A Practical Guide to NORYL Resin Grades and Applications
NORYL is a family of modified polyphenylene ether (PPE) resins. These blends of PPE and polystyrene deliver a strong balance of properties: affordable high heat resistance, excellent electrical insulation, hydrolytic stability, and compatibility with non-halogenated flame retardants, all within a low-density material.
The following sections break down the extensive NORYL portfolio into distinct categories based on their primary characteristics and target applications.
