While many amorphous thermoplastics lose strength at elevated temperatures, Noryl PPO retains its rigidity, impact strength and dimensional stability — even at 230°F continuous use. This balance of properties, coupled with inherent moisture and chemical resistance, makes it ideal for a wide range of electrical insulation components.

​

For added strength and stiffness, Noryl PPO can be reinforced with glass fiber fill. The material is easily machined, available in stock shapes, and can be thermoformed.
