How Plastics Improve Vehicle Appearance, Weight And Performance
As electric and hybrid vehicles become more common, and carmakers compete to attract buyers
with better systems and designs, automakers are looking for materials suppliers with technical and
applications expertise. Celanese Corp. (Irving, TX) says that it has precisely those resources to help
automotive OEMs create attractive, lightweight and better-designed vehicles.“Automakers answer to
government regulators, investors and drivers around the world, who collectively never stop improving
design, safety and performance, all while keeping costs down,” said Todd Elliott, Vice President of
Material Solutions at Celanese. “As a result, many interior, exterior and under-hood components in
cars and trucks are now made with plastic rather than metal, which helps fulfill regulatory and financial
requirements while giving automakers the freedom to design for the future.”

Automotive OEMs, suppliers and molders worldwide use Celanese polymers as effective and less-expensive metal replacements for interior and exterior parts. Injection molded components
typically allow designers and engineers the freedom to create high performing, visually appealing
vehicles while reducing manufacturing steps, said the company.While lightweighting is an important factor, it’s appearance that first captures consumer imaginations. MetaLX molded-in color polymers with a metal effect allow designers and engineers the freedom to replace metal and
improve both interior and exterior components while eliminating the need to perform secondary
painting or plating operations. MetaLX polymers create high-gloss or matte finishes that are UV
and scratch resistant and light in weight without sacrificing dimensional stability or mechanical
properties, according to the company.Polymer seating components, overhead bins and consoles are
easier to mold into precise shapes and are stronger and less expensive to produce, while thermally
conductive plastics in LED headlamps are lightweight and safer and allow for efficient, high-output lighting, said Celanese.Celanese engineers apply their experience to help auto OEM
designers and engineers think about how to design critical, multi-part, complex systems with
chemical-resistant, dimensionally stable and lightweight materials. Many materials enable smaller
engines to lower fuel consumption and emission levels, while other polymers facilitate higher
flow,complex part manufacturing. As automakers address complex, thick-wall part systems, Celanese
recently launched at K 2016 an innovative polymer, Celstran high flow LFT, high mechanical
profile, long-fiber thermoplastics that meet component design specifications.“Drivers expect
dazzling designs and superior performance at practical prices without compromising safety,
durability or functionality. Manufacturers must meet these demands while also staying true to
their goals,” said Elliott. “We’re our customers’ first choice for engineered materials
because we fulfill their immediate needs but also inspire them to revolutionize how they design
vehicles to stay ahead of regulations and driver demand and get better vehicles to market
first.”
