BASF has introduced a particle foam based on a combination of several polyamide 6 grades. The particle foam excels with a wide range of unique characteristics like 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. Molded part densities can be adjusted across a wide range of 150 to 600 g/L. Because of this versatility, lightweight applications are possible as well.
Processable on Conventional EPP-molding Machines
“BASF continues its long tradition of developing particle foams. We started this project in close co-operation with our customer and now we can successfully produce various prototypes”, said Daniela Longo-Schedel, research engineer at BASF.
“Thanks to the temperature stability and adjustable mechanical characteristics, the particle foam is suitable for a wide range of applications. Furthermore, it can be effortlessly processed on conventional EPP-molding machines as well as with innovative water steam free technologies. We are working closely together with our customers to finalize the product development.”
BASF’s Ultramid® Grades
BASF’s Ultramid® grades are molding compounds based on PA6, PA66 and various co-polyamides such as PA66/6. The range also includes PA6/10 and semi-aromatic polyamides. The molding compounds are available unreinforced, reinforced with glass fibers or minerals and reinforced with long-glass fibers for special applications.
Ultramid® is noted for its high mechanical strength, stiffness and thermal stability. In addition, Ultramid® offers good toughness at low temperatures, favorable sliding friction behavior and can be processed without any problems.
