Covestro’s special surface technology enables creative and modern interior designs

Decorate your home with premier materials

With the continuing evolution of design concepts, consumers are paying more attention to interior design. Not only should a room be designed to be functional, but it should also maintain beautiful aesthetics. BULL’s new design of the decorative switch & socket has increased its value to consumers and created more space for interior design innovation.
Covestro’s special surface technology enables creative and modern interior designs

BULL’s decorative switch & sockets employ Covestro’s injection molding and surface technologies. The new design enhances the switch with style, function integration, and higher safety solutions for the future home.


BULL, seeking help from Covestro, plans to develop a series of decorative switch & sockets that provide higher safety solutions and follow modern design trends.


The decorative switch & socket needs to improve safety solutions while applying a variety of surface materials that maintain a trendy design. The products should be flame-retardant while having high-voltage, high-current, and ultra-high temperature protection, without compromising aesthetic appeal. BULL is seeking lightweight and sturdy materials that have high safety standards and design flexibility.


BULL’s new switch & socket applies Covestro’s Makrolon® polycarbonate made by combining injection molding with special surface technology. Makrolon® polycarbonate is robust, lightweight, durable, and flame-retardant with excellent heat resistance. Special colors can also be developed upon request. These material families provide perfect solutions for switch & sockets, and not only meet industrial standards (IEC), but also are abreast of future trends and design concepts. Importantly, Makrolon® polycarbonate meets BULL’s needs for materials with high safety (UL94 V0) and environmental (Non-Br, Non-Cl) standards.
