Performance & Applications
1. Used as low-foaming detergents or defoamers. L31, L61, L64, L81, P84, F68 are used to formulate low-foaming, high-efficiency synthetic detergents; L31, L61, L81 are used as defoamers in the papermaking or fermentation industry; F68 is used as a defoamer during artificial lung machine blood circulation to prevent air from entering.
2. Polyether has low toxicity 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 dyeing fabrics, photographic development, and acidic baths for electroplating. In sugar factories, the use of F68 increases water permeability, leading to a higher yield of sugar.
4. Polyether is an effective antistatic agent, and L44 offers long-lasting antistatic protection for synthetic fibers.
5. Polyether serves as a dispersant in emulsion coatings. F68 acts as an emulsifier during the polymerization of vinyl acetate emulsion. L62, L64, and L81 can be used as coolants and lubricants in metal cutting and grinding. They also function as lubricants during rubber curing.
6. Polyether can be used as crude oil demulsifier, and L64, F68, P84 effectively prevent the formation of hard scale in oil pipelines and are also used in the recovery of secondary oil.
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 collector, viscosity regulator, foam control agent, leveling 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 it serves as a clarification 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鳞片 damage and increase the strength of individual fibers by 10%, as well as decrease the breakage rate of yarn by 10%.
10. L64 and P84 can be used as emulsifiers for pesticides. The products formulated have stable quality and do not deteriorate within the effective storage period. They exhibit good emulsifying properties, are suitable for a variety of pesticide types, require minimal quantities, and can produce high-concentration formulations. They have good miscibility with the active ingredient and solvents.
11. Alternative Imported PE Product Series.
