The NORYL family of modified PPE resins consists of amorphous blends of PPO? resin (polyphenylene ether) and polystyrene. They combine the inherent benefits of PPO resin (affordable high heat resistance, good electrical properties, excellent hydrolytic stability and the ability to use non-halogen FR packages), with excellent dimensional stability, good processibility and low specific gravity.
NORYL resins offer a good balance of mechanical and chemical properties, and may be suitable for a wide variety of applications
