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.

General Purpose and Automotive Grades (PX and N Series)

This category includes many of the workhorse grades, often unfilled and well-suited for automotive interior and exterior components.
