Custom Mixing and Blending Services

NorthStar Elastomers offers optimized (over nearly 4 decades) custom mixing and blending technologies to create additives, bases and finished polymer specialties, adhesives and rubbers. Our strengths include highly viscous (to 500,000 cps @3250 F – we can discuss higher viscosity projects), self-adhesive, wide temperature range, water resistant hot melts, sealants and coatings as well as high performance rubbers.

Demonstrated capabilities include toll production for major global manufacturers seeking our unique, powerful, specialized, high energy equipment for mixing, masticating, dispersing, dissolving and blending very high viscosity materials.
