Performance and Application

1. Use as low-foaming detergent or defoaming agent

L61, L64, and F68 are used to prepare low-foaming, high-detergency synthetic detergents;

L61 is used as a defoaming agent in papermaking or fermentation industries;

F68 is used as a defoaming agent during blood circulation in artificial heart-lung machines to prevent air from entering.

2. Polyether has very low toxicity and is often used as pharmaceutical excipients and emulsifiers; it is often used in oral and nasal sprays, eye and ear drops and shampoos.

3. Polyether is an effective wetting agent and can be used in acidic conditions for fabric dyeing, photographic development and electroporation. When using F68 in sugar factories, more sugar can be obtained due to the increased water permeability.

4. Polyether is a useful antistatic agent, and L44 can provide long-lasting electrostatic protection for synthetic fibers.

5. Polyether is used as a dispersant in emulsion coatings. F68 is used as emulsifier in vinyl acetate emulsion polymerization. L62 and L64 can be used as pesticide emulsifiers, coolants and lubricants in metal cutting and grinding. Used as a lubricant when rubber is vulcanized.

6. Polyether can be used as crude oil demulsifier. L64 and F68 can effectively prevent the formation of hard scale in oil pipelines and be used for the recovery of secondary oil.

7. Polyether can be used as papermaking additives, and F68 can effectively improve the quality of coated paper.

8. F38 can be used as emulsifier, wetting agent, defoaming agent, demulsifier, dispersant, antistatic agent, dust remover, viscosity regulator, foam control agent, leveling agent, gelling agent, etc. for production Agricultural chemicals, cosmetics, pharmaceuticals; also used in metal processing cleaning, pulp and paper industry, textile processing (textile, finishing, dyeing, softening finishing), water quality treatment; also used as a rinse aid.

9. P65 is mainly used in the wool spinning industry. As a wool protective agent, adding about 0.3% in the wool carbonization process can reduce wool scale damage, enhance single fiber strength by 10%, and reduce spinning breakage rate by 10%.
