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
Typical applications of Noryl® PPX Resins electric motors, under bonnet, metal replacement, structural foam mouldings
Good Balance of Properties of Noryl® PPX
Noryl® PPX balances high heat resistance, excellent dimensional stability, and outstanding dielectric strength. Noryl® PPX automotive-specific grades and high modulus grades can be used in place of stamped steel and die cast metal in tight tolerance, functional assemblies
Noryl® PPX offers excellent melt strength and processibility
The wide thermoforming and injection processing windows of Noryl® PPX - foam grade is capable of high heat, exhibiting creep resistance and excellent modulus.
The harmony of Noryl® PPX with TPO materials
Noryl® PPX offers good foam adhesion and compatibility with thermoplastic elastomers.
Stiffness and Strength properties of Noryl® PPX
Noryl® PPX has a 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.
Chemical Resistance of Noryl® PPX
Noryl® PPX is virtually unaffected by many detergents, acids and bases
Noryl® PPX is regrindable
Noryl® PPX is regrindable for re-use or incorporation in olefinic blends
Impact Strength of Noryl® PPX
Excellent impact strength, Noryl® PPX is virtually unaffected by humidity and only slightly affected by temperature
Hydrolytic Stability of Noryl® PPX
Superb hydrolytic stability – Noryl® PPX has the lowest water absorption rate is of any engineering thermoplastic
