Abstract

Ultrafine natural calcium carbonates, with a mean statistical dia. of 0.5-0.7 mu m and a max. cross section of 3-4 mu m prepd by grinding chalk or calcite are used as fillers in rubber, neoprene foams, hard neoprene and neoprene coatings. Compared to ordinary natural calcium carbonate fillers (mean dia. 3-4 mu m, max. dia. 10-20 mu m). The ultrafine fillers result in an improvement in the mechanical properties of vulcanised rubber, improve the dispersion of reinforcing silicas in natural rubber, allow a reduced wt. ofocarbon black in neoprene formulations, and improves the cellular structure and mechanical properties of neoprene foams. In hard neoprene formulation the ultrafine calcium carbonates compare well with pptd calcium carbonates on terms of surface and mechanical properties and resistance to ageing while in neoprene coatings their use results in improved whiteness, an economy of pigment and the opportunity to work with layers 20-25 mu m thick.
