Elastomeric adhesives are formulated from one or more of the many synthetic rubber polymers (or natural rubber) to provide highly flexible, resilient bonds to a variety of substrates. These compounds are based on several basic polymer types and are available in a wide selection of forms for processing by a variety of assembly methods. The most popular synthetic polymer types are: Polychloroprene, styrene-butadiene rubber, nitrile rubber, and butyl rubber. Generally, elastomeric adhesives are characterized by being: Versatile, economical to use, good for quick assembly, available in many standard formulations, easily tailored to process and product requirements, of high peel strength, and thermoplastic or thermosetting.
