From Virtual Foam Cell to Finished Component

Ultrasim Software Simulates Processing of Polyurethane Systems

From Virtual Foam Cell to  Finished Component

The properties of foams are primarily determined by their reactive processing. New simulation methods with wide-ranging material models are designed both to calculate the foaming process and predict the resulting foam properties. Specific examples already show extensive correlations between simulation and practice.
