Performance and Applications

    1. Low-foaming detergent or defoamer

    L61, L64, and F68 are used for preparing low-foaming, high-detergent synthetic detergents.

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

    F68 acts as a defoaming agent during the artificial lung machine's blood circulation, preventing air from entering.

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

    3. Polyether is an effective wetting agent, used in acidic baths for fabric dyeing, photographic developing, and electroplating. In sugar factories, the use of F68 increases water permeability, resulting in higher sugar yields.

    4. Polyether serves as an effective antistatic agent, with L44 providing long-lasting antistatic protection for synthetic fibers.

    5. Polyether acts as a dispersant in emulsion coatings. F68 serves as an emulsifier during the polymerization of vinyl 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 scales 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, gelling agent, 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, increase the strength of individual fibers by 10%, and lower the yarn breakage rate by 10%.
