Performance and application
| SPEC. | Performance and application |
| S-20 | 1.Soluble in oil and organic solvents, dispersed in water as a semi-emulsion liquid.
2.In the production of medicine and cosmetics, W/O emulsifiers, stabilizer, plasticizer, lubricants, and desiccants. Used as softener, antistatic agent, and finishing agent in the textile industry. It is also used as a mechanical lubricant. As an additive antifog agent, it has good initial and low- temperature anti- fog droplet properties and is suitable for PVC (1~1.5%), polyolefin film (0.5~0.7%), and EVA film. |
| S-40 | 1.Soluble in oil and organic solvents, dispersed in hot water.
2. As an emulsifier and dispersant in the food and cosmetics industry. Emulsion stabilizer in emulsion polymerization. Dispersant in printing ink. It can also be used as a textile waterproof coating additive, oil emulsion, and dispersant. Widely used in polymer anti-fog drops, PVC agricultural film 1~1.7%, EVA 0.5~0.7%. |
| S-60 | 1.This product is insoluble in water and dispersed in hot water. It is a good w/o emulsifier with strong emulsification, dispersion, and lubrication properties, as well as a good stabilizer and defoamer.
2. Used as an emulsifier in the food industry, used in the production of beverages, toffee, ice cream, bread, cakes, malted milk, margarine, chocolate, etc. Used as an antistatic agent and soft oiling agent for acrylic fibers in the textile industry components. Used as emulsifiers and stabilizers in food, pesticides, medicine, cosmetics, coatings, and plastics industries. Used as anti- -fog drops for PVC, EVA, PE, and other films, the dosage in PVC is 1.5~ 1.8%, and the dosage in EVA is 0.7~ 1%. |
| S-80 | 1. Insoluble in water, soluble in hot oil and organic solvents, is a high-grade lipophilic emulsifier.
2. Used for W/O latex explosives, nylon, and viscose cord oil, which has a good smoothing effect on fibers. It is used for the emulsification of machinery, coatings, chemicals, and explosives. As an emulsifier in oil drilling weighted mud，as an emulsifier in the production of food and cosmetics，and as a dispersant in the paint and coating industry. Used as a stabilizer in the production of titanium dioxide，insecticides, wetting agents, and emulsifiers in pesticide production. As a CO- solvent in petroleum products; It can also be used as a rust inhibitor for anti-rust oil. Lubricants and softeners for textiles and leather. 3. As a film anti-fog dropper, it has good initial and low- temperature anti-fog droplet properties, and the dosage in PVC is 1~1.5%, and the dosage in polyolefin is 0.5~0.7%. |
| S-85 | 1. Slightly soluble in isopropanol, tetrachloroethylene, cotton oil, etc.
2. Mainly used in medicine,cosmetics, textile, paint, and petroleum industries, etc., used as emulsifiers, thickeners, rust inhibitors, etc |
