STUDY SOME PHYICAL AND MECHANICAL PROPERTIES OF RUBBER BY UISING CONDUCTIVE CARBON BLACK

Abstract

Aim of this Reasch to Study Some Physical and Mechanical Properties of rubber such as( the Electrical conductivity ,hardness,tensile strength at break,Modulus of elasticity at elon.300%,Elon.at break,Torque,Scorch time(Ts2)) for taypes of rubber for example natural rubber (NR) and industrial rubber (butadiene-BR) by using conductive carbon black with addition Loading level (10,20,30,40,50 pphr) from conductive carbon type( N375) . also using fixed quantities from (CaCO3) and metals oxides e.g ( Fe2O3) and ( ZnO) are not effecting on mechanical properties for final product where giving the experimental results that improvement of electrical conductivity and mechanical properties for Natural rubber(NR) more than of thes properties in industrial rubber(butadiene- BR) as same as for loading level of conductive carbon
