TECAST® T black

pa 6 c

This is a black colored cast nylon type 6 that exhibits more UV resistance than TECAST® T Natural, and is therefore much better suited for outdoor applications than our other standard grade formulations. The polyamide type 6 material has good wear and abrasion resistance and offers a good mix of mechanical properties.
