How Is Raw Rubber Evaluated for Rail Transit Vibration Damping and Building Seismic Isolation?
Quick AnswerRaw rubber is only one component of vibration damping or seismic isolation devices; material changes must go through compounding, vulcanization, finished product performance validation, and customer approval processes.
Evaluation Hierarchy
Proceeding from raw rubber batch consistency through the compounding process, then evaluating finished product stiffness, damping, fatigue, aging, adhesion, and other properties. Specific parameters are determined by customer product specifications.
Procurement Reality
Identify the finished device manufacturers, external compounding centers, and actual raw rubber purchasers. Natural rubber procurement volume cannot be directly extrapolated from project quantities.
