TECAMID 66 HI brown

PA 66 with reduced thermal degradation

TECAMID 66 HI brown features a PA 66 with a special additive that reduces the thermal degradation of the molecular chains. As a result, service temperatures of around 15°C higher can be achieved compared to the capabilities of standard PA66 types.
