High resistance to hydrolysis and impact resistance

Polyphenyle ether is obtained from 2.6 dimethyl phenol and was previously known on the market under the name polyphenyle oxides (PPO). They characterise themselves through high heat distortion resistance, excellent dimensional stability and very low water absorbency.

With a density of 1.06 g/cm³, Polyphenylen-ether rank among the lightest engineered plastics and are applicable within a wide temperature range; mainly in electric engineering.
