Polyphynelene oxide (PPO) is impact resistant, rigid and has low moisture absorption plastic. PPO usually used as its modified version. Generally occurs in the market as 30% glass fiber reinforced, beige and black colored. PPO has high thermal resistance and could be used in wide temperature ranges. (for example -40 ºC to +140 ºC) Due to the low moisture absoption feature, the dimensional stability of the products made up from PPO is very good.
