Polydimethylsiloxane for Cosmetics and Personal Care Tire Polish Silway 520

Silway 520 is a polydimethylsiloxane polymer manufactured to yield essentially linear polymers in a wide range of average kinematic viscosities. Silway 520 is colorless, transparent, odourless and non-toxic oil liquid. The viscosity increases with the added of n value of Si-O chain, from highly mobile liquid to thick semisolid.   Typical ApplicationsMachineTextile Paint Personal Care Pharma   UsageAs DefoamerDue to the feature of low surface tension, insoluble, and chemical stability, Silway 520 is used as defoamer/antifoamer in petrochemical industry, medical industry, pharmaceutical industry, food processing, texture, printing and dyeing, paper industry, etc. As Lubricant As lubricant, Silway 520 is suitable for rubber, plastic bearings, and gears. Also be proper for rolling friction between steel materials to steel or other metals under high temperature. Remarkable: In general case, Dimethyl silicone oil is not suggested as lubricant between metals in room temperature. As Mold Release Agent Due to the non-stick ability on rubber, plastic and metal, etc., Silway 520 is often used as mold releasing agent during molding process of rubbers and plastic products. As mold releasing agent, Silway 520 not only demold easily, but leaves clean, smooth,and clear grain on the surface of products. As coating of Insulation, dust/mould proof Applying a coat of Silway 520 on the surface of glass or ceramics, then making heat treating by 250-300ºC, a semi permanent waterproof, mould proof and insulation membrane.   Key FeaturesEase of application and ruboutEnhances color High water repellency High spreadability and compatibility Low environmental hazard Essentially odorless, tasteless and nontoxic   Typical Physical Properties  Index itemViscosity (cst, 25ºC)Special Gravity (25ºC)Flash point  (ºC, ≥)Pour Point (ºC)520-1001000.962-0.972260-55520-3503500.965-0.975320-55520-5005000.965-0.975320-50520-100010000.967-0.975320-50520-12500125000.967-0.975320-25520-60000600000.978-0.979321-25Packing 200L or IBC drumsStorage Storage in closed containersShelf Life 36 months   /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
