Bayer MaterialScience has announced the availability of a polycarbonate and polyethylene terephthalate (PC+PET) mix for manufacturing horizontal body parts for use in automobiles by recycling the utilized industrial and consumer products.
According to Dr. Eckhard Wenz, who works at Bayer MaterialScience as a technical product service specialist for polycarbonate and its blends, the patented product Makroblend GR 235M offers a strong raw material basis when compared to any other conventional material. He explained that the property profile of Makroblend GR 235M can be equated with that of Makroblend UT 235M.
The Makroblend UT 235M is a virgin material used to fulfill the most rigorous needs of the automobile industry. The Makroblend GR 235M is designed to be compatible with a number of bodywork parts such as trunk skirts and lids, spoilers, covers for convertible top compartment lids and antennas.
Bayer MaterialScience makes use of high-purity PET from beverage bottles to manufacture material that meets the statutory requirements of the food industry. The company produces a polycarbonate for manufacturing water bottles of five gallon capacity. The raw material mix can be used as an alternative for sheet mold components (SMC), aluminum and sheet steel used in bodywork parts.
In large production units, the use of high-tech material blend is found to be significantly economical because the manufactured molded parts do not require any reworking and can be straight away painted without the need for any pretreatment. This feature helps in the manufacture of products with Class A type of surfaces. More over, the product mix offers a lower level of density thus weighing less. The design flexibility of the material mix when compared to the use of metal provides possibilities to cut down the cost of production through the integration of functions.
The other advantages of the new product include its low level isotropic thermal linear expansion property, its capability to realize seamless gap between two nearby assemblies, durability and high-level of resistance to heat. The low level isotropic thermal linear expansion property can be effectively utilized in the making of large-sized components with low level internal stress thus showing negligible level of aberration.
