The NORYL PPX alloy of polyphenylene ether (PPE) and polypropylene (PP) is an engineering thermoplastic olefin that combines the flowability and chemical resistance of PP with PPE's high-temperature performance, surface hardness and rigidity. Grades of NORYL PPX resin exhibit 30 to 50% higher modulus than thermoplastic polyolefin (TPO). Filled NORYL PPX resin grades offer high elongation, high stiffness and long-term heat resistance
GOOD BALANCE OF PROPERTIES
Balances high heat resistance, excellent dimensional stability, and outstanding dielectric strength. Automotive-specific grades and high modulus grades can be used in place of stamped steel and die cast metal in tight tolerance, functional assemblies
EXCELLENT MELT STRENGTH AND PROCESSIBILITY
Wide thermoforming and injection processing windows - foam grade is capable of high heat, exhibiting creep resistance and excellent modulus.
HARMONY WITH TPO MATERIALS
Good foam adhesion and compatibility with thermoplastic elastomers.
STIFFNESS AND STRENGTH
Wide range of stiffness, tensile and flexural strength, at both low and elevated temperatures, with only a gradual reduction in modulus as temperature is increased, a key advantage.
Virtually unaffected by many detergents, acids and bases
Regrindable for re-use or incorporation in olefinic blends
Excellent impact strength, virtually unaffected by humidity and only slightly affected by temperature
Superb hydrolytic stability - water absorption rate is among the lowest of any engineering thermoplastic
