PA6 milky white or light yellow transparent to opaque cutin crystalline polymer, free coloring, good toughness, wear resistance, self-lubrication and less rigid, good low temperature resistance, resistance to bacteria, can slow burning, from slow extinguish fire, dripping, foaming phenomenon, forming excellent processability, plastic injection molding, blow molding, casting, coating, powder molding, machining, welding, adhesive. PA6 is the highest water absorption of PA, poor dimensional stability, and affect the electrical performance (breakdown voltage).
