Performance & Applications
Specs | Performance and Specifications |
| S-20 | 1. Soluble in oils and organic solvents; disperses in water as a semi-galactose liquid. 2. Used as a W/O emulsifier, stabilizer, plasticizer, lubricant, and desiccant in pharmaceutical and cosmetic production; as a softener, antistatic agent, and finishing agent in the textile industry; also serves as a mechanical lubricant. As an additive anti-fog agent, it exhibits excellent initial and low-temperature anti-fogging properties, suitable for PVC (1~1.5%), polyolefin film (0.5~0.7%), and EVA film. |
S-40 | 1. Soluble in oils and organic solvents, it disperses in hot water. 2. Used as an emulsifier and dispersant in the food and cosmetics industry; as an emulsifying stabilizer in liquid polymerization; as a dispersant in printing inks; also serves as an additive for textile waterproof coatings and oil emulsifying dispersants; widely used in polymer anti-dew agents, with PVC agricultural film at 1~1.7%, and EVA at 0.5~0.7%. |
S-60 | 1. This product is insoluble in water, forming a dispersed state in hot water. It is an excellent w/o emulsifier with strong emulsifying, dispersing, and lubricating properties, and also serves well as a stabilizer and defoamer. 2. Used as an emulsifier in the food industry, applicable in the production of beverages, sugar candies, ice cream, bread, cakes, malted milk, butter, chocolate, etc.; in the textile industry, as an antistatic agent and softening lubricant component for acrylic fibers; as an emulsifier and stabilizer in the food, agricultural pesticide, pharmaceutical, cosmetic, coating, and plastic industries; and as a fogging inhibitor for PVC, EVA, PE, and other film products, with usage rates of 1.5-1.8% in PVC and 0.7-1% in EVA. |
S-80 | 1. Insoluble in water, soluble in hot oil and organic solvents; it is a high-grade oleophilic emulsifier. 2. Used for W/O type rubber explosive, nylon and viscose帘子线 oiling agent, which has a good smoothing effect on fibers. Suitable for emulsification in machinery, coatings, chemicals, and explosives. Acts as an emulsifier in heavy mud for oil drilling; used as an emulsifier in food and cosmetic production; as a dispersant in the paint and coatings industry; as a stabilizer in titanium dioxide production; as an insecticide, wetting agent, and emulsifier in pesticide production; as a solvent aid in petroleum products; and also as a rust inhibitor for anti-rust oils. Also serves as a lubricant and softener for textiles and leather. 3. As a film antifogging agent, it exhibits excellent initial and low-temperature antifogging properties. The dosage in PVC is 1~1.5%, and in polyolefins, it is 0.5~0.7%. |
S-85 | 1. Slightly soluble in isopropyl alcohol, tetrachloroethylene, cottonseed oil, etc. 2. Primarily used in the pharmaceutical, cosmetics, textile, paint, and petroleum industries, serving as emulsifiers, thickeners, rust inhibitors, and more. |
