Abstract

Anurag Singh and Atul Kumar Seth

The current research about Polyvinylchloride (PVC) was compounded with some additives to improve physical and mechanical properties. PVC (K value ranging 70) was used as the base polymer. Plasticizers, fillers, stabilizers, pigments, and lubricants were mixed in standard concentration units of parts per hundred resins (phr)" with the base polymer. Cable compound and shoe compound were made in the plasticized-PVC category with primarily plasticizing additives such as dioctyl phthalate (DOP), Calcium carbonate, Stearic acid, Calcium zinc stearate. At present work is aimed to compounding of PVC with various additives and studied its various properties. The mechanical properties of the compounded samples, such as tensile strength, elongation at break, hardness, and specific gravity, were inves- tigated experimentally. Tensile strength increased significantly from 16.62 Mpa and elongation at break 300% (The hardness (shore A) of all compounds was obtained 93. The volume resistivity was found to be 4x1014 Plasticizers had a direct proportional impact on elongation at break but an inverse proportional impact on tensile strength. The study provides the application of PVC compound incorporated with various additives affect its physical and mechanical properties for development of various application in electrical cable and house wiring.
