Elastomer VT-AC-1005

VT-AC-1005 material is an engineered compound with Cork and Natural Rubber. This product is suitable for vibration control applications in need of very high isolation levels, used as discrete isolators (pads/strips) with a low resonance frequency and high load, such as: building bearings, separation of individual building parts, two-tier construction or crane runway bearings.

Selection Guideline

Material selection can be made using the Static/Dynamic E-Module in the respective load range or using the Vibration Isolation Level graph below:

Based on the machine/system disturbing frequency select the desired isolation level based on the material thickness and respective natural frequency for the specific load/ stress.
Determine the material compression from the deflection curve at the specific load/ stress.
Creep effect can be added to the above deflection via the Creep deflection graph calculating the additional deflection and adding.
