Polyamide 6/6 - Nylon 6/6 - PA 6/6 Super-Tough; Fire Retardant

May 16 2001

Polymer Type

Thermoplastic

Advantages

Excellent combination of impact, flame and fire resistance when compared with unmodified polyamide 6/6.

Disadvantages

High melt viscosity due to presence of rubber particles, therefore processing problems are possible. Reduced flexural modulus and maximum operating temperature compared with unmodified polyamide 6/6.
