Patent No. EP3470457 (titled "Sulphur-Linkable Rubber Compound, Vulcanizate Of The Rubber Compound And Vehicle Tyres") was filed by Carl VON Ossietzky Universitt Oldenburg on Oct 10, 2017. The application was issued on Sep 20, 2023.
Patent Summary
Sulfur-crosslinkable rubber mixture for vehicle tires that contains renewable replacement filler made from hydrothermal carbonization (HTC) of biomass instead of fossil-based carbon black. The HTC filler has lower carbon content but similar rigidity to carbon black. The mixture also contains diene rubbers, plasticizers like liquid polymers and hydrocarbon resins, and other fillers like silica and industrial carbon black. The HTC filler amount ranges from 30-80 phr, allowing up to 50% renewable filler content in the tire. The mixture is produced by mixing all components except sulfur in stages, then adding sulfur in a final stage.
