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

RubberWorld 258 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.

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

RubberWorld 313 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.

Continental develops a synthetic rubber to reduce hydrogen ion leakage

RubberWorld 563 Views

Continental has developed a line for cooling in the hydrogen powertrain of commercial vehicles, which considerably reduces the penetration of ions into the media circuit. The synthetic rubber line has a mixture of materials whose special properties make them less susceptible to the leaching of ions from the line material. This reduces the transfer of ions into the cooling circuit of hydrogen drive systems. The material experts from the group sector ContiTech have solved one of today’s greatest challenges in the industrialization of this still least common alternative form of drive system. The product innovation increases the service life of vehicle components in hydrogen drive systems.

1929 OM 665 Superba road trips 10,000 kilometers on Pirelli Collezione tires

RubberWorld 511 Views

A total of 10,400 kilometers were driven on Pirelli’s Stella Bianca tires – a reissue of the 1927 originals – with a car dating back to 1929 on a road trip to the most northerly point in Europe, without the need for a tire change. The epic journey was undertaken by a 1929 OM 665 Superba on Collezione tires, a range dedicated to historic collector cars from the 1920s to today. Setting off from Poggibonsi near Siena, the car driven by its owner Gianni Morandi and co-driver Marco Morosinotto, officially started its odyssey from Pirelli’s HQ in Milan. It arrived in Norway’s North Cape following a 15-day trip, returning to Italy after another two weeks. The whole adventure was undertaken using scenic routes, without a single kilometer of motorway. This was a landmark journey for Pirelli’s Stella Bianca tire, which has exactly the same vintage look as the original, but now uses materials and technologies that ensure greater safety.
