Trailblazing applications enabled by specialized Celanese Engineered Materials polymers that will be on display in the Celanese Innovation Showroom ranged from e-bikes, wireless electric vehicle (EV) chargers, and hybrid EV battery cooling plates to LIDAR-based smart vacuums.

In the advanced mobility category, Celanese materials excel at reducing weight without compromising performance. Specific material performance requirements by application are as follows:

 ▪  E-bikes consist of multiple components, from structural elements and saddles to e-motors and gears. Materials serving these needs include Hytrel TPC-ET for flex fatigue, wear, and abrasion resistance; Zytel nylons for metal replacement, structural support, and high-temperature resistance; Zytel HTN PPA for structural support, ultra-high-temperature resistance, stiffness, and dimensional stability; Zytel LCPA (flexible) for thermal, chemical, and hydrolysis resistance; Crastin PBT for superior flow, halogen-free flame retardancy, hydrolysis resistance, electrical properties, and processability; and Rynite PET for dimensional stability and durability.

 ▪  ADAS brackets present demanding requirements for impact resistance, especially when they hold safety sensors and cameras that increase pedestrian safety. Celanese developed a laser-markable Zytel nylon material that meets performance targets, reduces assembly time and reduces cost for global automotive component manufacturer Nifco. The result – a lighter and pre-aimed bracket – will be on display at CES.

 ▪  EV batteries face three key challenges – energy density, which affects range; manufacturing complexity, which affects production cost; and thermal management, which is required for performance and safety. Celanese developed a hybrid cooling plate that improves thermal management. In addition, the company has introduced a novel 3-in-1 battery concept that increases energy density by consolidating functional parts into a modular system. Together with customer VMAX New Energy, Celanese is also helping to bring wireless EV charging technology to the market. Solutions include Zytel nylons, Zytel HTN PPA, and a new chemical bonding technology for joining aluminum and polyamide.

 ▪  EV motor mounts can create a quieter interior experience by isolating and damping high-frequency motor noise, which becomes more prominent with quieter EVs. Zytel NVH, a structural material that can be tuned to reduce specific frequencies, received recognition from Automotive News as a PACE award finalist in Cadillac Lyriq motor mounts. It noticeably lowers noise levels and increases passenger comfort.

New products in the consumer electronics segment need a mixture of electrical compatibility, aesthetics, and resistance - to heat, assembly methods, and impact. At CES 2023, Celanese will demonstrate successful products featuring the following material solutions:

 ▪  Polymeric heat sinks are a workhorse in consumer electronics that need to stay cool while being lightweight. Next generation CoolPoly TCP E3629 (thermally conductive polymers) provide as much as 200 times the thermal conductivity of conventional plastics, while also improving UV resistance, impact strength, and toughness. They also provide a 40% weight savings versus aluminum.

 ▪  Robotic vacuum cleaners need not only a stylish appearance but also LIDAR-transparent materials that can support smart-sensor designs. A global robot vacuum manufacturer chose Zytel RS, a renewably sourced nylon with 65% biomass, for the LIDAR cover on its smart vacuum. The material features a vivid white color with superior mechanical performance and dimensional stability.
