Vitamide PA6 – PA66 - For technical data Click here

Polyamide 6 (PA6) and Polyamide 6.6 (PA6.6) are widely used due to their very good performance / cost ratios. PA6 has a slightly lower temperature resistance (HDT) versus PA6.6 and has a lower melting temperature. It has worse hydrolytic stability but better long term ageing. It has better impact resistance at room temperature. PA66 is used when PA6 reaches its limit temperature or when the hydrolytic stability of PA6 is not sufficient anymore. PA66 is generally more expensive and the end use must be considered carefully when selection between PA6 and PA66. All nylons provide good surface appearance and good weld strength. In the E&E applications where specific tests (GWIT, UL94) need to be passed, Polyamides 6 and 66 can be flame retarded. Halogenated and non Halogenated FR solutions are available. A wide range of grades are available offering enhanced impact strength, UV and heat stability, fibre, mineral reinforcement and multiple combinations of the above specific to the application requirements.
