Abstract
Soft PVC foam materials are produced by feeding the ingredients under a pressure 5 atm. into a self-cleaning, high speed, centre cylinder rotation mixer; applying the heat necessary for gelling and foaming; and allowing the product on extrusion, as required, to expand and cool. The rotor and the stator of the high speed mixer have on their surfaces a pattern of bosses, ribs or similar, and the highest projections of each form a uniform annular slot, the width of which corresponds at most to the height of the bosses or ribs. Enables the correct amount of heat to be applied uniformly without any overheating.
