In terms of physical properties, the difference between methyl silicone resin and phenyl silicone resin is also obvious. Due to the strong polarity of phenyl group, phenyl silicone resin has greater polarity and is more compatible with polar materials. Methyl silicone resin has lower polarity due to the weak polarity of methyl group. In addition, phenyl silicone resins generally have higher heat resistance and can maintain stability at higher temperatures. Methyl silicone resins may show better flexibility and processing performance at lower temperatures.
