BASF introduced a foam particle based on the combination of different grades of polyamide 6. This material has many advantages such as high temperature resistance, high hardness and strength, and it exhibits excellent chemical resistance when in contact with fuel, oil and lubricants.
In addition, thanks to the closed-cell foam structure, the material's compressive strength is enhanced, and it can meet the use conditions of related collision components under high mechanical requirements. The density of plastic parts is between 150 and 600g / L, which can be used as a lightweight part.
Daniela Longo-Schedel, BASF`s research engineer, said: “BASF has continued its long tradition of developing granular foam and has now successfully produced various prototypes. Due to heat resistance and adjustable mechanical properties, this type of granular foam is widely used. EPP molding machine and innovative water-free steam technology can be easily processed. "
BASF's Ultramid® grade products are based on molding compounds of PA6, PA66 and various copolyamides (such as PA66 / 6). The series also includes PA6 / 10 and semi-aromatic polyamides. Such molding compounds include unreinforced products, and can also be reinforced with glass fibers or minerals, or reinforced with long glass fibers for special applications.
Ultramid® products are known for their high mechanical strength, hardness and thermal stability. In addition, it also has good low temperature toughness and sliding friction properties.
