Recycling rubber is gaining traction globally in efforts toward a circular economy. Beside sustainability, it also is recognized as a cost-efficient raw material in applications such as modified asphalt, virgin rubber blends and molded goods from ground tire rubber.
However, its applicability is limited by performance gaps or processing challenges whenever it is compared to virgin rubber products or polymer materials.The application of trans-polyoctenamer (TOR) has proved to be a valuable tool in overcoming these gaps.
We will review the literature and show the latest mechanistic insights on trans-polyoctenamer’s mode of action. The surface coating effect of TOR provides an effective method that turns recycling rubber into a valuable resource by improving performance and processing of rubberized asphalt, rubber blends and molded goods.
