They absorb energy from the irregular road events, support vehicle handling requirements, and have excellent damping characteristics. Vibracoustic can offer multiple MCU material and design options, including assembly with bumpers, dust covers, saturation cups or in complete air springs. Another benefit of using Micro Cellular Polyurethane (MCU) is that it can be easily tuned and optimized simply by changing the material’s density. Once the geometry is developed through our standard FEA methods, there is usually no need to change chemistries, or part geometry, which results in a cost and time efficient development process. About MCU Components Micro Cellular Urethane (MCU) components combine maximum performance, high comfort and lightweight versatility. The material provides superior abrasion, tear and chemical resistance along with high tensile strength and a low compression set. It is also resistant to automotive fluids and ozone. MCU components are used for jounce bumpers, spring aids, spring seats, bushings, top mounts, and body mounts. more Related Products MCU Top Mounts MCU Spring Aids MCU Spring Isolators Downloads Code of Conduct Documents for Customers Documents for Suppliers Imprint Data Protection Legal Notice Follow us on Contact us Jobs & Career Products & Services Suppliers & Service Providers Vibracoustic Aftermarket Our Locations Media Compliance The website uses cookies to allow for the best possible user experience.
