タイトルまたは説明

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. 


PERFORMANCE PROPERTIES:

1.GOOD BALANCE OF PROPERTIES
Tailorable heat resistance, good hydrolytic stability, high dielectric strength and optional non halogenated flame retardants in a low specific gravity material. May be designed to replace stamped steel, die cast metal, and brass in functional assemblies. Compatible with multiple filler technologies to further tailor desired properties.

2.STIFFNESS AND STRENGTH
High stiffness and tensile & flexural strength, even at elevated temperatures, with only gradual reduction in modulus as temperature is increased, a key advantage

3.CREEP
Good creep resistance, even at elevated temperatures, thanks to the materials inherent high heat resistance, made even better with the addition of various filler systems

4.IMPACT STRENGTH
Predictable impact strength that remains virtually unaffected by humidity

5.GOOD ELECTRICAL PERFORMANCE
High dielectric strength with excellent electrical properties

6.GOOD FIRE RETARDANCY
Available in non-halogen based fire-retardant grades, helping products comply with a broad range of environmental standards, including UL*4 V*0. In addition to low toxicity in accordance with GEI *2.*7.2, select grades have been designed to meet low smoke requirements in transportation segments

7.CHEMICAL RESISTANCE
Generally good resistance to acids, bases and many cleaning agents.

8.HYDROLYTIC STABILITY
Excellent hydrolytic stability, with water absorption rates among the lowest of any engineering thermoplastic

9.LOW MOLD SHRINKAGE
Excellent dimensional control with exceptionally low mold shrinkage factors
