Member company, LANXESS Corporation, just announced a really cool new polymer that can withstand harsh chemical environments. Check out this news release!
THERBAN® XT HXNBR is a high modulus, strong and robust polymer designed to withstand explosive decompression and harsh chemical environments such as in oil well drilling applications.
The THERBAN® XT polymer has a variety of characteristics, especially at high temperatures, which make it useful in many demanding applications. With its excellent adhesion to metals, plastics, natural and synthetic fibers, it is beneficial for high performance belts. The compound’s high hot tear
strength makes it suitable in rubber components for tough engineering applications, and the high abrasion resistance of THERBAN® XT polymer makes it useful for rubber rolls, shaft seals, and track pads.
“THERBAN® XT’s amazing ability to perform under such extreme conditions makes it the ideal product grade for a wide-range of products that demand performance under any condition,” said Victor Nasreddine, Ph.D., from Technical Rubber Products Application and Business Development, LANXESS Corporation.
Compared with regular HNBR and other synthetic elastomers, THERBAN® XT compounds exhibit unusually high tear strength at high temperatures, better abrasion resistance and have higher tensile strength and higher elongation at break at high temperature.
When THERBAN® XT polymer is blended with regular THERBAN® HNBR in the presence of ZDA (Zinc Diacrylate) in a peroxide cured compound, mechanical properties, adhesion, and Pico abrasion resistance are increased, while maintaining very good low temperature performance. Such compounds also maintain high levels of mechanical properties at operating temperatures above 130° C (266° F).
To create THERBAN® XT, LANXESS uses a highly selective catalyst that hydrogenates only the C=C double bonds of a carboxylated nitrile rubber (XNBR). This highly controlled process preserves both the functionality and the random distribution of the XNBR carboxyl moieties. It can be crosslinked by either peroxide or sulphur cure systems.
