what is pa66?
PA66, also known as Polyamide 66 or Nylon 66, is another type of synthetic polymer in the nylon family. It’s produced by combining two chemicals—hexamethylenediamine and adipic acid—through a process called condensation polymerization. Compared to PA6, PA66 has a slightly higher melting point and better resistance to heat and chemicals, which makes it ideal for applications needing extra toughness, like engine parts, industrial gears, and electrical connectors. It’s strong, durable, and holds up well under stress, so it’s commonly used in both engineering and consumer products. Essentially, PA66 is a sturdy, heat-resistant material suited for demanding uses.

Polyamide66 FAQs
What is the melting point of PA66?
The melting point of PA66 is around 255–265°C (491–509°F), which is higher than PA6. This makes it more suitable for high-temperature applications.
How does PA66 compare to PA6?
PA66 has better mechanical strength, higher melting temperature, and lower moisture absorption than PA6. However, it is slightly more expensive and less flexible.
Is PA66 good for injection molding?
Yes, PA66 is widely used in injection molding. It offers good flow properties and forms strong, durable parts with dimensional stability.
Does PA66 absorb moisture?
Yes, like all polyamides, PA66 is hygroscopic. But compared to PA6, it absorbs slightly less moisture, which helps maintain its mechanical performance over time.
Is PA66 flame retardant?
Standard PA66 is not inherently flame retardant, but flame-retardant grades are available for electrical and electronic applications.
Can PA66 be reinforced?
Yes. PA66 is often reinforced with glass fiber to improve stiffness, heat resistance, and dimensional stability, especially for automotive and industrial parts.
