DuraForm PA model

DuraForm PA model

DuraForm PA model

DuraForm PA

DuraForm PA is based on nylon 12 and provides excellent mechanical properties for parts used in functional testing. In many cases low volumes of end-use parts can be manufactured offering long term stability with good chemical resistance and low moisture absorption. Parts can also be sterilised using autoclaving and comply to USP Class VI testing. DuraForm PA is easily processed delivering consistently good surface resolution and feature detail. The choice material where functionality is the key requirement.
