Bayer at Plastics in Motion: Showcased Low-gloss PC Blend for Auto Interiors

Published on 2015-06-16. Author : SpecialChem

PITTSBURGH -- Personalization is a significant trend in consumer design as people seek individualized experiences from the telephones in their pockets to the vehicles they drive. Automotive interior designers must feature improved functionality and an elegant, luxurious appearance.

To appeal to consumers, automotive OEMs are seeking low-gloss, durable materials that eliminate painting during manufacturing yet maintain pleasing aesthetics for many years. Automotive OEMs and Tier suppliers are also seeking streamlined component fabrication processes to achieve improved productivity and cost efficiencies.

As among the leading raw materials suppliers to the automotive industry Bayer MaterialScience LLC is developing new polycarbonate (PC) materials and processes to meet these challenges. Bayer experts shared recent advancements during the Plastics in Motion Automotive Plastics Conference and Exhibit (June 1-4) in Dearborn, Michigan.

Dr. Marina A. Rogunova, principal scientist, Bayer MaterialScience, presented inherently low-gloss Bayblend Polycarbonate (PC) for automotive interior applications during the Plastics in Automotive Interiors, Exteriors and Engine Compartment session. Rogunova shared details on the development and properties of a low-gloss polycarbonate (PC) blend that is an easy-to-process alternative to polypropylene (PP). The material grade, Bayblend® LGX 300 resin, is a polycarbonate (PC) blend with inherently low gloss and high flow that allows it to accurately replicate different types of surface finishes and achieve gloss levels significantly lower than the materials targeted for displacing PP by automotive OEMs.

Jessee McCanna, principal engineer, Bayer MaterialScience LLC, presented Direct Coating / Direct Skinning (DCDS) technology as part of the Innovations in Manufacturing and Assembly session. He explained how DCDS combines standard injection molding with reaction injection molding in a single mold, utilizing a polycarbonate-based substrate with a polyurethane coating or aliphatic (or aromatic) self-skinning foam. The integration of the two processes can reduce the overall part cost, compared with current manufacturing methods, while increasing quality, performance, design freedom, and product differentiation.
