Performance and Application
—
Low-Foam Detergent or Defoamer
L61, L64, F68: Used to formulate low-foam, high-detergency
synthetic detergents.
L61: Used as a defoamer in the paper or fermentation industries.
F68: Used as a defoamer in blood circulation during artificial
heart-lung machine operations to prevent air entry.
Pharmaceutical Excipients and Emulsifiers:
Due to their low toxicity, polyethers are commonly used as
excipients and emulsifiers in pharmaceuticals, including oral,
nasal sprays, eye and ear drops, and shampoos.
Wetting Agents:
Effective wetting agents used in fabric dyeing, photographic
development, and acidic baths for electroplating. F68 increases
water permeability in sugar factories, leading to higher sugar
yields.
Antistatic Agents:
L44: Provides lasting antistatic protection for synthetic fibers.
Dispersants in Emulsion Coatings:
F68: Used as an emulsifier in the polymerization of vinyl acetate
emulsions.
L62, L64: Used as pesticide emulsifiers, coolants, and lubricants
in metal cutting and grinding, and lubricants in rubber
vulcanization.
Crude Oil Demulsifiers:
L64, F68: Effectively prevent scale formation in oil pipelines and
are used in secondary oil recovery.
Paper Additives:
F68: Enhances the quality of coated paper.
Various Applications:
F38: Used as emulsifiers, wetting agents, defoamers, demulsifiers,
dispersants, antistatic agents, dust control agents, viscosity
modifiers, foam control agents, leveling agents, and gelling
agents. Applicable in agricultural chemicals, cosmetics,
pharmaceuticals, metalworking cleaning, pulp and paper industries,
textile processing (weaving, finishing, dyeing, soft finishing),
water treatment, and as bleaching assistants.
Wool Industry:
P65: Mainly used in the wool industry as a wool protector. Adding
approximately 0.3% during wool carbonization reduces wool scale
damage, increases single fiber strength by 10%, and reduces yarn
breakage rate by 10%.
