Why Does Nylon Pa66 Material Dominate The Copper Terminal Block Market In China?

Currently, nylon PA66 is the mainstream material for copper terminal block connectors in China. This is because the use of PA66 as the insulating shell for copper distribution block connectors is becoming increasingly common in the industrial connector market. Many domestic manufacturers combine copper terminal strip connectors with PA66, directly specifying in their product descriptions that the shell material is PA66 and meets the UL94-V0 flame retardant rating. Furthermore, in terms of production volume, many manufacturers are promoting their products using the label "PA66 Copper Contact Feed - Through Terminal Block".
