Polypropylene and thermoplastic polyolefin (TPO), widely used in the automotive industry, require stabilization systems to retain mechanical properties and aesthetics during processing and end-use applications. Several other important attributes can be affected by the choice of stabilization systems. This webinar compares the performance of various stabilizers in meeting weathering requirements and in other attributes important to interior and exterior applications. Because of the effects on other attributes, stabilizers have different values for interior and exterior applications, which are also discussed.
