Silicone rubber is generally considered to be nonpolar. Its molecular structure, which includes silicon-oxygen bonds, leads to a low polarity, making it hydrophobic and resistant to water absorption. This nonpolar characteristic contributes to silicone rubber's excellent flexibility, durability, and thermal stability.
Rubber is considered nonpolar because it is composed mainly of hydrocarbons which have symmetrical molecular structures. This symmetry leads to an even distribution of charge and no distinct positive or negative areas, resulting in a nonpolar molecule.

Phenol is not miscible in silicone oil. Phenol is a polar compound, while silicone oil is nonpolar. This difference in polarity makes them immiscible in each other.
Nonpolar
The polarity of rubber is determined by the presence or absence of polar functional groups in its molecular structure. These functional groups can create regions of uneven charge distribution within the molecule, resulting in a polar nature. Rubber, being a nonpolar polymer made mostly of carbon and hydrogen atoms, is generally considered nonpolar.
