In December 2015, the United Nations Climate Change Conference was held in Paris. The conference negotiated the Paris Agreement, which is a global agreement on the reduction of climate change. At the follow-up climate change conference in Marrakech (COP22) in November 2016, the member states of the Kyoto Protocol agreed to set the goal of limiting global warming to a still acceptable level of less than 2°C compared to pre-industrial levels. This target requires that the zero emission of CO2 is achieved soon.

Developing tire tread formulations for electric vehicles (EVs) presents a unique challenge. Instantaneous high torque and vehicle dynamics demand traction performance, while owner expectations for battery life and range highlight the need for very low rolling resistance compounds. In addition, vehicle weight and new environmental pressures increase the need for improved durability and abrasion resistance.

Use of treated silica as a filler in passenger, truck and bus tires is explored, including how using treated precipitated silica can overcome manufacturing limitations associated with conventional high dispersible silica/in situ silane technology.

The TRP Reworker is a resource saving technology for the economical processing of rework materials based on the two-roll plasticizer (TRP) with integrated Roll Ex gear pump. In an automatic process, unvulcanized rubber compounds are processed particularly gently and continuously in order to return this rework material to the production process. In tire production, compound waste is unavoidable due to the process.
