ETN-Cell-VU is a micro-fine foam based on Desmodur 15, which is characterized by its special physical properties. It is therefore particularly suitable for use as a spring and damping material. The progressive spring characteristic results in the special damping behavior. ETN-Cell-VU is characterized by: high elasticity, low compression set great restoring force - even after long exposure volume compressibility at low transverse strain resistance to grease, oil, gasoline and ozone very good tear and tear propagation resistance excellent cold resistance long travel (up to 90% of Height) The production takes place both as a plate product, as well as a molded part. Thinner plates in almost any thickness are made from thick blocks by splitting, which can be further processed by water jet cutting. ETN-Cell-VU has excellent volume compressibility because of its cellular structure. All other elastomeric spring materials are nearly incompressible, i. These materials allow only a limited travel at constant volume. With unrestricted transverse strain, such as compressive stress between two parallel plates, there is a significantly smaller increase in the diameter of ETN-Cell-VU compared to rubber. Due to the cell structure compression goes so far until all cells have disappeared and a homogenous elastic structure is reached. These properties allow you to construct spring elements that allow up to 90% of their overall height as spring travel.
