[Performance and application]
1. Polyethylene glycol series products can be used for pharmaceuticals. Polyethylene glycol having a relatively low molecular weight can be used as a solvent, a solubilizing agent, an o/w type emulsifier and a stabilizer, and is used for preparing a cement suspension, an emulsion, an injection, etc., and also as a water-soluble ointment base and a 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 matrix 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, reduce power consumption during processing, and extend 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, PEG-1500 used in the pharmaceutical, textile, cosmetics industry as a matrix or lubricant, softener; used as a dispersant in the coating industry; improve the water dispersibility, flexibility of the resin, the amount 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 polishing agents, 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 adjust viscosity and melting point; used 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 regulate viscosity and melting point. It is used as a lubricant and coolant in rubber and metal processing industries. It is used as a dispersant and emulsified in the industrial production of pesticides and pigments. Used as an antistatic agent, lubricant, etc. in the textile industry.
[Packing, Storage and Transportation ] PEG200, 400, 600, 800, 1000, 1500 are packed in 200kg iron drum or 50kg plastic drum; after PEG2000, 3000, 4000, 6000, 8000 slicing, 20Kg woven bag is used.
This series of products is non-toxic and non-flammable, storage and transportation according to general chemicals. Stored in a dry, well-ventilated place. The warranty period is two years. |
