Buna SE 1502 L is a butadiene-styrene copolymer, produced by cold emulsion polimerization, using fatty and rosin soaps as emulsifiers. 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 non-staining stabilizer.
