UPS F.303
SILICONE OIL 350
UPS F.303 Silicone Oil 350 is a group of transparent dlmethyl silicone fluids with a range of viscosity from 0,85 to 1,000,000 cantstrokes. They are used in many branches of industry because of some outstanding properties: small change of viscosity, high order of thermal oxidative stability, high resistance to shear breakdown, high compressibility, excellent water repellency, high order of chemical and physiological inertness and non-stick characteristics.
