Chemical Structure:
Phenyl Methyl Silicone Oil TPD-255 is a colorless transparent liquid. Because of the phenyl group on the polymer chain, it has excellent radiation, oxidation and temperature resistance.
Features
- Excellent resistance to high and low tempratures (-40 ~ 300°C)
- Low volatility
- Excellent heat transfer characteristics
- Flat viscosity temperature curve
- Good compressibility
- Good oxidation and radiation resistance
- Good miscibility with organic resin
