Trendwatch™ Overcoming 5G Component Challenges (English) Key factors and comparisons to consider when replacing aluminum with long-fiber-reinforced thermoplastic (LFT); including processing and material performance summaries

We create specialized and sustainable material solutions that transform customer challenges into opportunities, bringing new products to life for a better world. Our customers value the breadth of our solutions as we can tap into a broad array of raw materials to solve their specific needs. Our formulation expertise supports material science decisions, while our processing expertise guides customers to use the materials properly.

Examples include: • Unique technologies that improve the recyclability of products and enable recycled content to be incorporated, thus advancing a more circular economy • Light-weighting solutions that replace heavier traditional materials like metal, glass and wood, which can improve fuel efficiency in all modes of transportation and reduce carbon footprint • Sustainable infrastructure solutions that increase energy efficiency, renewable energy, natural resource conservation and fiber optic / 5G network accessibility Avient employs approximately 8,800 associates and is certified ACC Responsible Care® and a founding member of the Alliance to End Plastic Waste. Our formulation expertise supports material science decisions, while our processing expertise guides customers to use the materials properly.
