Sustainable additives for the rubber industry
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.

Towards the modern automotive industry: Adhesive innovations with styrenic TPEs
Adhesive innovations with styrenic thermoplastic elastomers In automobile manufacturing, hot melt adhesives have numerous purposes, such as applications in the trunk, roof linings, seat assembly, filter manufacturing, emblems, trim and assembly bonding. The trunks
of modern cars, especially trucks with large storage space, are complex. Individual elements, such as the trunk floor, rear seat backs, rear covers, etc., have been produced for several years with dispersion based adhesive systems, with a growing trend of polyurethane reactive (PUR) systems.
Influence of functionalized terpolymer resin on carbon black reinforced rubber compounds
Influence of functionalized terpolymer resin on carbon black reinforced rubber compounds and corelation with tire performance In recent years, the European Union (EU) has mandated reducing greenhouse gas emissions, especially carbon dioxide (CO2). Passenger cars are responsible for roughly 13% of the total CO2 emission in the E.U. From 2021, the CO2 emissions of new passenger cars must be reduced by 27% compared to 2015.

Sustainable process oil in SBR tire tread formulations
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.
