VOLGOGRAD (Plastkard) -- In terms of its strategic development, Plastkard has invented a new recipe format of vinyl chloride polymerization process and samples of high-molecular PVC-S with K=80. The absorption mass of PVC plasticizer with K=80 forms at least 30g for 100g of PVC; thermostability at 160╟С is at least 30 minutes. This polymer has very low quantity of defects like ⌠fish eye, and has quite narrow allocation of PVC particles. The new polymer can be converted in compositions with plasticizer and without it.
PVC with K=80 has undergone preliminary testing at Nikochim Group's plants. Test results have shown potential of the new PVC grade as regards production and technical purposes. Finished goods made of it should have high physical and mechanical properties and good stability at different temperatures (from -60╟С to +180╟С). Research has given grounds to organize production of the new PVC grade.
