Goldsmith & Eggleton LLC (G&E), a Ravago company, announced the completion of a year-long improvement plan for its carbon black masterbatch (CBMB) plant. These improvements have been designed to minimize the handling of carbon black and rubber in the mixer, improve ergonomics, and increase batch-to-batch consistency. The improvements to the plant are part of a long-term strategy to offer the marketplace with innovative polymer solutions with a focus on sustainability and a circular economy. In 2023 G&E achieved QA-CER system 2 certification.
Toyo Tire U.S.A. Corp. (Toyo Tires®) announces a new compound upgrade for increased milage to three existing long haul and regional truck tires, which include the Toyo® M171+TM, M671A+TM, and M677+TM. The improved compound change maximizes removal miles while maintaining low rolling resistance and traction. The new compound can result in improved mileage based on application, delivering more to the user’s bottom line.
In 1962, Mr Noorani joined Bayer (India) Ltd. and spent two years at the company’s complex in Leverkusen, Germany. This was the start of his three decades-long association with the company and an abiding affinity for the country and command of the language. Following a thorough induction into the field of rubber technology, in 1965, Mr Noorani was posted to Kolkatta, at Bayer (India) Ltd.’s Eastern Region for the Rubber and Chemical Divisions. He was transferred to the company’s head office in Mumbai five years later, initially attached to the Chemicals division, before moving to the Rubber Division in 1972 as Marketing Manager.
lastocon has developed a new model of its automatic relaxation and creep tester. The new EB 32 model has a liquid circulator for cooling and can cycle between -40 °C and +200 °C, with the same temperature in all 3 test stations. EB 32 can perform testing of rubber and plastics according to ISO 188 method A, ISO 3384-1 method A and B, ISO 3384-2, ISO 6914 method A, ISO 899-14 and ISO 899-2 with some modification (no extensometer required).
The original model EB 18-II-3 also has three test stations with individual control of each station. The temperature in each cell can also be controlled individually, between +40 and +200 °C (up to +300 °C in the HT version). EB 18-II-3 can perform testing according to the same standards, except ISO 3384-1 method B and ISO 3384-2.
The event includes a “behind the scenes” tour of the Trelleborg Stein am Rhein production facility in Switzerland, providing an insight into its high-precision production processes – including under cleanroom conditions – and an interactive platform for experts and industry peers to share ideas.
The rubber compounding arm of the HEXPOL Group has announced an investment in a devulcanization line in Europe. This allows them to offer mechanical devulcanization of rubber in-house and supports the transition to a circular economy. The new extruder will be installed at the HEXPOL Compounding site in the Czech Republic year end 2024, where it will provide devulcanization services also to the other European HEXPOL Compounding sites to ensure that a broad customer base can join the circle
Pyrolysis has been used as a means of recycling end-of-life tires or other post-industrial and/or consumer rubber products for several years. This process produces several valuable secondary raw materials that support the circular economy. One such material, sustainable carbonaceous material (SCM), can be used as a sustainable alternative to carbon black in many applications where traditional virgin carbon black is used. Although traditionally seen as suitable only for low value applications, recent advances allow the use of SCM in a wider range of higher value products. These advances are helping compounders and OEMs meet their sustainability targets by allowing the use of a higher percentage of sustainable materials in their formulations with minimal adjustments or loss in performance.
Global emissions of greenhouse gases from trucks and passenger cars are influenced by the deformation energy and friction losses of tires. It is mostly associated with the rolling resistance between the tire tread and the road surface. For this reason, the rolling resistance is considered one of the most important performance indicators (that is, targeted to be reduced) within the tire industry.
A team at Sandia National Laboratories developed a molecule that helps change the way some materials react to temperature fluctuations, which makes them more durable.
Principal methods for processing elastomeric materials are reviewed, including continuous extrusion and what is described as multi-step extrusion.
The Global Automotive Silicone Market Size to Grow from USD 2.7 Billion in 2022 to USD 3.9 Billion by 2032, at a Compound Annual Growth Rate CAGR of 8.1% during the forecast period according to Spherical Insights & Consulting.

The TTS principle determines high or low frequency properties beyond the capability of dynamic mechanical tests.
Molecular Rebar in Aflas FEPM, when used in an Aflas compound formulation, results in improved tear toughness and high temperature modulus retention.
Researchers made a series of polymer gels with breakable bonds incorporated into different parts of the structure, and tested whether the properties changed after the gel was degraded and reformed.
The researchers hope this model system can be applied to other types of polymers, including adhesives, sealants and elastomers.
With disease and high demand posing threats to the world’s primary natural rubber supply in Southeast Asia, scientists are working to ramp up the U.S. rubber market by advancing methods to extract latex from two sustainable North American plant sources: a dandelion species and a desert shrub.
Researchers reported their methods to improve efficiency and increase latex yield in two recent publications, building upon decades of research led by Katrina Cornish, professor of horticulture and crop science and food, agricultural and biological engineering at The Ohio State University.
