Compared to Nylon 6/6, cast Nylon 6 has improved processability, creep resistance and surface appearance. It can be molded about 80°F lower with less mold shrinkage because it is slightly less crystalline. However, it absorbs moisture more rapidly and has a lower melting point. Nylon 6 is also available in natural (straw colored) and black. Natural unmodified Nylon 6 (MC®907) is FDA, USDA and 3A-Dairy compliant.
