Polymethyl Phenyl Siloxane Fluid CS-301
Polymethyl Phenyl Siloxane Fluid CS-301
It is a colorless transparent or slightly yellow phenylmethyl polysiloxane polymer. It has high temperature resistance and special optical properties.a heat stable silicone fluid that is pourable at very low temperatures. It offers a relatively flat viscosity temperature slope, excellent dielectric properties, and resistance to the effects of most gases, salts, water, dilute alkalis, and acids.
