Establishments primarily engaged in manufacturing synthetic rubber by polymerization or copolymerization. An elastomer for the purpose of this classification is a rubber-like material capable of vulcanization, such as copolymers of butadiene and styrene, or butadiene and acrylonitrile, polybutadienes, chloroprene rubbers, and isobutylene-isoprene copolymers. …
Examples: Acrylate type rubbers, Acrylate-butadiene rubbers, Acrylic rubbers, Butadiene rubbers, Butadiene-acrylonitrile
