Description Buna® SE 1793 is a butadiene-styrene copolymer, produced by cold emulsion polimerization, using fatty and rosin soaps as emulsifiers. The elastomer is extended in oil with a PCA (Polycyclic Aromatic Hydrocarbons) content less than 3,0% and PAHs (Individual Polycyclic Aromatic Hydrocarbons) content less than 10 ppm which is compliant with the European directive 2005/69/EC. The monomers are randomly distributed in the polymer structure, while the butadiene fraction is found in its major part in the trans configuration with small fractions of cis and vinyl configurations. CAS No.: 9003-55-8. The rubber is protected by a staining stabiliser system. Typical Values Mooney (1+4 @100°C) : 51Styrene : 23,5 %37,5 phr TRAE-Oil Application Buna® SE 1793 is used where there is a need for resistance to wear and tear, resistance to cracking and excellent processing conditions. It processes easily in extrusion and calendering, due to its oil content. It is used in tires, retread, conveyor belts, piping, hoses, tubings, carpets, moulded products in general and shoe soles.
