WHEN IT COMES TO VIBRATION TECHNOLOGY
Due to its mixed cellular structure, Vulkocell® is the powerful counterpart to the massive Vulkollan®. Due to its excellent material properties, this elastomer is preferably used where a much higher deformation at a low compression hardness compared to solid elastomers has to be achieved. Vulkocell® is manufactured in a volume weight between 300-700 kg/m3 (special densities on request).
Due to its microcellular structure, Vulkocell® is highly volume-compressible at a very low transversal strain. This advantageous combination, supplemented by a relatively low damping and a high dynamic load capacity offers a variety of applications in the field of general machine construction and vehicle constructing industry.
Relatively low damping and high dynamic load capacity: With this advantageous combination, solutions made of Vulkocell® are used around the globe to solve vibration problems, for example for maximum safety, suspension and comfort in vehicle construction.
In addition, Vulkocell® is characterized by its resistance to aliphatic hydrocarbons such as oils and grease, as well as to ozone and aging. In the technical field a general resistance to lubricants can be assumed. In case of lubricants containing certain additives, a test under operating conditions should be carried out. If needed, special adjustment to protect against hydrolysis can be arranged.
The shear modulus of Vulkocell® is almost constant from -10 °C to +120 °C. Its deformation behaviour remains equal in varying temperatures - which is often a decisive criteria for the material selection. Another advantage is the good flexibility even at low temperature: only below -30 °C a hardening occurs. The permissible operating temperature of heat is 80 °C. Short term temperature up to +120 °C is possible. Under dynamic long-term stress Vulkocell® changes its properties only gradually: Whether at room temperature or at 80 °C - the spring characteristic is always in the same order. Even after a million compressions, the permanent deformation is low.
