CarCareTruth tracks Butadiene-Styrene-meta-Divinylbenzene Polymer (CAS 26471-45-4) as a car-care ingredient.
Crosslinked polymer — not bioavailable in the same sense as monomer or small-molecule chemicals. No significant health hazard for the cured polymer itself. The butadiene and styrene monomers used to produce this polymer are classified hazardous, but residual monomer content in the finished polymer is typically very low. No Prop 65 listing for the polymer.
Butadiene-styrene-meta-divinylbenzene polymer (CAS 26471-45-4) is a crosslinked synthetic rubber derived from butadiene, styrene, and divinylbenzene. The divinylbenzene crosslinker creates a network structure that improves the mechanical strength and chemical resistance of the cured film compared to linear SBR. In rubberized undercoating formulas, this polymer is a key contributor to the rubber-like flexibility and chip-impact resistance that distinguishes rubberized coatings from simple asphalt undercoatings.
