Avient engineered a new customized formulation for the part, which provided both the processability required for extremely short cycle injection-compression molding, as well as including an additive to stabilize the material when in contact with copper. This additive protects the door from cracking as it comes into contact with copper particles over time. In addition, the new material also provides anti-static properties and low VOC levels, which helps the system adhere to regulations such as the Vehicle Interior Air Quality (VIAQ) standard.
