Non-toxic and heavy-metal-free ingredients and biodegradable carrier resins. Avient has developed sustainable technologies that offer lightweight alternatives to heavier metals, while delivering comparable or improved performance. OnColor™ FX™ Special Effect Colorants achieve an appearance comparable to glossy or brushed metal while reducing VOC emissions by replacing paint.

In the transportation industry, plastic has proven to be durable, lightweight and corrosion resistant while offering fuel savings, design flexibility and high performance, often replacing traditional materials such as metal and glass. Polymer formulations and structures have advantages over metals, wood, rubber, glass and other traditional materials, which have resulted in the replacement of these materials across a wide spectrum of applications. Examples of how our strategy supports these trends can be found in numerous initiatives: active participation in the medical device market, leveraging our global footprint to deliver consistent solutions globally, light weighting and metal replacement and development of solutions that respond to ever-changing market needs by offering alternatives to traditional materials.

Light-weighting solutions that replace heavier traditional materials like metal, glass and wood, which can improve fuel efficiency in all modes of transportation
