Polyether modified silicone oil is a kind of non-ionic surfactant with unique properties, which is made by grafting copolymerization of polyether and dimethylsiloxane. In order to meet the needs of various industries, various organosilicon surfactants with different properties can be obtained by changing the number of silicone oil chains or the ratio of polyether EO and Po and changing the number of chains and end groups.            Application 1. In plastic shed industry: it can be added into plastic as internal additive, used to produce non dripping film shed to prevent fog and improve light transmittance. 2. For fabric finishing agent: it plays a soft role, especially suitable for underwear, bedspread, towel and other finishing, not only soft, but also water absorption and sweat absorption, comfortable to wear. 3. The leveling agent used for paint and polyurethane slurry can reduce the internal friction and stress of its molecules, thus playing the role of leveling and defoaming. 4. It is used to make high-efficiency cutting fluid and high-grade cleaning agent. 5. It can be used as a foaming agent for rigid polyurethane system to make the foam pores fine and uniform. 6. This product is used in the cosmetics industry to make cream products, which has the functions of lubricating skin, moisturizing and anti wrinkle. 7. The pesticide industry is used as the wetting agent of glyphosate to improve the efficacy and reduce public hazards. 8. Polyether modified silicone oil is the key component of self emulsifying defoamer and delayed coking defoamer in oil refining industry. 9. Other new application areas not covered
