3M Bumpon SJ5300 Series Self-Adhesive Bumpers are pressure sensitive adhesive-backed polyurethane products that can be used as feet, stops, spacers and protectors in many applications. The urethane is a durable, resilient elastomer. The aggressive, high tack pressure sensitive adhesive is protected with a release liner making application fast and easy. The plasticizer-free urethane composition of the bumpons exhibit excellent skid resistance, long aging resiliency (will not crack or harden), abrasion resistance and resistance to marring and staining. Use 3M Bumpons almost anywhere slamming, scratching, nicking, scuffing, marring, sliding, vibration, or noise could be a problem for your product.
