1. Performance
Phenylmethyl Silicone Oil is colorless or light yellow transparent liquid. Similar to methyl silicone oil, Phenylmethyl Silicone Oil has fine insulation and ozone resistance, corona resistant performance, hydrophobic function, and small viscosity-temperature coefficient, low surface tension, shear-resistance and great compression advantages. And because of the introduction of phenylmethyl into molecular chain, Phenylmethyl Silicone Oil has better high temperature resistance, radiant resistance, lubricating property and solubility property than methyl silicone oil. The operating temperature is between -50℃ to 250℃.
2. Main Function
Phenylmethyl Silicone Oil is widely used for insulation, lubrication, damping, shock proof, moisture proof, dust proof, high temperature hydraulic oil and high temperature heat carrier. Phenylmethyl Silicone Oil is also be used as transformer filling oil and transmitter of pressure signal for various kinds of pressure transmitter.
