TECAMID® 66 HI natural

PA 66 with reduced thermal degradation

TECAMID 66 HI features a PA 66 with a special additive that reduces the thermal degradation of the molecular chains. As a result, service temperatures of around 59°F higher can be achieved compared to the capabilities of standard PA66 types.
