Characteristics & Advantages

·Tolerance to extreme surface finishing conditions, such as "ascast" 
·Conformable to flanges with higher "out-of-flatness" values, such as stamped steel and plastic covers .
·Lower bolt torques possible. 
·Fewer fasteners in the system. 
·Smaller or lower grade fasteners. 
·Components with less mass and more distortion 
·Stable damping values across the frequency range reducing vibrations effectively 
·Easy to fabricate
