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.

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.
Adhesives have been described as the diplomats of the rubber world, bringing materials together. Adhesion promoters help facilitate this process. To extend this metaphor, if adhesives are the diplomats, tackifier resins are the handshake that binds the agreement within rubber. These additives are generally medium molecular weight chemicals that are added to rubber compounds, altering their properties by imparting improved tack.

The United States has almost 1 million oil producing wells, and most require the use of an artificial lift system. There are various methods of artificial lift which are utilized to increase pressure within the reservoir to push oil to the surface. This allows operators to enhance production and extend well life.
