- Foaming simulation of polyurethane systems now also available for car steering wheels
- Virtual process design improves air ventilation in molds and predicts foam density distribution
- Advantages for steering wheel manufacturers: faster component development and tailored, more reliable process
BASF has expanded its simulation tool Ultrasim® so that it can now precisely predict the foaming and curing of the flexible integral foam system Elastofoam® I for car steering wheels. With the detailed simulation, the most important chemical reactions as well as the flow behavior of the polyurethane foam in the mold can be calculated.
