WESTCO™ Carbon Black Highly Reinforcing – Tire Grades CAS# 1333-86-4
These WESTCO™ Carbon blacks are fine particle size, highly reinforcing carbon blacks used most commonly in tire applications. Medium sized, semi-reinforcing grades for use in a variety of rubber compounds. They offer improved tensile strength and modulus as well as increased abrasion resistance in tires and other rubber products. The less reinforcing grades enhance the extrudability and mold flow of compounds while the highly reinforcing grades are recommended for compression molding applications.
