Tall Oil Pitch (TOP) is the heavier, resinous fraction that remains after the extraction of fatty acids from tall oil—a byproduct of the Kraft pulping process. This viscous, dark-colored material is prized for its robust adhesion properties and high molecular weight. TOP is commonly utilized as a binder and modifier in asphalt, sealants, rubber formulations, and other industrial applications where durability and resistance are paramount. As a renewable, pine-derived byproduct, TOP offers a sustainable alternative to petroleum-based resins, supporting both performance and environmental goals.
