Calcium Carbonate is the most important mineral in producing PVC foam and is used in high concentrations for products such as graphics cards, profiles, and foam core tubes. At high filler contents, it is important to choose the right Calcium Carbonate to maintain the required balance between stiffness, lightweight, and impact resistance. Omya has worked with the industry from the beginning and is continuously developing new products and ideas to further increase filler content and improve profitability. If you would like to learn about the latest developments to produce a PVC foam that is even lighter than the foams commonly available on the market, get in touch with Omya.
