Summary

Basing on the results of physical and plastographic studies,the effect of binary lubricating systems (stearin-calcium stearate and wax A – calciumstearate) on the processing properties of rigid PVC compositions has beendetermined. It has been found that the cooperations of lubricating agentsdepends on the type of heat stabilizer used. In he systems composed of stearinor wax A with calcium stearate a synergic effect has been observed, inparticular in the presence of an organotin stabilizer.
