Ultramid® Expand
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.
The particle foam excels with a wide range of unique characteristics: high temperature-resistance, outstanding stiffness and strength as well as an excellent chemical resistance, e.g. in contact with fuels, oils and lubricants. Additionally, the closed cell foam structure offers an exceptional compressive strength, a requirement for the use in crash relevant components that are exposed to high mechanical demands. Because of this versatility, lightweight applications are possible as well.
