摘要：
The shrinkage and warpage behavior of polymers is governed primarily by the temperature profile and their pvT behavior. Oversimplification in the description of the material results in an inaccurate prediction of the temperature profile and hence in an inaccurate prediction of the shrinkage and warpage behavior too. The influence of pressure and temperature on the thermal conductivity and specific heat capacity and the influence of the cooling rate on the pvT behavior are, however, significant.
