Description

Buna® SE 1723 is a styrene-butadiene copolymer with a bound styrene content of 23.5%, produced by cold emulsion polymerization (10°C maximum) using a mix of rosin and fatty acid soaps as emulsifier, extended in TDAE (Treated Distillate Aromatic Extract) oil with a PCA (Polycyclic Aromatic Compounds) 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 stabilizer system.

Styrene : 23,5 %

37,5 phr TDAE-Oil

Application

Buna® SE 1723 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.
