Performance and application:

1. As a low-foam detergent or defoamer, L61, L64, F68 are used to prepare low-foam, high- detergent synthetic detergents. L61 is used as a defoamer in the paper or fermentation industry. F68 is used as a defoamer during blood circulation in an artificial heart-lung machine to prevent air from entering.

2. Polyether has very low toxicity and is often used as a drug excipient and emulsifier. It is often used in the mouth, nasal sprays, eyes drops, ear drops, and shampoos.
3. Polyether is an effective wetting agent, can be used for fabric dyeing, photographic development and electric crossing acid margin. More sugar can be obtained in the sugar factory using F68 due to increased water permeability.

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

5. Polyether is used as a dispersant in emulsion coating. F68 is used as an emulsifier during the polymerization of polyvinyl acetate emulsion. L62 and L64 can be used as pesticide emulsifiers, coolants and lubricants in metal cutting and grinding. It is used as a lubricant when rubber is vulcanized.

6. Polyether can be used as crude oil demulsifier. L64 and F68 can prevent the hard-scale formation in oil pipelines and recover secondary oil.

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

8. F38 can be used as an emulsifier, wetting agent, defoamer, demulsifier, dispersant, antistatic agent, dust collector, viscosity modifier, foam control agent, leveling agent, gelling agent, etc., for the production of agricultural chemicals, cosmetics, drugs, it is also used in metal processing and cleaning, pulp and paper industry, textile processing (textile, finishing, dyeing, soft finishing), water quality treatment. It is also used as a bleaching aid.

9. P65 is mainly used in the wool industry, as a wool protection agent. Adding about 0.3% to the wool carbonization process can reduce wool scale damage, enhance the strength of single fiber by 10%, and reduce the yarn breakage rate by 10%.
