Abstract : Plastic and rubber materials, has several properties and electrical Almikanekh which allowed it to many industrial applications, for example, be used in Alawazal industry and inhibitors accumulation shipments static packaging wires and cables Alkahrbaah, and also to protect against interference Alkahromagnattsah The rubber and plastic materials are good insulators, which could improve the conductivity property have to add certain materials have high self-connected property such as carbon black. Given the many uses of Mpelmaren (NBR) / EBDM) vulcanized in industrial applications has been used in this research, so prepare five sets of samples. The first group (100 NBR / 0 EBDM) different concentrations of carbon black of the type HAF (0-80 phr) the second group 75 NBR / 25 EBDM) Group III (25 NBR / 75 EBDM) Group D (50 NBR / 50 EBDM) Group fifth (0 NBR / 100 EBDM) in the same concentrations of black carbon ratios .oba samples have been prepared using the same method and steps, and then subjected to a thermal process of reconstruction at a temperature 70 C0 for 25 days. The work is divided in this letter to the two foundations first is concerned with the effect of the hybridization process on the different properties (Alkahrbaah and mechanical) and also the effect of adding different concentrations of carbon black of the type HAF on properties Alsabakh.binma interested in the second part of the message to study the correlation between each of the electrical and mechanical properties and also study the properties Almicano thermal hybrid piece of polymers. Measurements of the mechanics of the samples was observed growing plants survived values increase carbon black, where the Great value at a concentration of 80 phr of polymer matrix consisting of the ratio G2. And using the model HT model possible explanation properties carpenter samples using the approximation Cohen where Adhrt theoretical results aligned well with the results Alamlah.kma observed decrease Barmitr n which refers to the number of flexible chains between the occasional tangles up Black carbon and increase the proportion of polymer EBDM within the matrix and examine the effect of temperature on mechanical properties of the observed increase in temperature affect the impact of an active on the polymer to the wife as followed ease the movement of polymer chains leads to a decrease in all of the stress of the moment of the pieces and the stress of the moment to bow in contrast, the increasing value of the emotion of the moment of cutting up Black carbon and increasing obstacles to ease the movement of polymer chains standing, all from the moment of cutting stress and stress moment to bow. As possible activation energy account for the moment the pieces and study their value change with all of the stress the user and the concentration of carbon black and ratios hybrid in Alamblmr.opasthaddam Nelson equation is the average molecular mass between entanglements account where the observed increase MC increasing concentration of carbon black and the temperature increased Bmalomah MC values we can calculate the degree the intensity of the internal tangles where recorded decreasing concentrations of carbon black increased due to increased carbon concentrations within the matrix as entanglement density values recorded a decrease and an increase
