Zeon Europe GmbH – European subsidiary of Zeon Corporation, Japan, a globally operating producer of specialty polymers – introduced several new specialty rubbers at the Deutsche Kautschuk Tagung (DKT; German Rubber Conference) and International Rubber Conference (IRC) in Nuremberg, Germany, June 27-30, 2022, a triannual international major event for the rubber industry.
“In response to the increasing demands on polymer materials, we have developed a range of new high-performance materials that feature enhanced performance, reduced carbon footprint, and improved resistance to new types of automotive service fluids and media”, said Hubert Thimm, Commercial Director of Zeon Europe GmbH.
According to the company, with the new Bio-Hydrin Eco, Zeon supports its customers in reaching the goal of reducing the CO2 footprint of elastomer products. The epichlorohydrin monomer used by Bio-Hydrin is derived from the by-product of biodiesel production originating from sustainable agricultural sources. Bio-Hydrin fully maintains the properties of standard Hydrin based on crude oil sources. The substitution with 1 kg Bio-Hydrin may reduce the carbon footprint by the equivalent of up to 2.56 kg CO2 (based on calculations by the producer of bio-epichlorohydrin). Application areas include many automotive and industrial components.
In addition, Zeon has added new grades to the HyTemp ACM polymer range. The new HyTempH570 is said to offer improved low temperature performance and good fluid resistance whilst providing the same high temperature resistance characteristic of HT-ACM. The family of ACM elastomers known as high temperature polyacrylate (HT-ACM) use the most heat resistant ACM technology to date. Therefore, they have better heat resistance than traditional ACM materials due to optimization of backbone monomers, along with improved cross-linking technology, said the company. HyTemp ACM has long been established in the automotive market for sealing and gasket applications as well as for hose applications for air and fluid management systems of the engine. Their resistance to high temperature and automotive fluids makes them ideal for use in e-mobility sealing applications.
Furthermore, the new Hydrin DP5227 and DP5250 grades complement the Hydrin HT-Eco series for enhanced processing and increased upper temperature resistance compared to Standard Hydrin Eco copolymer and terpolymer grades. In addition, they provide several cure system options including Sulphur and Peroxide, as well as Triazine and Bisphenol for flexibility in moulding, calendaring and extrusion processes, and balance of properties. The wide range of applications embraces automotive sealing and fuel hoses as well as industrial components such as diaphragms and oil hoses.
