Performance & Applications

1. Low-foaming detergent or defoamer


L61, L64, F68 are used to formulate low-foaming, high-detergency synthetic detergents.


L61 is used as a defoaming agent in the papermaking or fermentation industry.


F68 is used as a defoaming agent during the artificial lung machine's blood circulation, to prevent air from entering.


2. Polyether toxicity is very low and is commonly used as a pharmaceutical excipient and emulsifier; it is frequently employed in oral sprays, nasal sprays, eye and ear drops, as well as shampoos.

3. Polyether is an effective wetting agent, used in the acidic baths for fabric dyeing, photographic development, and electroplating. At sugar factories, the use of F68 increases water permeability, allowing for more sugar extraction.

4. Polyether is an effective antistatic agent, L44 provides long-lasting antistatic protection for synthetic fibers.

5. Polyether acts as a dispersant in emulsion paints. F68 serves as an emulsifier during the polymerization of ethylene acetate emulsion. L62 and L64 can be used as emulsifiers for pesticides, and as coolant and lubricant in metal cutting and grinding. They also function as lubricants during rubber vulcanization.


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


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


8. F38 can be used as an emulsifier, wetting agent, defoamer, demulsifier, dispersant, antistatic agent, dust remover, viscosity regulator, foam control agent, dyeing agent, and gelatinizer, etc., for the production of agricultural chemicals, cosmetics, and pharmaceuticals; it is also used in metal processing cleaning, pulp and paper industry, textile processing (spinning, finishing, dyeing, softening), and water treatment; and serves as a bleaching aid.


9. P65 is primarily used in the woolen textile industry as a wool protector. Adding approximately 0.3% during the wool carbonization process can reduce wool scale damage, enhance the strength of individual fibers by 10%, and decrease the yarn breakage rate by 10%.
