG8000 is used as a matrix in the pharmaceutical and cosmetic industries to adjust viscosity and melting point; it is used as a lubricant and coolant in the rubber and metal processing industries, and as a dispersant and emulsifier in the industrial production of pesticides and pigments. agent; used as antistatic agent, lubricant, etc. in the textile industry.
【Packaging and Storage】
PEG200, 400, 600, 800, 1000, 1500 are packed in 200kg iron drums or 50kg plastic drums; PEG2000, 3000, 4000, 6000, 8000 are sliced and packed in 20Kg woven bags.
