Brazil: A study has successfully enhanced the insulation properties of styrene-butadiene rubber (SBR) composites by incorporating micronised leather shavings. In a report published in the Journal of Materials Research and Technology, Gabriel Deltrejo Ribeiro and his team concluded that the new SBR-leather composite insulation had a thermal conductivity of 0.073W/mK and achieved a temperature attenuation of about 15°C.
