Description:This new ASTM publication is a practical guide that explains the important chemical and physical properties to be used in making judgments on the quality of raw materials or compounding ingredients, and their usability in the production plant. It provides a basic description of the test methods and characterizes each group of raw materials. But more importantly, it compares and contrasts the advantages and disadvantages of selecting various test methods. Chapters cover: • ASTM D11 and D24 Standards; Importance of Quality • General Test Methods • Testing Natural Rubber • Testing Synthetic Rubber • Testing Carbon Black • Testing Silica and Organosilanes • Testing Mineral Fillers for Use in Rubber • Oils, Plasticizers and Other Rubber Chemicals • Testing Recycled Rubber • Standard Test Methods—Insuring High Quality Output • Comparison of Test Repeatability and Reproducibility for Rubber Test Methods
