CATEGORY WINNER: HALL OF FAME AWARD
The first Mold In Color (MIC) weatherable grille, used on the 1987 Volkswagen Golf, has been named the 2022 Hall of Fame Winner. The industry's first MIC weatherable grille, made possible with Luran S® ASA from INEOS STYROLUTION (pre-colored plastic resins used in the plastic injection-molding process so the molded part emerges in a specific color and finish), proved to be a game changer for vehicle front grilles by providing a weatherable, paint-free exterior surface. To be considered for a Hall of Fame Award, an automotive plastic or composite component must have been in continuous service in some form for at least 15 years and broadly adopted in the automotive industry. This application certainly qualifies, as MIC grilles have become the industry standard used by every major OEM for front grilles, replacing traditionally painted materials on over 300 million exterior parts including grilles, mirrors, pillars, spoilers, fog bezels, and more.
Further technology now being developed around MIC ASA includes radar detection covers, lidar equipment, and CHMSL (Center High-Mounted Stop Lamp) bezels. The automotive market for MIC ASA has now grown to over 100 million lb globally.
The companies involved in developing the first MIC weatherable grille application include: OEM - Volkswagen Group; Molder/Processor - Volkswagen Group; and Material Supplier - INEOS STYROLUTION. Representatives from these companies accepted the SPE Automotive Hall of Fame Award on behalf of the original team that worked to develop the technology.
