It is a cost-effective instrument designed for professional testing of soft materials such as sponge, foam, rubber, etc. This machine is designed and manufactured according to GB/T6670-2008, and complies with ASTM D3574 and ISO8307 test standards. It also complies with the amino acid used in Japanese car seat cushions Test method for ethyl formate foam SES N3296. Applicable to the determination of the falling ball resilience of flexible polyurethane foams. This instrument calculates The percentage of the ratio of the maximum height of the steel ball rebound to the height of the steel ball falling is the rebound rate, and the rebound rate represents the rebound performance of the foam. The machine is controlled by a microprocessor, displayed in liquid crystal in Chinese, and can print test data. The machine has the characteristics of safe, reliable and high measurement accuracy.
