EFFECT OF THE FILLER FOR A STABILIZATION STABILITY POLYETHYLENE COMPOSITION
The main purpose of the given work is the study of stability polymeric composite materials to influence of the raised temperature in presence of oxygen of the air. The particular stress in the work is put on the study of change deformation-strength properties of filled polyethylene's compositions during the long impact of high temperature. In this work were used dispersible fillers of inorganic nature - chalk Omyacarb 2-UR and talc Fintalc 2-UR, which have a good compatibility with polymers. As a result of negative action of the raised temperature thermal-oxidative degradation and (or) structuring take place in polymer. Change the molecular structure brings about changes to performance attributes of the polymeric material: gets lost resilience, increases harshness and fragility, falls mechanical toughness, changes the color, smooth surface becomes rough. For deceleration of the destructive processes on the stage of preparation was entered substance, promoting of preservation the initial properties of compositions - Irganox 1010. The article shows the effectiveness of the action Irganox 1010 in compositions with different fillers.
