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.
NorthStar Elastomers, LLC (NSE), is proud to be a GREEN company with Solvent Free / Sustainable production. NSE promotes “Mechanochemistry”. In our standard products, no solvents are used. In addition, NSE’s production creates no processing waste or residue, and does not pollute or cause environmental hazards. We can effectively and efficiently use off-spec and recycled materials and tailor products to manufacturer end use. Our products have been in use across the world for more than 25 years.
Garden Hose – Want a tougher hose, long life, cost effective, beat out Asian imports? Use a MBS 800 mix with your NR, Butyl or EPDM masterbatch.
Adhesive Welds – Want a strong, long life, non-drying adhesive strip, to grab those edges and be there when you make the welds?Add Norst® PB 500 to your EPDM masterbatch.
Permanent Performance–a hallmark of NORST® polyisobutylene polymer and PIB-alloy base
NORST® PB-402 and PB-403 are PiB-graft-PIB viscous fluids for use in cable fill, sealants and polyolefin PSA’s and for boosting performance in low-styrenic block copolymers and low VAC ethylene copolymers. NORST base polymers are non-drying, non-migrating with very high gas barrier performance; cold flex down to -50 C; and cold temperature tack strength. They can be used as part substitutes for non-polar tackifier resins. These PIB alloys have polydispersity (Mw/Mn) above 30 and are unique in the industry with unmatched tack strength and high temperature resistance.
NORST® PIB-graft-Ethylene/Propylene High temperature – High elastic bond performance
PB-400 | PB-500 | PB-600 | PB-800 | PB-1620
The PB-series is listed in increasing high temperature adhesive shear strength. Any of these can be blended for tailored, tack, peel and shear. Preferred tackifier resins are C5 hydrocarbons. NORST base polymers exhibit superior bonding to low surface energy substrates.
