Bridgestone Americas (Bridgestone) and Dow recently announced that they have partnered to develop B-Seals, a silicone-based tyre sealant. According to the two companies, B-Seals can be efficiently separated from tyres to promote tyre repairability after a puncture. In addition, the technology is designed to enable end-of-life tyre recycling and extended tyre life.
Bonn District Court and the higher Federal court of appeal in Cologne have rejected the application for a preliminary injunction against Ultra-Seal regarding the use of Ultra-Seal on the German market sought by the German tyre association BundesReifenVerband (BRV). According to the company, over the last few months, a large lobby had been set up by the BRV, which had been “proactively attacking Ultra-Seal users and the press with statements about Ultra-Seal being illegal on the German market on grounds of §36 of the StVZO (German Road Vehicle Registration Regulations) under ‘Richtlinien’ (guidelines) issued by the Bundesverkehrsministerium (Federal Transport Department)”. Ultra-Seal stated its counterarguments against these allegations in statement published by Tyres & Accessories’ German sister website, Reifenpresse on 23 May 2017.
