TECHNYL® A 221 Natural FA is an unfilled polyamide 66, for injection moulding, with a special crystallizing agent, for fast cycles. This grade 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 moulded parts. It is designed to be used in food contact applications.
