THE IMPORTANCE OF MIXING, MANUFACTURING AND MODULUS

We’re pleased to announce that, last week, we launched a brand new whitepaper and webinar which aim to raise awareness of the importance of ingredient selection, mixing and the manufacturing process in marine fenders.

Building on our previous research into ingredient selection and its impact on fender performance, the new materials highlight that compound modulus – the relationship between stress and strain in a cured rubber sample – is a far more effective and robust measure of fender performance than the traditional ‘hardness’, which is currently used in the industry.

The new research has proven beyond doubt the need for a new measure of fender performance, as ‘hardness’ is unreliable and can be easily falsified. As such, we suggest that the industry moves towards measuring the modulus of rubber compounds, to ensure the characteristics of the fender are truly understood.

Compound modulus is the determining factor of a fender’s performance, and highly impacted by the dispersion of filler in the rubber.  This dispersion, in turn, is dependent on the mixing process, the quality of which is determined by the machinery used.

We have discovered that even a superior rubber formulation – one which uses natural rubber and reinforcing fillers – can be degraded if it is subjected to an inferior mixing process, ultimately producing a low performance compound and a low performance fender.

The uniformity of filler dispersion within the rubber is critical: poor dispersion can lead to damaging effects such as reduced service life, poor performance, poor appearance and even poor product uniformity.

Our new whitepaper discusses the importance of the machinery used to mix the ingredients: there are a number of related parameters that affect filler dispersion in the final mix, including ram pressure, rotor speed and design, coolant temperature and sequence.

The new whitepaper explores which machinery options are most effective and give manufacturers the most control over these critical factors.

The webinar goes into more detail on the importance of measuring modulus, including an examination of filler dispersion in compounds produced by different mixing machines.

We’d love you to read the whitepaper, and watch the webinar – and let us know what you think of the new research in the comments.

LATEST BAROMETER SURVEY CALLS FOR MARINE INDUSTRY INSIGHTS

We’ve recently launched our latest Barometer Report survey, to gather views and opinions from across the industry on a range of issues from investment, to maintenance, to performance and downtime.

So if you’re a port owner, operator, contractor or consultant, we want to hear about your experiences.  By taking ten minutes to complete the survey,  you’ll enter a free draw to win an iPad.

Last year’s report revealed an anticipated boost in investment for facilities around the world, as well as an opportunity for ports to get ahead by investing strategically in smart technologies and supplier service, with a focus on improving long term product performance.

The findings from last years’ report also pointed to the need for more supplier involvement across the whole supply chain. This year, we’re keen to see if suppliers are closing the gap between the maintenance requirements of port owners and operators, and the support that they are able to provide.

And with increasing and varied demands on facilities, such as the anticipated rise in LNG bunkering and ever-growing vessel sizes, we’re particularly keen to see if infrastructure is keeping pace and if facilities have the support they need to evolve accordingly.
