Covestro Exhibits at the Battery Show in Stuttgart

Covestro, a global provider of chemical solutions for the plastics industry, exhibits its vast product portfolio at the Battery Show in Stuttgart from May 7-9, 2019.

At booth number 369 at the Battery Show, the company will present its current developments with thermoplastics, but also battery components that provide good impact protection and are efficiently manufactured from polyurethane using the pultrusion process.

Covestro has many years of experience with covering lithium-ion batteries for laptops and other electronic devices and has developed various polycarbonate blends for this purpose. Due to their favorable property profile, the materials are also well suited for manufacturing modules, housing parts, cell holders and crash absorbers for electric car batteries. They are lightweight yet robust and dimensionally stable and, depending on requirements, they also come equipped with a flame retardant.

"A current focus of our activities is the development of processes for the efficient mass production of complex plastic parts for batteries," explains Dr. Julian Marschweski, expert for electromobility at Covestro. "In order to accommodate as many cells as possible in the battery’s interior, our flame-retardant polycarbonate blends must be processed into especially thin-walled parts."

A current cooperation between Covestro and the adhesive manufacturer Henkel involves permanently bonding plastic parts in high-voltage batteries with the help of UV-activated Loctite® adhesives. Together the partners are testing this on injection-molded parts made of the flame-retardant PC+ABS blend Bayblend® FR3040 EV. At a thickness of only one millimeter, the plastic already meets’ category V-0 of the Underwriters Laboratories’ UL94 flammability rating but shows good permeability for UV radiation in the wavelength range above 380 nanometers.
