The Secretariat of the International Rubber Study Group (IRSG) publishes comprehensive data on production, consumption, trade and prices – covering both natural rubber (NR) and synthetic rubber (SR). On a biannual basis the World Rubber Industry Outlook (WRIO) presents the latest long-term forecasts for the next ten years, covering the world economy as well as the vehicle, tyre and rubber sectors.
The July 2020 edition of the World Rubber Industry Outlook (WRIO) is now available. The WRIO comprises three economic scenarios (IMF, Downside and Upside).
IRSG estimates, for the year 2020, a sharp decline in the global rubber demand by 12.6% year-on-year up to 25.2 million tonnes mainly because of the global pandemic. Containment measures including country lockdown, closure of factories and retail businesses and limited flow of labour and goods explains much of the downward trend in 2020 under the IMF Scenario. The global rubber demand is expected to rebound in 2021 (7.9%) driven by recovery in the tyre sector (6.9%) and growth in the non-tyre sector (9.3%) under the IMF Scenario.
World NR demand has declined by 1.0% in 2019 to 13.62 million tonnes. Under the IMF Scenario the growth is expected to decline by 11% in 2020, reaching 12.12 million tonnes. A recovery in NR demand (7.8%) is expected in 2021.
World SR demand has dropped by 1.0% in 2019 (15.18 million tonnes). Under the IMF scenario its growth is expected to decline by 14.0% in 2019, reaching 13.06 million tonnes. The SR demand is forecast to recover slightly faster (8%) than NR demand growth (7.8%) in 2021.

Researchers at the Fraunhofer Institute in Germany have developed a new type of synthetic rubber that they say is 50 percent less abrasive than natural rubber. So far, it has not been possible to use synthetic rubber for truck tires as synthetic rubber has not yet been able to match the abrasion behavior of natural rubber. Truck tires need very high levels of durability as trucks are driven for long distances over different types of terrains.

Researchers at the Frauhofer Institute said that the new type of synthetic rubber which is called BISYKA  is about 30-50 percent less abrasive than natural rubber. The initial tests of tires made from the new nature-identical rubber indicated that they were less abrasive than tires made with natural rubber. According to Dr Ulrich Wendler, who headed the project at the Fraunhofer pilot plant center for Polymer Synthesis and Processing PAZ in Schkopau, BISYKA is a German abbreviation for ‘biomimetic synthetic rubber’.

Researchers at the Fraunhofer Institute for Applied Polymer Research IAP, for Microstructure of Materials and Systems IMWS, for Molecular Biology and Applied Ecology IME, for Mechanics of Materials IWM, and for Silicate Research ISC, have been able to optimize the characteristics of synthetic rubber.

Scientists have considered many alternatives to natural rubber, including rubber sourced from dandelions and from guayule. Just like natural rubber, 95 percent of dandelion rubber comprises polyisoprene, wit the balance being made up of organic components like lipids or proteins. The key advantage that dandelion rubber has over tree rubber is that it has a generation succession of just three months while the rubber from trees needs seven years. Hence, dandelion rubber serves as the ideal starting point for exploring the influence of organic components on the characteristics of rubber.

Researchers eliminated each of the key organic components in a systematic manner and after they identified the organic components that played a role in abrasion behavior, the scientists at Fraunhofer IAP synthesized the BISYKA rubber out of functionalized polyisoprene with high micro-structural purity and the respective biomolecules. Their colleagues at Fraunhofer IWM and IMWS then used extensional crystallization to investigate the characteristics of the rubber variants. Wendler explained that the extensional crystallization of BISYKA rubber is the same as that of natural rubber.

During the manufacture of truck tires, the rubber that is used is generally mixed with carbon black. Lately,  however, many manufacturers are using silicates instead of carbon black. The researchers at Fraunhofer ISC investigate new kinds of silica fillers. Crystallization tests showed that tires made from the synthetic rubber lost 30 percent less mass than the tires made of natural rubber. The synthetic tires also showed only half the tread loss. Another advantage synthetic rubber offers is that it can be produced on an industrial scale using existing plants and equipment. This makes it an excellent alternative to natural rubber, even for the production of high-performance truck tires.

Prüflabor Nord then conducted a series of tests to analyze if the BISYKA rubber would do what its extensional crystallization promised. Four car tires made of tread using BISYKA were fitted on a real vehicle which was driven on 700 circuits in one direction and then 700 circuits in the opposite direction and the results were then compared with tests using tires made from natural rubber.

The tire made of natural rubber was 850g lighter after the test and lost 0.94mm of tread. The BISYKA tire lost only 600g and 0.47mm of tread. The rolling resistance of the synthetic rubber was also better: the natural rubber tire achieved a score of C on the EU tire label, and the BISYKA tire achieved a B.

“So far, we have only carried out initial tests with the BISYKA tire blend, but the results are extremely promising. As the next step, we want to further optimize the BISYKA rubber. This concerns, above all, the proportion and the composition of the organic components. At the same time, we will adapt the formula of the tread compound for truck tires to the new rubber,” concluded Wendler.

The team are currently seeking potential partners to commercialize the new synthetic rubber.

