Electrically powered vehicles: Impact of new fluids on sealing components

RubberWorld 1153 Views , 

A lack of conventional energy resources and the associated consequences have led to a shift towards e-mobility in society in recent years. This has changed the requirements profile for Tenneco sealing components for electric drive compared to the traditional combustion engine. Figure 1 shows the change in the requirements profile. As such, Tenneco investigated the influence of these new requirements on its current elastomer portfolio in order to provide tailored materials for e-mobility applications, such as sealings for high voltage and electric components in, e.g., battery electric vehicles (BEVs) or fuel cell electric vehicles.

SureMix S6 for process stability improvement in high silica tire tread compounds

RubberWorld 949 Views

Silica first found its way into elastomers as a filler in the 1950s, when it was used in shoe soles. By the 1970s, its use quickly expanded, as silica began being tested in heavy truck tires, passenger tires, engine mounts, gaskets and other rubber products. This expansion was due to growing information supporting its ability to increase adhesion, lower heat buildup and increase tear resistance. It was not until the early 1990s that Michelin proved in a commercially viable manner that the combination of precipitated silica and silane in a tire tread composition resulted in lower rolling resistance and increased wet traction.

Wacker expands production of silicone sealants at Nünchritz site

RubberWorld 697 Views

In response to growing demand, the WACKER chemical group is expanding its production and cartridge filling capacities for silicone sealants at its Nünchritz site. The expansion will increase the company’s capability to supply customers, who contract WACKER to produce ready-to-use silicone sealants for their direct sales. Some €20 million has been budgeted for the new manufacturing lines, which are scheduled to begin production in the fall of 2024. Construction is expected to start before the end of this year, subject to approval from the regulatory authorities involved. The expansion project will create additional new jobs at the site.

Silane modified low molecular weight liquid polymers in sulfur cured mixtures of styrene butadiene copolymers and silica

RubberWorld 2407 Views , 

Global emissions of greenhouse gases from trucks and passenger cars are influenced by the deformation energy and friction losses of tires. It is mostly associated with the rolling resistance between the tire tread and the road surface. For this reason, the rolling resistance is considered one of the most important performance indicators (that is, targeted to be reduced) within the tire industry.
