RFP - Rubber Fibres Plastics International

Ausgabe 02 | 2020



We really live in a very special time. We are experiencing how vulnerable so many things are that we previously thought were safe. We realize how fragile our lives are. Actually, this was already the case before Corona – we just always had enough distraction to keep us from looking. The value and importance of what we used to take for granted becomes clear: going to the office, visiting fairs and conferences, meeting friends, doing sports, hugging loved ones, ...

It is a time when many contradictory feelings arise in us. There is the fear for one’s own health and that of loved ones, the worries about financial and professional existence, the uncertainty whether we are on the right way and how to continue. But there is also the trust in us, the love for life, the joy about the “little” things and the confidence that everything has a meaning and that everything will be fine.

Everyone decides where to direct their attention and energy: to fear, in connection with greed, envy, egoism and resentment, or to confidence, tied to a sense of responsibility, trust, solidarity and love.

It is a crazy time - or maybe it is also a time for straightening things and standing up for what is really important to us.

It is a time in which everyone has to decide for themselves which way they want to go...

For my part, I feel a great gratitude for everything that has been given to me so far. Gratefulness for all the encounters in my life. Gratefulness for the opportunities that I have been allowed to seize again and again. Also gratefulness for being able to experience this time.

The team of the Dr. Gupta Verlags GmbH continues to be there for you. During this time, we are working to ensure that proven traditions are preserved and that new ideas are developed and allowed to grow.

Please remain loyal to us.

But most of all ... Stay healthy and positive!

Kind regards
Indira Gupta

From old tyres to new roads

Tyre Stewardship Australia (TSA), the Australian Road Research Board (ARRB), and the Victorian Department of Transport (DoT) have turned 1,600 used tyres into a 1.4 km road in Bentleigh, a suburb in Melbourne, Australia, using various mixes of crumb rubber asphalt. According to TSA, this project aligns with Vic Government’s Recycled First Policy and is another example of how good partnerships are helping turn a tyre waste stream into a resource.


Application of artificial intelligence in the compounding process

Artificial intelligence (AI) is on everyone’s lips. But what could concrete applications in production look like? This article will show concrete application possibilities using the example of a compounding process for elastomers. In this way, employees can be supported in the identification of root-causes and quality defects on the basis of data; in addition, time-consuming manual tests can be focused on critical batches. With the help of the standard model for data analysis CRISP-DM, the mixing process is viewed from the data glasses and analyzed in a structured way.

The global bio-based polymer market 2019 – A revised view on a turbulent and growing market

Turbulent times for bio-based polymers in 2019: PLA sold out despite expansion, as did PHA. Bio-based PP available for the first time, increased production of PBAT, PBS, bio-based PE, starch-containing polymer compounds and epoxy resins. Lower production is seen particularly in bio-based PET. At the same time, there is a lack of support from policy makers, who are taking bio-based and biodegradable plastics into collective punishment with fossil plastics in the Plastic Policy. These are some of the findings of the new market and trend report “Bio-based Building Blocks and Polymers – Global Capacities, Production and Trends 2019 – 2024” from the German nova-Institute. The report shows capacities and production data for all bio-based polymers in the year 2019 and a forecast for 2024. The market and trend report is written by the international biopolymer expert group headed by nova-Institute. The corresponding authors come from Asia, Europe and North America.

Methods for simultaneous dynamic-mechanical and dielectric analysis – Part 2: Temperature dependence of the dielectric behavior of elastomer composites under static deformation

Elastomer materials are often reinforced with electrically conductive fillers such as carbon black. The carbon black structures in the rubber matrix change under mechanical deformation and can therefore be used as “markers” for condition monitoring of elastomer components. Dielectric analysis is a suitable method for measuring this effect. In order to be able to use it for this purpose, it is necessary to know the exact correlation between the mechanical and dielectric properties of the material. The key to understanding this correlation lies in the use of simultaneous dynamic-mechanical and dielectric analysis, which is presented here in a three-part series. Part 1 (RFP 01 2020) dealt with the influence of a defined static mechanical deformation on the dielectric spectra of a carbon black filled hydrogenated acrylonitrile butadiene rubber (HNBR). Part 2 investigates the temperature influence on the dielectric spectra of a carbon black filled HNBR under static mechanical deformation.

A novel method for the optimization of sulfur cure systems for rubber using software

The goal of this study was to find a software approach that would make the optimization of the vulcanization system more efficient. For this purpose, a natural rubber (NR) was mixed with different amounts of elemental sulfur at ambient temperature to produce rubber compounds. Zinc oxide was treated with an organic accelerator to produce a convenient single material component to use as additive. The effect of an increasing loading of the surface modified zinc oxide on the cure properties of the sulfur-filled rubber compounds was subsequently measured at a high temperature in a curemeter. Using a JavaScript programme, the cure test results were processed to develop a highly efficient method for optimizing sulfur cure systems for rubber. All the essential information such as scorch and optimum cure times, rate of cure, crosslink density changes in the rubber, and chemical curatives requirement at a given loading of sulfur were subsequently provided for the user. This method removes the need to mix and test the raw rubber with chemical curatives repeatedly to find a compound with ideal cure properties for industrial applications.

Analysis of methods for measuring dispersion of fillers in rubber compounds

This paper will discuss the use of three techniques used to measure dispersion of fillers in rubber compounds. The three methods analyzed and compared in this study include: Phillips Dispersion test, Dispergrader test, and nSpec 3D topography scan. Physical properties of the compounds such as tensile strength, elongation at break, 100 % modulus, and tear strength, will also be compared. A simple SBR compound was selected for this study and five different fillers were evaluated. The fillers that were evaluated included three grades of carbon black (N234, N330, and N774) and two grades of silica (HiSil 190G and Zeosil 200 MP). This paper will also briefly discuss the advantages and disadvantages of the three different dispersion measurement techniques.
