Study of rheological behavior and other physical property matrix by reinforcement of calcium carbonate in different ratio in High density polyethylene

ABSTRACT Rheology is a science that deals with deformation of material as result of an applied stress . It is also defined as the study of flow deformation behavior of polymers or in other words “study of flow pattern or characteristics of the polymer Rheological properties provide an insight into the processability of the material, polymer architecture , morphology , chain branching in polymer. Specific gravity values represent the main advantage of plastic over other material , namely , light weight . All plastics are sold today on a cost per pound basis and not on a cost per unit volume basis Durometer Hardness test is based on penetration of a specified indenter onto the surface of the object. Indentation hardness is inversely related to the depth of penetration , elastic modulus as well as viscoelastic behavior of material In present experiment Particular size of calcium carbonate is reinforced in high density polyethylene (HDPE) in different weight ratio .The objective of present experiment to study the Rheological property via Melt flow index, density and Hardness of reinforced blended material as compare to neat material.
