Dow SE BR-1202D Stereospecific high cis-1,4 Polybutadiene (BR)
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	SE BR-1202D is manufactured by a solution process using cobalt catalyst which produces polymers with a very light color and low level of impurities. A non-staining stabilizer is added during the production process. It complies with the compositional requirements of the food packaging regulations of European countries and the USA. BR-1202D is uses for the manufacture of toughened polystyrene employing grafting processes. BR-1202D is supplied in bales weighing ca. 34 kg. Bales are wrapped in 60 micron PS film.
