Presentation Abstract

Liquid rubber in automotive lightweight body design - Improved crosslinking, product performance and sustainability

In automotive vehicles, elastomeric adhesives and sealants contribute strongly to entire car constructions and performances. They provide a safe method to join firmly metal surfaces while exhibit flexibility to withstand temperature changes or vibrations. In addition, the production of innovative solutions is continuously increasing as through the development of these materials can effectively achieve the future mobility and transportation trends: emissions & noise reduction, performance & safety improvement, light weighting, interior air quality, greater comfort, and lower costs.

Kuraray Liquid Rubber is a synthetic rubber based on isoprene, butadiene, and styrene at the polymer backbone and partially functionalized at the side chains to improve the adhesion to polar phases. They show molecular weights ranging from 5,000 to 50,000 g/mol with narrow molecular weight distributions and can be cured with different systems. We will present the advantages & disadvantages of the crosslinking of rubber-based compositions by each system, as well as their potential applications within the industry in terms of adhesion, toughening and damping performance.
