  • Excellent flame retardant properties: Good flame retardant performance with a lighter and thinner wall design, with a combination of excellent FR grades
  • High flow and good impact resistance: High flow for large-sized parts and thin-wall design, good mechanical properties, which is reflected in its excellent impact resistance.
  • High design freedom and excellent colorability: Maximum design freedom for consumer electronics designers, while achieving excellent appearance and functionality.

Consumer electronics market trends 

Today’s consumers are after slimmer, sleeker personal electronics, ranging from flexible smartphones to lighter and thinner TV screens. With their increasingly powerful performance, electronics are also integrating more functions to become more sophisticated and delicate. As such, manufacturers are tasked with ensuring uncompromising product safety and reliability, while also achieving a lighter, thinner, and more complex structural design that upholds modern aesthetics. This has put higher requirements on the materials in use, including but not limited to lightweight, impact strength, processability, and flame-retardant properties. 
However, in the typical production of a thin-wall enclosure or structure, manufacturers often encounter problems such as cracks and surface defects.
To address this challenge, Covestro has launched a portfolio  of thin-wall, flame-retardant products that combine excellent processability and outstanding impact resistance, answering to the trends of thin-wall electronic designs.

Our advanced thin-wall flame-retardant solutions help customers achieve lightweight and simple thin-wall designs, while reducing their carbon footprint to achieve carbon neutrality. Thin-wall FR materials of Covestro also offer excellent functionality, allowing for flexible design freedom and more diverse applications in consumer electronics.
