Specialty chemicals company LANXESS has developed a new compound called Pocan AF4130 in collaboration with HELLA KGaA Hueck & Co., based in Lippstadt, Germany. It serves as a housing material for a battery management unit (BMU) and two cell monitoring units (CMU). The blend of polybutylene terephthalate (PBT) and acrylic ester-styrene-acrylonitrile (ASA) contains 30 percent by weight glass fibers and a halogen-based flame retardance package. “The particular advantages of the material are its extremely low warpage and shrinkage, combined with its high flame retardance. We see great potential for application in precision components for vehicle battery systems,” says Marc Marbach, head of Sales Segments E&E in the LANXESS High Performance Materials (HPM) business unit. It took just two-and-a-half years to go from the initial idea to extensive testing and finally to use in full-scale production.
To be more energy efficient, many people have replaced their incandescent lights with light-emitting diode (LED) bulbs. However, those currently on the market emit a lot of blue light, which has been linked to eye troubles and sleep disturbances. Now, researchers reporting in ACS Applied Materials & Interfaces have developed a prototype LED that reduces — instead of masks — the blue component, while also making colors appear just as they do in natural sunlight.

Chocolate is a beloved treat, but sometimes the cocoa beans that go into bars and other sweets have unpleasant flavors or scents, making the final products taste bad. Surprisingly, only a few compounds associated with these stinky odors are known. Now, researchers reporting in ACS’ Journal of Agricultural and Food Chemistry have identified the two compounds that cause musty, moldy scents in cocoa — work that can help chocolatiers ensure the quality of their products.

Cologne, April 29, 2021 – Ultra-high-performance concretes (UHPCs) are reckoned to be the construction material of the future. When they are colored, however, you have to ensure that the prescribed compressive strength of more than 150 megapascals is still achieved. The iron oxide pigments from LANXESS’s Bayferrox brand are perfect for UHPCs, as has been verified by the association of German cement manufacturers (VDZ) based on an analysis of compressive strength conducted to DIN EN 12390-3.
