APPLICATION BULLETIN Replace complicated in-house panel fabrication with ready-to-install engineered composites. PolyOne’s industry-leading portfolio of engineered composite panels offers a solution to these challenges. PolyOne engineered composite panels can be tailored to your design and performance specifications.

Those who also want a low-maintenance space often select vinyl or wood-plastic composites. These new materials are available in a range of gloss levels and use temperatures, and can be used to produce capstock for vinyl, cellular vinyl, or wood-plastic composite profiles, or solid profiles and sheet if needed. PolyOne’s extensive experience in exterior applications combined with Geon Bold weathering data from multiple geographic regions provides customers with the necessary support and confidence during the selection process.

The benefits of using long fiber thermoplastic (LFT) composites in these automotive applications to achieve these objectives are well documented. Furthermore, LFT composites are injection-moldable, providing a highly repeatable process that increases production efficiency and reduces scrap. Our long fiber composites offer an excellent opportunity for automotive aftermarket designers to enhance their components’ performance, aesthetics, and sustainability.
