Polymeric Materials Ball Rebound Coefficient Test Machine Foam Rebound Resilience Test Machine

Description -spongy ball springback tester

1, the machine design and manufacture according to GB/T6670-2008, ASTM D3574 American standard and ISO8307 test standard. At the same time, Japanese car seat cushion with urethane foam SES N3296 test method. Is suitable for the determination of soft polyurethane foam falling ball type can rebound resilience. 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 springback 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.This machine has the characteristics of safety, reliability and high precision.
