Cushion and dampen: plastic disc springs

polysorb disc springs General properties Moisture absorption
The spring deflection of the disc spring is relatively small.
Low humidity absorption means that they can be used in

for many applications Disc springs are discs that can be axially loaded, Therefore a number of disc springs are combined in wet or humid environments.
