Ultramid® Expand is a particle foam by BASF that is based on a combination of several polyamide 6 grades. The particle foam consists of pre-foamed particles with a defined particle size and density, which can be welded into a 3D component without generating foam waste in a molding machine. The component has isotropic foam properties, i.e. the same mechanical properties in all directions. A chemical reaction does not take place in the foam.

Properties:

 High heat deflection temperature
 High temperature resistance
 Excellent mechanical properties at temperature >120 °C
 Chemical resistance against automotive liquids
 Drop-in solution in EPP tooling (steam chest molding)
 Recyclability
 Simulation models available
 Processable via cathodic dip coating
