PA 66
Brand: 
- Mechanical strength
- Resistance to wear
- Resistance to heat
- Creep resistance
Interested in this product?
This material offers enhanced mechanical strength, resistance to wear and heat, and stiffness to PA6.
Its creep resistance too is better, whereas its impact strength and mechanical dampening capabilities are slightly less efficient.
This material is suitable for mechanical machining in automatic lathes.
