1, polyethylene glycol series products can be used for pharmaceutical.
Polyethylene glycol with low relative molecular weight can be used as solvent, cosolvent,
o/w emulsifier and stabilizer for making cement suspensions, emulsions, injections, etc.,
as well as water-soluble ointment substrate and suppository substrate.
Solid waxy polyethylene glycol with high relative molecular weight is often used to increase the
viscosity and solidification of low molecular weight liquid PEG,
as well as other drugs. For drugs not easy to dissolve in water,
this product can be used as the carrier of solid dispersant,
in order to achieve the purpose of solid dispersion, PEG4000,
PEG6000 is a good coating material, hydrophilic polishing material,
film material and capsule material, plasticizer, lubricant and dripping pill matrix,
used for the preparation of tablets, pills, capsules, microcapsules and so on.
2, PEG4000, PEG6000 in the pharmaceutical industry as excipients, used as suppositories,
paste preparation; Used as finishing agent in the paper industry to increase the gloss and smoothness of paper;
In the rubber industry as an additive, increase the lubricity and plasticity of rubber products,
reduce the power consumption in the process of processing,
prolong the service life of rubber products.
3, polyethylene glycol series products can be used as raw materials of ester type surfactant.
4. PEG-200 can be used as a medium for organic synthesis and a heat carrier with higher requirements.
It is used as a moisturizing agent, inorganic salt solvator and viscosity regulator in the daily chemical industry.
Used as softener and antistatic agent in textile industry; It is 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 for rubber industry and textile industry.
PEG-600 in metal industry can be added to the electrolyte to enhance the grinding effect, enhance the luster of metal surface.
6. PEG-1000 and PEG-1500 are used as substrates or lubricants and softeners in the pharmaceutical,
textile and cosmetic industries; Used as dispersant in coating industry;
The water dispersion and flexibility of the resin were improved, and the dosage was 20~30%.
Ink can improve the solubility of dye, reduce its volatility, in wax paper and printing table ink is especially suitable,
can also be used in ballpoint pen ink for adjusting ink viscosity;
In rubber industry as a dispersant, promote vulcanization, used as a dispersant for carbon black fillers.
7, PEG-2000, PEG-3000 used as metal processing casting agent, metal drawing, stamping or forming lubricant and cutting fluid,
grinding cooling lubrication polishing agent, welding agent, etc. Used in the paper industry as a lubricant, etc.,
and also as a hot melt adhesive to increase rapid rewetting ability.
8. PEG-4000 and PEG-6000 are used as substrates in the production of medicine and cosmetics,
which play 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. Used in textile industry as antistatic agent, lubricant, etc.
9. PEG8000 is used as a matrix 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.
Used in textile industry as antistatic agent, lubricant, etc.
