Dow receives R&D award for Index Interpolymers; product development plant located in Sarnia, Ontario

In recognition of the development of ethylene styrene interpolymers, soon to be known commercially as INDEX* Interpolymers, Dow was named as a winner of R&D Magazine’s 38 th annual R&D 100 Awards.

INDEX Interpolymers will be a new and novel family of then-noplastic polymers based on copolymerizing ethylene and styrene, and potentially other monomers, produced via INSITE* Technology, Dow’s proprietary, single-site, constrained geometry catalyst technology. Dow’s product development plant for INDEX Interpolymers is located in Sarnia, Ontario.

11 polymer scientists have been trying to successfully copolymerize ethylene and styrene, in reactor, for a long time. Finally, with INSITE Technology, Dow has found the catalyst to make this happen,” says Jill Allemang, global business director for ethylene styrene interpolymers. “The R&D 100 Award is a great honor and we hope, that through successfully bringing the technology to our customers, Dow can demonstrate how new milestones can be achieved in the evolution of plastics.”

Regarded by The Chicago Tribune as “the Oscars of Invention,” the R&D 100 Awards are presented to the 100 most significant technological inventions of the year.

INDEX Interpolymers will exhibit unique properties not observed in either polyethylene or polystyrene homopolymers. The material offers the toughness and solvent resistance of polyethylene, along with the stiffness, formability, and appearance of polystyrene resins, which are recognized for their high gloss and processability.

Dow started up the 50 million-pound-per-year (22,700 metric tons) product development plant for ethylene styrene interpolymers in Sarnia in the fall of 1999. The plant will provide the capacity needed to seed the many markets in which INDEX Interpolymers will find uses including: coated fabrics, foams, footwear, toys, flooring, asphalt modification and wire and cable.

A full-scale, 250 million-pound-per-year (113,500 metric tons) commercial plant is being engineered to be located in Sarnia to come on stream during the next couple of years, pending approval from Dow’s Board of Directors.
