Application of recycled rubber powder (RRP) in NR / SBR compounds

摘要

This study presents tire recycling process to produce rubber powder (particle size, 0.1-1.00 mm), and explores use of recycled rubber powder in NR / SBR compounds as substitution for black fillers (soot). A number of tests and measurements of rubber compound properties were used to find the best ratio of soot and rubber powder. Guidelines to what percentage of recycled rubber powder should be added in a compound without affecting mechanical properties of finished rubber products are also provided.
