Polyphenylene Oxide / Polyamide Alloy - PPO/Nylon Alloy - PPO/PA Alloy

Polymer Type

Thermoplastic

Advantages

Better resistance to hydrocarbons than PPO, and has the ability to be painted.

Disadvantages

Higher water absorption than PPO due to Nylon content.  Poorer electrical properties than PPO.
