Norst® Polymers

NorthStar Elastomers, LLC, manufactures custom blended base rubber compounds and additives, used in the manufacture of adhesives and sealants for a wide range of usage and benefits. These rubber compounds and additives are generally Butyl or PIB based, compatible with NR, SBR, EPDM, PPE, most rubbers, plastics, and asphalt. Aliphatic and napthenic solvents work very well, and we avoid aromatics, polar solvents, silicones and water-based mixtures. See Properties Chart for more Polymer product information.

Industries served: Aerospace, Automotive, Industrial, Construction, Military, Utilities


Commercial Uses
