Floods in Southern Thailand damage over 12 million acres of rubber plantations

Massive floods have hit five provinces in the Southern Thailand last week and have caused estimated damages worth 20 billion baht ($589 million USD), the Rubber Authority of Thailand (RAT) said.

University of Virginia researchers solve a nearly 200-year-old challenge in polymers

Researchers at the University of Virginia School of Engineering and Applied Science have developed a new design that appears to rewrite the textbook on polymer engineering.

“We are addressing a fundamental challenge that has been thought to be impossible to solve since the invention of vulcanized rubber in 1839,” said Liheng Cai, an assistant professor of materials science and engineering, and chemical engineering.

That’s when Charles Goodyear accidentally discovered that heating natural rubber with sulfur created chemical crosslinks between the strand-like rubber molecules. This crosslinking process creates a polymer network, transforming the sticky rubber, which melts and flows in the heat, into a durable, elastic material.

Ever since, it’s been believed that if you want to make a polymer network material stiff, you have to sacrifice some stretchability.

India’s manufacturing slowed in November

India’s manufacturing growth slowed in November, marking its weakest level in 11 months due to price pressures and softer domestic demand. The HSBC India Manufacturing Purchasing Managers Index (PMI), compiled by S&P Global, recorded a reading of 56.5 for November, down from 57.5 in October and matching September’s level. Although the PMI remained above the 50-point threshold indicating expansion, it was below the preliminary flash estimate of 57.3, reflecting a more subdued rise in factory orders and production. Input costs rose at their fastest pace since July, driven by higher prices for chemicals, cotton, leather, and rubber.

GRI strengthens global presence through key international exhibitions

GRI has further cemented its global footprint by participating in three prestigious exhibitions spanning three continents in the first week of November. Movimat in Brazil, EIMA in Italy, and SEMA in the United States. These events served as dynamic platforms for GRI to showcase its state-of-the-art tire technologies, engage with industry leaders, and establish new partnerships, underscoring its commitment to innovation and sustainability.

Bridgestone Battlax Hypersport S23 selected as original equipment for Ninja 1100SX

Through long-term tire co-creation development with Kawasaki Motors, Bridgestone continues to support the company by delivering value in its wide range of motorcycles. The BATTLAX HYPERSPORT S23 tires to be supplied as original equipment on the new Ninja 1100SX are next-generation sports tires that have exceptional performance across all areas necessary for sport riding without compromise.2 These tires feature a new pattern design meant to balance optimal changes in contact patch stiffness with excellent water drainage properties for riding on wet surfaces. Combined with optimized tire shape and construction, these characteristics support the new riding experience delivered by the Ninja 1100SX through enhanced grip and handling stability during straight-line riding and at large lean angles, delivering an elevated sport riding experience offered by the Ninja 1100SX.

Freudenberg-NOK Sealing Technologies acquires Toledo Driveline, LLC

Freudenberg-NOK Sealing Technologies announced that it has acquired Toledo Driveline, LLC., an Ohio-based aftermarket company that specializes in electronics and select hard parts for the aftermarket industry. The sale, part of a purchase agreement the company signed earlier this month with Seal Aftermarket Products (SAP), LLC., offers Freudenberg Sealing Technologies direct access to original equipment-quality electronic parts produced for aftermarket customers. Toledo Driveline will be integrated into Freudenberg Sealing Technologies’ Corteco Division. The financial terms of the SAP-Toledo Driveline transaction were not disclosed.

Utilization of AI driven solutions for rubber compound formulation: A practical approach

The integration of artificial intelligence (AI) into various industrial sectors has spurred remarkable progress in the field of manufacturing process development. This concept has been extended to polymer compound formulations, where AI techniques have been used to optimize rubber formulations as well. Furthermore, it is conceivable that mixtures of other polymers, such as TPEs, thermoplastic materials or polyurethane compounds, could be similarly treated. Advantages of employing AI driven tools include reduced development time, enhanced efficiency and increased accuracy.

U.S. Medical Glove Company launches U.S. Medical Accessories division

U.S. Medical Glove Company (USMGC) announced the launch of a new division, U.S. Medical Accessories (USMA), to support its growing business of building proprietary medical exam glove-making machines.

The new division, USMA, will exclusively supply USMGC customers with support and service for its machines. This includes supplying the parts, components, robotic tooling technology, laser cutting systems, custom electrical panels, and additional accessories required for manufacturing nitrile and polyisoprene exam gloves.

Smithers invests in simulated on-vehicle acceleration testing machine in Suzhou laboratory

Smithers has announced that it has invested in a state-of-the-art simulated on-vehicle acceleration testing (SOVAT) machine. This new testing capability was recently launched at the Smithers Suzhou, China laboratory with full machine demonstrations and tire testing training for attendees.

The SOVAT machine is the result of working with vehicle and tire manufacturers to understand their tire testing pain points. On-vehicle tire testing can be time-consuming and inconsistent, driving the need for faster, more repeatable methods for treadwear, chip and chunk, road hazard endurance, and break-in testing. With the SOVAT machine, clients now have an indoor, repeatable option to conduct this testing, providing results in a fraction of the time.

Freudenberg Sealing Technologies advances the development of in-wheel motors with patented seal design

For Freudenberg Sealing Technologies the advantages of in-wheel motors (IWM) extend beyond the passenger car segment. The company offers a patented sealing geometry to support original equipment manufacturers (OEMs) and manufacturers of electric motors ranging from electric cars to commercial vehicles right at the development stage.
In-wheel motors for electric vehicles offer numerous benefits: Components such as transmissions, brakes, and suspensions can either move much closer to the point of power transmission or be completely eliminated. The decisive advantages of vehicles equipped with IWM include wheel-specific torque control, enhanced comfort and more design space within the vehicle. This results in a better driving experience, greater range and more flexibility for developers.
In-wheel motors are also interesting for buses due to their lower center of gravity, tighter turning radius and higher load capacity. They can also offer added value as a combined trailer drive for e-trucks or as a generator for refrigerated trailers with independent power supply.

New Engineering Research Center coming to OSU to study natural rubber

The U.S. National Science Foundation (NSF) announced a 5-year investment of $104 million, with a potential 10-year investment of up to $208 million, in four new NSF Engineering Research Centers (ERCs) to create technology powered solutions that benefit the nation for decades to come.
One of the four new centers is TARDISS: Transformation of American Rubber through Domestic Innovation for Supply Security. The Ohio State University (OSU) partnered with Caltech, North Carolina State University, Texas Tech University, the University of California Merced, Rensselaer Polytechnic Institute, and Case Western Reserve University for this new center. This makes OSU the only university in the nation to lead 2 ERCs simultaneously. Faculty members in the Food, Agriculture and Biological Engineering Department led the effort.
