3. Product application

Polyethylene glycol (PEG) has different specifications and application accordingly.

Polyethylene glycol (PEG-200) can be used as the medium of organic synthesis and have a higher heat carrier requirements in the chemical industry as a daily moisturizer, salt solubilizer, viscosity modifiers; in the textile industry as a softener, antistatic agent; and pesticides in the papermaking industry as a wetting agent. 


Polyethylene glycol (PEG-400, PEG-600, PEG-800) matrix for pharmaceutical and cosmetics, rubber industry and textile industry lubricants and wetting agents. PEG-600 in the metal industry in the electrolyte can be added to enhance the ground effect and enhance the luster of metal surfaces

1. Freeze protection, heat transfer and hydraulic fluids; natural gas and hydrocarbon treating agents;

2. Hydroscopic agents for paper, cork and textile conditioning;

3. Plasticizer formulations and raw materials for ester and polyester production.

4. The ethylene glycol family’s solvency properties are useful in custom formulation of paints, dyes, inks.
