TECAMID 6/3 TR natural

PA 6/3 TR natural

Due to its chemical structure, TECAMID 6/3 TR natural is one of the amorphous polyamides, and is consequently transparent to a high degree. The amorphous structure also brings about slight shrinkage and tendency to warp, but also delivers a high amount of toughness. In addition, PA 6/3 feedstocks demonstrate high chemical and stress crack resistance. Thermal and dimensional stability, along with good mechanical strength rounds out the unique property profile of this transparent polyamide 6/3.
