10,000Like other elastomers, Sylodamp®
exhibits increased deformation
under a static load (creeping).
This increase in deformation is
proportional to the time logarithm.
In other words, the additional
deformation that occurs is always
the same for each decade (1 day,10 days, 100 days, etc.). The largest
increase in deformation due tocreeping is completed after arelatively short period of time. The
areas of application for Sylodamp®
have therefore been selected sothat the creep curve is the same forall types.
