Hutchinson innovates to slash carbon emissions without compromising performance for automotive sealing

RubberWorld 249 Views

Hutchinson’s solution involved the creation of two new materials: revea® TPE 428, which contains 37% biobased, biosourced, or recycled ingredients, and revea® TPE 426, which contains 29% biobased, biosourced, or recycled ingredients. These materials deliver the desired properties for various window seals, offering substantial CO2 savings—25% reduction with revea® TPE 428 and 16% with revea® TPE 426 compared to traditional materials.

Reduction of zinc oxide in 10 compounds of a model passenger car radial tire

RubberWorld 331 Views , 

Excess zinc in the body of living organisms is problematic in nature, and zinc primarily enters the environment through rubber articles, including disposed tires. Work done to minimize the amount of zinc oxide consumption in 10 compounds of a typical passenger car tire is explained by the author.

Structural adhesives composed of epoxy resins and hydrogen bonded styrenic block polymer based TPEs

RubberWorld 296 Views , 

A wide range of polymer materials with excellent performance and functionality has been developed in recent years to address diverse and complex material applications. Adhesives are one such example of these polymer materials. In general, adhesives are composed of a liquid substance (prepolymer) that is first used to fill in the rough surface of one substrate, and then the adhesive on the substrate is sandwiched by another substrate. Polymerization and crosslinking of the prepolymer in the adhesives are induced by heat or other external stimuli, leading to curing of the adhesives between substrates.

UNC researchers pioneer chemical process to repurpose rubber waste

RubberWorld 329 Views

The University of North Carolina at Chapel Hill researchers introduce a sulfur diimide reagent that enables the installation of amine groups at specific locations in the polymer chains. This step is crucial because it sets the stage for the subsequent backbone rearrangement. This chemical reaction reorganizes the polymer backbone, breaking down the rubber into soluble amine-functionalized materials that can be used to produce epoxy resins.

The researchers showed that their two-step process works very well. In a test with a model polymer, they broke it down significantly, reducing its molecular weight from 58,100 g/mol to about 400 g/mol. When they applied the method to used rubber, it broke down completely in just six hours, turning it into a soluble material with amine groups that could be used to manufacture broadly useful materials like epoxy resins.
