Arlanxeo SBR Buna SE 1793

Bu ürün hakkında

Buna SE 1793 is a butadiene-styrene copolymer produced by cold emulsion polymerisation, using fatty and rosin soaps as emulsifiers. The elastomer is extended in oil with a PCA (Polycyclic Aromatic Hydrocarbons) content less than 3% and PAHs (Individual Polycyclic Aromatic Hydrocarbons) content less than 10ppm 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.

The rubber is protected by a staining stabilser system.

Mooney = 51
Oil content = 27.2% by wt
