Efforts to make rubber products more environmentally friendly (green) continue to increase. These efforts have become increasingly important to all rubber companies, large and small. Suppliers that produce rubber additives have increasingly focused efforts to provide products to the rubber industry that help meet the goal of increased sustainability. In this regard, Rhein Chemie (RCH), a business unit of Lanxess, currently has a sizeable portfolio of sustainable additives for rubber compounds, and also continues to explore the development of new products that meet the challenge of increased sustainability. This article will focus on currently available products and future products under development that will aid rubber companies in achieving the goal of more environmentally friendly products.

Several products that can serve more than one purpose in rubber compounds are examined, including anti-reversion agents, dithiophosphates, curing activators and blowing agents.

Mathematical models are used to better understand and quantify the effect of HNBR polymer characteristics, including degree of polarity, molecular weight and residual double bonds on the mechanical and dynamic properties of peroxide cured compounds.

Performance of a novel sustainable oil specially developed for the tire industry is studied and compared with typical oils in typical S-SBR/BR tire tread formulations
with carbon black and silica/silane. In terms of mechano-dynamic properties, a shift of the maximum tangent delta towards lower temperature is observed.
