Mixing

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.

In this study, several modifications were made to an NBR based work boot outsole compound, and the compounds were subjected to a variety of abrasion tests.

Custom rubber mixers are listed, along with plant locations, equipment, mixing capabilities and whether technical service and/or recipe development are offered. A directory of companies that offer various custom services to the rubber industry follows.

Many methods exist to predict low temperature performance of
elastomers, such as the glass transition temperature (Tg) from
differential scanning calorimetry (DSC), dynamic mechanical
analysis (DMA), as well as lot temperature regraction, Gehman
torsional and compression set tests.

The following directory lists custom services suppliers. The first part lists custom rubber mixers along with plant locations, equipment, mixing capabilities and whether technical service and/or recipe development are offered.

NR is usually masticated for viscosity reduction through breakdown of the long molecular chains to facilitate subsequent processing steps (e.g., extrusion and calendering) and improve rheological properties, such as die swell, shrinkage and building tack.
