Polyamide 6/6 - Nylon 6/6 - PA 6/6 30% Carbon Fibre Reinforced

Polymer Type

Thermoplastic

Advantages

Extremely low coefficient of thermal expansion, good wear properties, excellent stiffness and strength, high thermal conductivity, high electrical conductivity (could also be a disadvantage depending upon application) and extremely low creep when compared with unmodified polyamide 6/6.

Disadvantages

Properties can be highly anisotropic dependant on processing conditions. Expensive compared to glass reinforced grades. Not as tough as glass grades. Natural colour of carbon-reinforced grades is black.
