Question and Answer
NORYL PPO is an amorphous blend of (polyphenylene ether) and polystyrene. They combine the inherent advantages of PPO resins (affordable high heat resistance, good electrical properties, excellent hydrolytic stability and ability to use halogen-free FR packaging) with excellent dimensional stability, good processability and low proportion. NORYL resins offer a good balance of mechanical and chemical properties and can be used in a wide variety of applications
| Stable performance: | Heat resistance, good hydrolytic stability, high dielectric strength and optional non-halogen flame retardant in low specific gravity material. Can be designed to replace stamped steel, die cast metal, copper in functional components. Compatible with a variety of packing technologies to further tailor required performance |
| Stiffness and Strength: | High stiffness and tensile and flexural strength, even at elevated temperatures, with only a gradual decrease in modulus with increasing temperature, a key point |
| Creep resistance: | Good creep resistance, even at high temperatures, due to the inherently high heat resistance of this material, made even better with the addition of various filler systems |
| Impact strength: | Predictable impact strength remains virtually unaffected by humidity |
| Good electrical properties: | High dielectric strength and excellent electrical properties |
| Good fire resistance: | Available in non-halogenated flame retardant grades, helping products comply with a wide range of environmental standards, including UL94V-0. In addition to low toxicity per GEI 02.37.2, grades were selected to meet Department of Transportation low smoke requirements |
| Chemical Resistance: | Acids, alkalis, and many cleaners are generally good. |
| Hydrolytic Stability: | Excellent hydrolytic stability, with the lowest water absorption of any engineering thermoplastic |
| Low mold shrinkage: | Good dimensional control, and ultra-low molding shrinkage factor |
