Bayer offers new “green” high-tech material blend of PC+PET


Bayer MaterialScience’s new material blend conserves resources and performs as well as virgin material. It is an advantageous substitute for sheet steel, aluminum and sheet mold compounds for horizontal automobile bodywork parts, the company informed. The development of the high-tech structural material is a response to the trend toward recyclates in automaking.


MANNHEIM, GERMANY: Bayer MaterialScience is offering a new “green” high-tech material blend of polycarbonate and polyethylene terephthalate (PC+PET) for horizontal automobile bodywork parts. The premium material is manufactured from the highest quality post-consumer and post-industrial recyclates.


“Thanks to its excellent raw material basis, Makroblend GR 235M needs not fear comparison with virgin material at all,” said Dr Eckhard Wenz, Technical Product Service Specialist for Polycarbonate and its blends, Bayer MaterialScience.


The property profile is comparable to Makroblend UT 235M, an established material for the production of bodywork parts. Possible applications are bodywork parts such as spoilers, trunk lids and skirts as well as covers for antennas and convertible top compartments.


The PET for the new material comes from beverage bottles. These are produced from high-purity PET grades that satisfy the strict statutory specifications of the food industry. The new material blend is particularly well suited as a substitute for sheet mold compounds (SMC), sheet steel and aluminum in bodywork applications. With large production runs, it is significantly more economical because it yields moulded parts that require no re-working and can be coated without pre-treatment to produce Class A surfaces. Its primary advantages over metals lie in greater design flexibility and potential for reducing costs through functional integration.
