What are the positive sides of plastics we should look into?

Humans have benefited from the use of polymers since approximately 1600 BC when the ancient Mesoamericans first processed natural rubber into balls, figurines and bands (Hosler et al. 1999). In the intervening years, man has relied increasingly on plastics and rubber, first experimenting with natural polymers, horn, waxes, natural rubber and resins, until the nineteenth century, when […]

Calcium Carbonate CaCO3 Limestone power…

Calcium carbonate (CaCO3) is the most widely used filler in polymer formulations. As a filler, calcium carbonate allows cost reduction and improved mechanical properties. It is found in sedimentary rocks (chalk, limestone), marbles and minerals (dolomite). Some typical properties are: density 2.7-2.9 g/cm3; pH of water suspension 9; particle size 0.2-30 μm; oil absorption 13–21 g/100 […]
