A small change in. temperature results in large change in forming force. This technique can be used to process all thermoforming grades of. polypropylene. Melt phase forming is performed at temperatures ranging from 170ÂºC to 180ÂºC and requires polypropylene grades with a. high melt strength. Parts formed with Melt phase forming are more even, have lower residual stress and greater heat. resistance.
