Consumer Electronics Biobased PA 6.10 for robot vacuum cleaner Renewably sourced polyamide brings style, durability, and performance to households Today’s families focus on quality of life, purchasing appliances such as robot vacuums that are efficient, durable, and operate quietly. According to Celanese Engineered Materials (Dallas, TX, USA), these small home appliances went from expensive novelty (costing up to USD 1,800 in 2001) to mainstream appliances in just a few years. Today, analysts estimate that 20 % of all vacuum cleaners sold worldwide are robotic. Recently, a global leader in the design and manufacturing of robot vacuum cleaners approached the Celanese Engineered Materials team seeking more sustainable, higher-performing materials for its newest robot vacuum. Celanese engineers collaborated with the OEM to identify manufacturing and aesthetic challenges; then the team customized a solution that combined performance with style and sustainability. Before creating the custom material, the engineers considered that materials for robot vacuums must be: • Durable and protective: Robot vacuums must have a durable housing that’s able to bounce off chair legs and other hard objects while protecting precision sensors inside the appliance. • Stylish and quiet: Consumers want a stylish look because robot vacuums spend most of their useful lives perched in a docking station waiting for their next mission – and visible to all. Additionally, noise must be kept to a minimum to help preserve a peaceful home environment. • Lightweight: Reducing the weight of robot vacuums increases their range and makes it easier for consumers to carry them from room to room or between floors of a home. • Sustainable: Materials selected for the robot vacuum need to help the manufacturer achieve its sustainable development goals. To fulfil the manufacturer’s sustainability goals, the Celanese team selected Zytel ® RS polyamide customized to meet the manufacturer’s high standards for the robot vacuum’s LIDAR-based laser distance sensor cover. Zytel RS resins typically contain between 20 % and 100 % renewably sourced biomass (by weight) derived from castor beans. In this case, the PA 6.10 grade contained up to 65 % renewably sourced biomass content. The customized material provided an optimized balance of high stiffness and suitable strength, while the dimensional stability of the polymer contributed to the laser sensor’s precision and sensitivity. And the vivid white colour of the Zytel RS compound provided the sophisticated aesthetic finish product designers sought. Celanese also provided Computer Aided Engineering (CAE) support that helped reduce the time from the initial concept to commercial introduction of this new appliance. Note: Celanese acquired DuPont Mobility & Materials division, which includes Zytel RS, on November 1, 2022. For additional information, please visit the website.
