DOI: dx.doi.org/10.14314/polimery.1983.402

Summary

Samples of domestic natural chalks have been investigated from the point of the use as fillers in cable-sheathing plasticized PVC compositions, so-called Polwinits. In virtue of the studies on chalks, plasticized compositions with chalks added and extruded cable sheathing, specifications for the chalks have been put forward. The suitability of chalk manufactured by the Diatomaccous Earth Mines at Piotrowice from a deposit of limestone in vicinity of Kielce

has been demonstrated.
