Calcium Carbonate: Low Cost, Big Impact


At Washington Penn Plastic, we custom formulate materials to meet your specific property requirements.  Calcium carbonate is a commonly used filler because of its low cost and beneficial properties.  Calcium carbonate-filled polypropylene products offer an excellent balance of stiffness and impact. In addition, it provides superior color consistency, creating a better appearance for any application. Based on that, calcium carbonate is widely used in applications where durability and appearance are necessary, such as lawn furniture, tractor parts, small appliances and shutters.
