When applications call for a material that can stand up to prolonged heat exposure with minimal creep, Polyphenylene Oxide can provide exceptional value. Learn more about this versatile polymer below.
Polyphenylene Oxide (PPO) is an amorphous thermoplastic that is sought out for its desirable mechanical properties, including heat resistance and dimensional stability. As a true engineering thermoplastic, PPO offers a great option for challenging applications that require chronic exposure to heat, moisture, electrical current, and more.
Originally formulated in 1959 and brought to market by General Electric in 1960 as Noryl™ (now by Sabic), PPO is cost-effective for a high-temperature polymer and can be found today in applications ranging from washing machines to under-the-hood automotive parts.

An opaque thermoplastic, PPO is available in different grades depending on an application’s requirements and can be mixed with a variety of additives such as stabilizers, flame retardants, impact modifiers, and fillers. Common blends with PPO include polystyrene, high-impact polystyrene and polyamide.
PPO can be engineered to provide characteristics including:
Unless stabilized with the right additives, PPO materials may experience oxidation and damage from UV exposure over time.
