Milling to soften raw rubber and mix dry ingredients into the compound

1. Rubber is a material that shares some of the properties of both solid and liquid. In this video, tough raw natural rubber has been loaded into a mill, where counter-rotating steel rollers grind it into a softened, semi-fluid mass. This action, in the presence of oxygen in the air, tears the long, chain-like rubber molecules into shorter lengths. The rubber becomes softer and easier to process, and it readily accepts any other ingredients that may be needed to create a "compound". A compound is the total combination of the rubber polymer and modifiers, such as reinforcing fillers, oils, pigments, antioxidants, vulcanization chemicals, etc.
