Suzuki develops light polypropylene resin material which excels in material coloring for automobiles
Suzuki has developed polypropylene (PP) resin material which is approximately 10% lighter than the current PP and excellent in material coloring, called the Suzuki Super Polypropylene (SSPP), and has adopted them on the front bumper under garnish of the Escudo which was launched in Japan on 11 July, 2012. The front bumper under garnish equipped to the Escudo has adopted SSPP on market models for the first time in the world. It realizes high brightness silver metallic color without painting due to the high colorability of SSPP. Because it has no paint layer, in case of scratches such as stone chips, it is difficult to distinguish a scratch. It can also reduce environmental load because it does not emit volatile organic compounds (VOCs).
In the recent years, the need for weight reduction of automobile’s resin part is increasing, and there is a high demand for reduction of environmental load substance. For these reasons, material coloring of parts is carried forward, in which the colored resin, pre-mixed with colorant and bright coloring before molding, is used without painting. SSPP is a new technology in which a patent has been applied for, and Suzuki will expand the usage of SSPP to the interior parts and exterior parts such as bumpers in the future.
