This follow-up to the 2022 International Elastomer Conference and Expo, held last month in Knoxville, Tennessee, and published for the Rubber Division, ACS by Lippincott & Peto, Inc., includes photographs and summaries of IEC events, including the Rubber Division, ACS Service Award recipients, 2022 scholarship winners, the Experience Elastomers Student Outreach Program, nomination information for the Rubber Division, ACS 2024 Science & Technology Awards, 2022 Expo exhibitors, and details on future International Elastomer Conferences, including locations through 2029.
In a four-person household, the washing machine is in operation about one and a half hours a day. On average, it washes, rinses and spins about 250 times a year, cleaning some 1,000 kilograms of dirty laundry, an amount that is increasing all the time. Its components, particularly the rubber hose systems and rubber gaskets, are subjected to greater chemical and mechanical stresses than just about any other household appliance. Moisture, detergents and cleaning agents, particularly alkaline agents, as well as high water temperatures must not have an adverse effect on the material. Due to the long service life of the washing machine, all polymer parts, especially rubber parts, need to have a service life of at least 10 years, which means excellent resistance to aging.
Chemicals and Materials
Several products that can serve more than one purpose in rubber compounds are examined, including anti-reversion agents, dithiophosphates, curing activators and blowing agents.
The demand for performance and consistency of elastomer based compounds is growing quickly in all fields (tire, technical rubber goods, cables). Specifications regarding physical, mechanical and chemical properties, as well as “visual aspects” properties of the finished products are becoming more and more strict.
During compound production, all operations are involved, from the weighing to the storage of the semi-finished mixed compounds. The mixing operation plays a very important role, since it is the step where all ingredients are incorporated, dispersed and distributed.
Silicone & Medical
At the COMPAMED 2022 exhibition, HEXPOL TPE officially launched their medical TPEs with bio-attributed content according to the mass balance principle. Adding to their growing portfolio of materials that enable a shift away from fossil feedstocks.

Testing & Instruments
A new method to ensure consistency and quality in rubber manufacturing, developed by a research team from the University of Tennessee, Knoxville, and Eastman, is likely to show real-world impact on material sustainability and durability for products such as car tires.
Dow and Magnum Venus Products (MVP), a global manufacturer of fluid movement and production solutions for industrial applications, introduce a new polyurethane-enabled chemistry delivered by an innovative three component injection system using a unique Fast Flow Light RTM process. This innovative process for closed molding increases part production by decreasing injection times. The new technique is a blend of MVP’s Flex Molding Process and Light Resin Transfer Molding and utilizes collapsible resin channels for a faster resin flow.
Thermoplastic Elastomers & Urethanes
Thermoplastic polyolefin (TPO) is one of the fastest growing commercial roofing systems on the market. Developed in Europe in the 1970s, TPO was introduced to the U.S. market in the late 1980s and has become the dominant installed roof system in the industry; now used on 53% of commercial roofs, according to the American Institute of Architects.
Latex and Natural Rubber
Natural rubber masterbatch was aged at different temperatures, and the effect of aging conditions on masterbatch, final batch, Mooney scorch and cure characteristics, and cured sample was studied.
