The use and application field of polyethylene glycol each molecular weight
PEG-200 can be used as a medium for organic synthesis and a heat carrier with higher requirements, and can be used as a moisturizer, inorganic salt solubilizer and viscosity regulator in the daily chemical industry; Used as softening agent and antistatic agent in textile industry; Used as a wetting agent in the paper and pesticide industries.
PEG-400, PEG-600 and PEG-800 are used as substrates for medicine and cosmetics, lubricants and wetting agents for rubber industry and textile industry. PEG-600 added to electrolyte in metal industry can enhance the grinding effect and enhance the luster of metal surface.
PEG-1000 and PEG-1500 are used as substrates or lubricants and softeners in the pharmaceutical, textile and cosmetic industries; It is used as a dispersant in the coating industry to improve the water dispersion and flexibility of the resin, and the amount is 10~30%; The ink can improve the solubility of the dye, reduce its volatility, especially suitable for wax paper and printing table ink, but also can be used in the ballpoint pen ink to adjust the ink viscosity; It is used as a dispersant in rubber industry to promote vulcanization and as a dispersant for carbon black fillers.
PEG-2000 and PEG-3000 are used as metal processing casting agents, metal drawing, stamping or forming lubricants and cutting fluids, grinding cooling lubrication polishing agents, welding agents, etc.; Used in the paper industry as a lubricant, etc., but also as a hot melt adhesive to increase rapid rewetting capacity.
PEG-4000 and PEG-6000 are used as substrates in pharmaceutical and cosmetic industry to adjust viscosity and melting point; Used as finishing agent in the paper industry to increase the gloss and smoothness of paper; As an additive in the rubber industry, it increases the lubricity and plasticity of rubber products, reduces the power consumption during processing, and extends the service life of rubber products; It is used as lubricant and coolant in metal processing industry, dispersant and emulsifier in pesticide and pigment industry production; It is used as antistatic agent and lubricant in textile industry.
PEG8000 is used as a substrate in the production of medicine and cosmetics industry, which plays the role of adjusting viscosity and melting point; It is used as lubricant and coolant in rubber and metal processing industry, and as dispersant and emulsifier in pesticide and pigment industry production. It is used as antistatic agent and lubricant in textile industry.
