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. Generally Butyl or PIB based, compatible with NR, SBR, EPDM, PPE, most rubbers and plastics. Avoid aromatics, silicones, water-based mixtures.

Tirecycle™ Rubbers

Technically Integrated Recycle

The fundamental product is “a pre-cured, engineered, particulate elastomer with a masterbatch coherent, homogeneous, reactive surface; ready to bond into any appropriate virgin rubber or masterbatch.” Tirecycle™ is an advanced material, which upcycles and rejuvenates rubber crumb, to perform as virgin replacement or equivalent. Made predominantly from tires, but EPDM, neoprene and many other rubbers and plastics will also work. Many production wastes and used materials may be repeatedly recycled via the Tirecycle™ process, and still maintain performance.
