PS is soluble in aromatic hydrocarbons, chlorinated hydrocarbons, aliphatic ketones and esters but can only swell . It
is resistant to some mineral oils, organic acids, bases, salts, lower alcohols and their aqueous solutions. It has low water
absorption and can maintain its mechanical properties and dimensional stability in humid environment. Excellent electrical
performance, volume resistance and surface resistance are high, and is not affected by temperature, humidity changes, also not
affected by corona discharge. Radiation resistance is also very good
