Certainly! Nylon 66 (PA-66) is a type of polyamide plastic obtained by polymerizing hexamethylenediamine and adipic acid. Here are some key properties of PA-66:
Strength and Durability: Nylon 66 is known for its strength, durability, and resistance to wear and tear
Stiffness and Toughness: Compared to PA6 (another type of nylon), PA66 is stiffer and tougher but more brittle. It’s advisable to use PA66 when higher stiffness is required at the expense of resilience.
Machinability: PA66 can be easily machined, making it suitable for various engineering applications.
Thermal Properties:
- Melting temperature: Approximately 255°C.
- The coefficient of linear thermal expansion is around 95 x 10^-6 (between 23°C and 60°C).
- Maximum allowable service temperature in air: Continuously up to 165°C, short periods up to 180°C.
- Minimum service temperature: -30°C.
Electrical Properties:
- Dielectric constant: 7.
- Dielectric strength: 25 KV/mm.
- Volume resistivity: 10^12 Ωcm.
- Dissipation factor (tan ∆) at 1 MHz: 0.06.
Other Characteristics:
- Water absorption at saturation: Approximately 2.6%.
- Ball indentation hardness: 150 N/mm^2.
- Shore hardness D: 89.
- Oxygen index (flammability): V2 according to UL 94.
Remember that these properties are indicative and can vary based on specific formulations and processing methods. I recommend referring to the manufacturer’s data sheets if you need more detailed technical information. Is there anything else you’d like to know about nylon 66? 😊
