The sponge ball rebound tester is suitable for the determination of soft polyurethane foam falling ball type can rebound resilience. This machine adopts microprocessor to control, LCD display, and can print test data. The machine is characterized by safety, reliability and high measuring accuracy. This instrument through a given diameter and the quality of steel ball in the specified height on free falling on the foam sample, calculate the spring back of maximum height of steel ball and ball drop height ratio is the percentage of spring rate, expressed as a resilient rate of foam plastics can rebound resilience.
