Abstract:
Polyvinyl Chloride (PVC) is one of the most widely used plastic materials globally, owing to its versatility and cost-effectiveness. However, its inherent thermal instability and rigidity necessitate the incorporation of various additives to enhance its processability and final product properties. This paper investigates the influence of common additives-specifically calcium carbonate (as a filler), tin carboxylate (as a stabilizer), and impact modifiers-on the mechanical and physical characteristics of rigid PVC compounds, particularly those used in pipe manufacturing. The study is based on the formulation and testing of three distinct PVC blends (A, B, and C) with varying proportions of calcium carbonate and stabilizers. The methodology focuses on compounding and impact testing, aiming to determine the optimal formulation for improved performance and reduced raw material cost. The findings are expected to contribute to the development of more durable and cost-efficient PVC pipe formulations.
