Phenyl Methyl Silicone Oil IOTA255 is colorless transparent liquid. Compared with Dimethyl silicone oil, it has better performance in high and low temperatures (-70 ~ 300°C ), and better properties of lubricity, mold unloading and electrical insulation. It is small in temperature viscosity coefficient and volatility. Compression rate and the surface tension is high. It is well in miscibility with other organic resin. The UV-resistant properties is unique.
