The silicone rubber used is age-resistant and has an increased working temperature range. Due to the material purity, use is possible in the food and medical industry. They absorb most of the accumulated kinetic energy on impact. They act as dampers and prevent damaging shock and rebound. They also act as sound dampers. These mounts are also used as set-up elements and leveling feet.