Yokohama Rubber Develops New Technology for Producing Isoprene from Biomass https://tiresandparts.net/news/tires/yokohama-rubber-develops-new-technology-for-producing-isoprene-from-biomass/ https://tiresandparts.net/news/tires/yokohama-rubber-develops-new-technology-for-producing-isoprene-from-biomass/#respond Sat, 04 Aug 2018 06:10:05 +0000 https://tiresandparts.net/?p=23951 Yokohama Rubber Co., Ltd., has announced that it has developed a path breaking technology for efficiently producing isoprene from biomass.

Yokohama Rubber Co., Ltd., has announced that it has developed a path breaking technology for efficiently producing isoprene from biomass. The new technology is the outcome of research that the tire manufacturer conducted jointly with RIKEN and Zeon Corporation.

The three partners started working on the project in 2013 and used computer-based in-silico metabolic design technology to discover the new isoprene-synthesizing process in 2015. Metabolic design technology is the term that is used for technologies that are used for designing new artificial metabolic reactions on computers.
The three companies further refined the new process which utilizes an artificial pathway and highly active enzymes to create cells which have excellent isoprene-synthesizing capability. The new technology is used to make cells which have the capability to generate isoprene from a biomass (sugar) that serves as the starting material. The in-vivo generated isoprene is then polymerized to achieve synthesis of polyisoprene rubber. The research project effectively leveraged the cell design and plant science technologies of the RIKEN Center for Sustainable Resource Science (CSRS) to develop this new technology.
Generally, isoprene is made naturally from mevalonic acid (an intermediate substance obtained from sugar) through a five-stage reaction, but the new artificial process that was developed through the joint research cuts this process down to two stages. The highly active enzymes involved in the process have a very high capacity to produce isoprenes that naturally occurring enzymes do not have. Colon bacilli bacteria into which this artificial pathway and these enzymes have been introduced develop an isoprene-generating ability that naturally occurring bacteria do not have and they can efficiently make isoprene through artificial synthesis. Yokohama Rubber confirmed that this very same technology can be used for butadiene-based synthetic rubber and other diene rubbers.

RIKEN is Japan’s only comprehensive research institution for the natural sciences. RIKEN CSRS is dedicated to the realization of a sustainable society through its research in the field of biological functions, especially its basic research on the effective use of plant-microorganism bioprocesses. Zeon, a manufacturer of synthetic rubbers, places its research emphasis on polymerization catalyst technology and enhancing the performance of synthetic rubbers. Yokohama Rubber is a comprehensive manufacturer of tire and rubber products and is actively engaged in research on utilizing biomass derived from plants, which is carbon-neutral (CO2 emission levels=CO2 absorption levels).
Isoprene is used as a raw material for the production of synthetic rubber (polyisoprene rubber) which is used for the manufacture of automobile tires and other applications. Currently, industrial isoprene is obtained as a by-product of naphtha pyrolysis. The development of this new technology for synthesizing isoprene will reduce dependence on petroleum and contribute to the reduction of carbon dioxide (CO2), which is considered a cause of global warming.

From the perspective of the small time rubber farmer, life has been a rollercoaster ride recently. After reaching a high of USD 3.982 per kilo in February 2012, the price of natural rubber declined steadily due to the global slowdown in the automotive industry and glut in the supply of natural rubber. More and more countries like China and Vietnam took to the cultivation of natural rubber on a large scale leading to a case of oversupply of natural rubber. With oil prices falling, the price of synthetic rubber which is made from compounds obtained from crude oil also started declining and this too contributed to the drop in demand for natural rubber. The situation has now undergone a sea change in recent months.

Thailand is one of the major producers of natural rubber, with the country accounting for almost 35 per cent of the global output of natural rubber. Massive floods which took place recently in the southern part of the country, where most of the rubber cultivation takes place, have had a severe impact on the

production of rubber. These widespread floods have affected infrastructure and transportation in as many as 12 of the country’s 27 provinces. The combination of drought and severe floods have taken a heavy toll on rubber farmers.

With demand set to outstrip supply, natural rubber prices have been zooming at an unprecedented rate. From January to January 2017, the price of natural rubber increased from USD 1.17 per kilogram to USD 2.22 per kilogram and this trend is expected to continue. With OPEC countries joining hands to cap the global supply of crude, the price of synthetic rubber has also experienced an upswing.

This is good for cultivators of natural rubber in other countries like Vietnam, Malaysia and India. However, tire manufacturers and retailers have been caught by surprise and are in a position where they are struggling to control costs without passing on the price increases to consumers. Many leading tire manufacturers like Goodyear, Michelin, Nankang, Deestone, Kenda, Zhongce Rubber Group and Kumho have had to increase tire prices in view of the price increases in the cost of raw material like natural rubber, synthetic rubber, carbon black and steel wire.

They have had to adjust their inventory levels of raw materials and finished products in light of the expectation that prices will increase even further. Obviously, no tire manufacturer would like to sell tires at a loss, but squeezed between the rising cost of raw materials on one side, and increasing competition on the other, this is definitely a moment of crisis for the tire industry.
