Classify the Source of Recycled Rubber Classification The source of rubber and particle size distribution are important factors in rubber compounding and identifying the appropriate rubber feedstrock for a product. Recycled rubber is used as a feedstock for many products and uses including molded rubber products, devulcanization, recovered carbon black, tire-derived aggregate, rubber asphalt, turf infill, thermal decomposition and other tire and non-tire derived products and end uses. Classification of recycled vulcanizate particulate rubber is based source of rubber on the in ASTM D5603-19 (Table1) and the particle size distribution (Table 2). Table 1 Table 1 captures eight classifications by the source of rubber. Identifying the source of the feedstock may add to the success in the development of products and technologies. Tire-derived material (TDM) and non-TDM feedstock are derived from a variety of processes using an array of equipment that can handle the tire and non-tire rubber. The classification of the source of rubber includes: Classification 1: Whole Tires Certain types Classification 2: of whole tires with further classification Classification 3: Non-highway tires Classification 4: Tread only from all highway tires Classification 5:Tread only from non-highway tires Classification 6:Tread and shoulder rubber from the retread process to produce buffings Classification 7:Tread, shoulder and sidewall rubber from the retread process to produce buffings Classification 8:Non-tire rubber Recycled rubber particulate is important in rubber compounding so that the results when the rubber has been processed by some means will obtain a desired particle size distribution. Recycled on the source of rubber in ASTM D5603-19 Table1)and the particle size distribution Table 2). Table 1 captures eight classifications as the source of rubber. from a variety of processes using an array of equipment that may that can handle the tire and non-tire rubber. The classification of the source of rubber includes: Classification 2: Certain types of whole tires with further Classification 4: Passenger car, light truck, truck and bus tires Classification 6: Tread and should from highway tires Classification 7: Tread, shoulder and sidewall from highway tires Classification 8: Non-tire rubber
