Polyamide (PA6 and PA66)
Polyamide are also commonly known as Nylon, the most common types of polyamides are PA6 and PA66, which are characterized by balanced mechanical, electrical and tribological properties; they are often material of choice when it comes to applications that require high strength, rigidity and flame retardant ability.
Key Features
- Good balance of mechanical properties;
- Good electrical insulation properties;
- Good chemical and oil resistance;
- Good creep resistance;
- Anti abrasion and sliding friction properties;
- Generic resin is UL94 V2 rated;
- Good thermal resistance;
- Easy to process and mold.
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:
Continuous high temperatures, up to 185℃
PA6 have better long term heat ageing performance than PA66 and should be material of choice for application require running for extended period of time;
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;
Very low temperatures
Generic PA6 is more ductile than PA66 at low temperature, but both types of polyamide could be modified through other means for low temperature applications.
Applications
Impact modified grades
Case / housing for power tools, recreation equipments;
Glass Fiber reinforced grades
Control unit, gear, fittings, bearings, automotive underhood, industrial fans or blades, bobbin, furniture parts;
Flame Retardant grades
Switch gear. sensor, connector, circuit breaker;
Mineral modified grades
Furniture parts, switch components, parts that require rigid and good surface.
