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.

Norst

NorthStar Elastomers, LLC, manufactures and markets several forms of Tirecycle™, for different purposes and markets. Treatment K is an activating adhesive polymer, while T 608 for tires and MBS 800 for hoses are basic Tirecycle™ masterbatch compounds. All can be tested and adjusted for your specific master batch manufacturing and performance needs. The fundamental product is “a pre-cured, engineered, particulate elastomer with a 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 masterbatch 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.

Tirecycle

Norst® PB-800 is Particulate for thermoplastic applications. It is odorless and highly stable.

Norst® PB-800

Tirecycle® T 608 is an advanced material based on rubber crumb. It is added to SBR, NR, EPDM or other rubber compounds to enhance both their performance and our environment. The basic formulation uses #34 to infinity mesh crumb. We can formulate it with 60/80 mesh crumb, 15/20 mesh, or other mesh sizes.

Tirecycle® T 608

Norst® PB-402-24 is a highly modified polyisobutylene polymer that exhibits high tack and cold flow over a very wide temperature range (-70°F to 450°F, with variants stable to 650°F and 800°F). It is impermeable to water or oxygen. It has good tensile and bond strength, high film strength, permanent tackiness, excellent aging/weather resistance, low stain, low electrical conductivity. It is odorless, colorless, and highly stable. Chemical resistance is comparable to other polyisobutylene polymers. PB-402-24 can be used as a high performance additive in any non-aqueous system where high tack and elasticity are needed.
