Mineral fillers offer cost reduction – and sometimes enhanced properties – to polymer formulations. Siddhartha Roy outlines ground calcium carbonate’s changing role in the growing polymer market
It is estimated that about 5% of the Earth’s crust is
some form of calcium carbonate, either as calcite, limestone,
chalk, marble or aragonite or through impure forms like
dolomite. While some minor portion of naturally occurring
calcium carbonates have formed due to geological processes, the
majority has its origins...
