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
