Domo TECHNYL® A 221 PA66, DRY
Categories:	Polymer; Thermoplastic; Nylon (Polyamide PA); Nylon 66 (PA66)
Material Notes:	Description TECHNYL ® A 221 is an unreinforced polyamide 66, medium viscosity, for injection molding, with a special crystallizing agent, for fast cycles. It is available in natural colors. Benefits: The product offers a good combination between primary properties of the unreinforced polyamide 66 and processing properties leading to increased productivity. These performances are associated with excellent dimensional stability and good rigidity of molded parts. Available in: Asia Pacific, Europe, Latin America and North America Regulations compliance: Grades produced or imported in Europe comply with directive 453/2010/EC, which amends REACH directive 1907/2006/EC. This grade complies with RoHS directive 2002/95/EC. Unless specified, this grade is not suitable for food contact, medical devices or toy applications. Applications: Connectors, lighters, aerosol valves… DOMO Chemicals has acquired Solvay’s Performance Polyamides Business in Europe.
