The effect is pronounced: for some grades of polypropylene, cooling from 20°C to –20°C increases stresses by an amount corresponding to a million-fold decrease in contact time during the impact. This is where cryogenic grinding comes in. To allow time for the material’s temperature to fall sufficiently, the liquid nitrogen is sprayed onto the feed in a special
