Vydyne 21X1 is a general-purpose, unfilled, PA66 resin. Designed principally for injection-molding applications with the added benefit of improved flow during the molding process. 21X1 offers the same well-balanced combination of engineering properties characterized by high strength; rigidity; good toughness; high melt point; good surface lubricity; abrasion resistance and resistance to many chemicals, machine and motor oils, solvents and gasoline.
