TARRC's Paul Brown to give ENR paper at Rubber Seminar

Paul Brown to give paper at MPG Seminar at the LCCTARRC's Paul Brown, Head of the Advanced Materials & Product Development Unit, presentaed a paper entitiled: 'Epoxidised Natural Rubber: The Green Alternative to Synthetic Rubbers in Tyre Applications' at the Manchester Polymer Group's (MPG) 5th Annual Rubber Seminar 'Bouncing Back!' on Monday 17th May 2010 at The Red Rose Suite at the Lancashire County Cricket Club.

Paul Brown's presentation gave a detailed background on Epoxidised Natural Rubber (ENR) and its properties and will cover recent research into passanger tyre tread formulation carried out at TARRC. Dr Andrew Tinker, TARRC's former Director of Research also presented a paper at the seminar.

The MPG is a local group of The Institute of Materials, Minerals and Mining and will be holding it's 18th AGM after the seminar. The seminar is sponsored by Columbian Chemicals - provider of high-quality carbon black.

The meeting was well attended with local members traveling from as far as Cockermouth in the Lake District to attend. The topics covered ranged from elastomers as variable resistors in electronic circuits through recycling of rubber and the current position on REACH and new hazard classification regulations.

The REACH talk disclosed how few chemicals currently had documents submitted considering the approaching deadline of December 1st. The speaker also raised the impending changes to chemical hazard classification (CLP regulations Classification, Labelling and Packaging), due to come into force in 2 stages: pure substances in 2011 and mixtures/ preparations in June 2015. This dual entry timetable will mean that for the intervening period both systems will be required for pure substances.

Martin Bennet of Artimis described how a TMS rheometer could be used to study the effect of mould release agents and mould surface material on demoulding, particularly from long mandrills. By curing the compound inside the TMS rheometer and then starting the rotor, the force to break the adhesion to the mandrill and also the sliding friction in removal could be measured. Thus the optimum combination of release agent and mould surface could be determined. Sadly, the wear resistant coatings gave the highest friction.
