In many applications, both PA6 and PA66 are suitable materials of consideration. However, there are certain situations where one is better than the other. In choosing the right nylon, the following often need to take into considerations:
Very short-term temperature spikes close to HDT or melting temperature
The heat deflection temperature of PA66 is higher than that of PA6. PA66 should be preferred when temperature is above 215℃ but below 250℃. But note this only holds for short period of heat shock or spikes application, any extended application 250℃ or above other nylons such as HTN, PA6T or PA46 should be considered;
Hydrolysis critical environments
Moisture absorption of PA66 is lower than that of PA6, and thus PA66 would be preferred for applications in hot water environment;

Polyphenylene ether (PPE)
Our modified Polyphenylene ether (PPE) resins are extremely versatile amorphous engineering thermoplastics, which together with Polystyrene (PS) can form various miscible blends with variety of characteristics. The modified PPE can be utilized in many industries whose requirement could be ranging from basic properties to specialized applications.
Key Features
High heat resistance
The various grades offer a range of different excellent short-term and long-term thermal resistance properties;Excellent dimensional stability / very low water absorption
The modified PPE resins have outstanding hydrolytic stability at both room and elevated temperatures. The low water absorption characteristic (which is amongst the lowest of any engineering thermoplastics) contributes to the retention of properties and dimensions, which is very suitable for high humidity and even steam environments. This feature allows product to meet tight injection molding tolerances and deliver molded part with high reproducibility;Low creep and outstanding retention of mechanical strength at elevated temperature
Modified PPE has outstanding retention of flexural and tensile strength at elevated temperatures. The gradual reduction in modulus allows molded parts to be used with predictable performance over a wide temperature range. Similarly, the low creep behavior at elevated temperatures is contributed by the inherent high heat resistance of the material;Non-brominated and non-chlorinated flame retardancy
PPE can be modified into having flame retardant properties that conform to UL94 standard offering the V0 rating. The non-brominated and non-chlorinated flame retardant system used makes it an excellent option for environmental friendly products;Outstanding electrical properties
The values for the dielectric strength, relative permittivity and the dissipation factor are also amongst the lowest compare to other commonly used polymers. This advantage that modified PPE exhibits makes it potentially excellent candidates for demanding electrical and electronic applications, especially under wide temperature range, high humidity and frequency variation environments.
