Poly-propylene carbonate
WebPoly (propylene carbonate) (PPC) is an aliphatic polycarbonate which is mainly used as a packing material and binder resin. The ester group allows the backbone to have molecular flexibility. It is prepared by reacting carbon dioxide and propylene oxide. It has a low thermal stability which can be improved by capping the polymer with active agents. WebCalcium carbonate and talc are successfully used in PP to increase properties and dimensional stability. The short-term and long-term high-use temperatures are 130C and 90C. These temperatures are ...
