Chardon, Ohio – Rhein Chemie Corporation’s environmentally friendly alternatives to petroleum-based products are receiving national attention. “Additives for Optimizing Renewable Resources in the Production of Polyurethane Systems & Plastics”, has been accepted for presentation at the 11th Annual Green Chemistry & Engineering Conference that will be held in Washington, D.C. from June 26-29. The technology is also a candidate for the Presidential Green Chemistry Award.

Chemists in Rhein Chemie’s Engineering Plastics Division, in partnership with Bio-Based Technologies LLC, Rogers, Arkansas, developed the additive technology to replace petroleum-based polyols with bio-based polyols, particularly in soy-based systems. The presentation will discuss some of the chemical additives that fostered the innovation and commercialization of soy-based polyols in the rigid polyurethane spray foam insulation, and retrofitted and new construction markets. Two commercial additives in particular, Addocat™ 102 and Stabaxol® P200, have provided reactivity and shelf-life stability improvements in the soy polyol side of the polyurethane rigid foam reaction.

The Green Chemistry & Engineering Conference recognizes companies for their efforts to reaffirm and extend the importance of green chemistry as a means to prevent pollution and achieve sustainability. The Presidential Green Chemistry Challenge Awards Program is an opportunity for individuals, groups, and organizations to compete for annual awards in recognition of innovations in cleaner, cheaper, smarter chemistry.
