performance and application
|
|
S-20
|
1, soluble in oil and organic solvents, dispersed in water was semi emulsion liquid.
2, in the pharmaceutical and cosmetics for the production of W/O emulsifier, stabilizer, plasticizer, lubricant, desiccant; as softening agent, antistatic agent, finishing agent in textile industry; also used as a lubricant; as an added anti fog agent, has good anti fog and low temperature stage, suitable for PVC (1 ~ 1.5%) and polyolefin film (0.5 ~ 0.7%), EVA film.
|
|
S-40
|
1, soluble in oil and organic solvents, hot water in a dispersed.
2, food and cosmetics industry as emulsifier, dispersant; emulsion polymerization in emulsion stabilizer; dispersing agent in printing ink; can also be used as textile waterproofing coating additives, oil emulsion dispersing agent; antifogging agents are widely used in polymer PVC film, 1 ~ 1.7%, EVA0.5 ~ 0.7%.
|
|
S-60
|
1, this product is not soluble in water, is dispersed in hot water is good w/ o emulsifier, has strong emulsification, dispersion, lubrication, stabilizer and defoaming agent is good.
2, in the food industry as emulsifiers, for drinks, candy, ice cream, bread, cakes, chocolate malted milk, margarine, etc. in the production of acrylic fiber; used as antistatic agent, softening agent oil components in the textile industry; in food, pesticides, medicine, cosmetics, paint and plastic industry used as emulsifier and stabilizer; antifogging agents using PVC, EVA, PE film, PVC dosage is 1.5 ~ 1.8%, in EVA was 0.7 ~ 1%.
|
|
S-80
|
1, insoluble in water, soluble in hot oil and organic solvent, high lipophilic emulsifier.
2, for the W/O type emulsion explosive, polyamide and viscose cord oil, has a good smoothing effect on fiber. For mechanical, coating, chemical, explosive emulsion. In oil drilling mud aggravated as emulsifier; food and cosmetics production as emulsifier; dispersing agent paint and coatings industry for the production of titanium dioxide; stabilizer; pesticide production as pesticides, wetting agent and emulsifier; cosolvent for petroleum products; can also be used as anti rust agent anti rust oil. Lubricant and softening agent for textile and leather.
3, as the film has good antifogging agents, low temperature and initial antifogging, in PVC was 1~1.5%, the dosage of 0.5~0.7% in polyolefin.
|
|
S-85
|
1, slightly soluble in isopropyl alcohol, four vinyl chloride, cottonseed oil etc..
2, mainly used in medicine, cosmetics, textile, paint and oil industry, etc., used as emulsifier, thickener, anti rust agent, etc..
