Elastomer Fillers

22 Mar 2019

Organised by the IOM3 Rubber in Engineering Group

This afternoon technical discussion meeting (ATDM) examined the development of new advanced fillers with functionalised surfaces that can interact with the polymer network in the elastomer. The four presenters (left to right: King, Meyer, Kępas-Suwara, Tunnicliffe) are show at the end of the event.

Introduction - Prof James Busfield

Opportunities for Functionalized Carbon Blacks in Rubber Applications (PDF 2.6MB)- Lewis Tunnicliffe & Charles Herd (Birla Carbon, USA)

Strategies for functionalisation of carbon black were discussed together with experimental data on the use of highly functionalized carbon blacks in tire applications. Oxidized carbon blacks can be combined with suitably functionalized elastomers (e.g. XsSBR, Li-BR, ENR) or compatibilizer chemicals to achieve differentiated performance. This is particularly important given increasing pressure on tire manufacturers for reduced rolling resistance.

The effect of plasma functionalisation on nanomaterial fillers in elastomeric compounds (PDF 1.9MB) - Michael King (Haydale, UK) 

The benefits that plasma functionalised nanomaterials can have on elastomer properties was discussed, with data highlighting the different performance uplifts that can be achieved with low loadings of functionalised nanomaterial fillers in different elastomeric compounds.

Surface-modified Flame Retardant (PDF 1.7MB) - Melanie Meyer (Behn Meyer Europe GmbH, Germany)

Flame retardant chemicals such as Alumina Trihydrate (ATH) are usually non-reinforcing when added to elastomers, requiring the addition of other functional fillers when a reinforced elastomer is required for the application. Through the modification of the surface, ATH and other flame resistant materials can be made semi-reinforcing and compatibility with catalyst cure systems increased.

Visualisation of the polymer filler interface using atomic force microscopy (PDF 1.2MB) - Anna Kępas-Suwara, Stuart Cook, Paul Brown & Vincenzo Orlando (TARRC, UK) 

This study reported the direct visualization and nano-mechanical characterization of the interface between the filler and the polymer in elastomer composites using Atomic Force Microscopy (AFM) based techniques. The bulk mechanical properties of these composite materials are greatly influenced by the behaviour at this interface. Compounds ranging from model compounds to ‘full’ tire tread formulations are reviewed.

This event was championed Joe Hallett of Birla Carbon. It was free to attend due to the generous sponsorship of the RIEG Technical Programme by ARTIS.
