Combining the ESTANE® and Pearlthane™ thermoplastic polyurethane (TPU) portfolios with other engineered polymer specialties, Lubrizol represents a single, convenient and reliable source with multiple product groups for seals and gaskets. Lubrizol Engineered Polymers solutions helps solve some of today’s toughest challenges for these molded parts, even catering for the needs of fluid power seals that need to withstand extreme temperatures and physical wear and tear. Through their outstanding performance and mechanical properties, ESTANE and Pearlthane TPUs meet and exceed the requirements of highly technical parts that must be formulated with the highest quality materials available. With one of the lowest compression sets in their materials class, these resins are ideal for use in hydraulic seals and gaskets applications.
Using the specialty high-performance “H” technology for high pressure hydraulic seals, Pearlthane D11H92S and Pearlthane D11H95S TPU elastomers, feature high wear resistance, outstanding low compression set values and good flow properties. These TPU grades, especially developed for manufacturing hydraulic seals, are recommended for molded applications with an extremely short cycle time.
