1. Shrinkage
Although LSRs do not shrink in the mold, they often shrink by 2.5%-3% after demolding and cooling.
Exactly how much shrinkage occurs depends to some extent on the compound’s formulation, but from a mold perspective, shrinkage can be affected by several factors, including the temperature of the mold, the temperature of the compound when it is demolded, and the pressure in the m
