CarCareTruth tracks Alpha-Methylstyrene-Isoamylene-Piperylene Polymer (CAS 62258-49-5) as a car-care ingredient.
No significant health hazard identified for the polymer itself. The primary health concern in rubberized undercoating products is the solvent carrier (toluene, methyl acetate), not this polymer resin. No Prop 65 listing. No acute toxicity data available per SDS.
Alpha-methylstyrene-isoamylene-piperylene polymer (CAS 62258-49-5) is a synthetic hydrocarbon resin derived from the copolymerization of alpha-methylstyrene, isoamylene (2-methyl-2-butene), and piperylene (1,3-pentadiene). In rubberized undercoating formulas, it acts as a flexibility and adhesion modifier that improves the cohesive strength and chip resistance of the cured asphalt film. It is classified as a synthetic rubber polymer/hydrocarbon resin rather than a conventional elastomer.
