The sponge rebound coefficient tester is designed and manufactured in accordance with GB/T6670-2008, and conforms to ASTM D3574 and ISO8307 test standards. It also conforms to the test method of Japanese car seat cushion with ammonia and ethyl formate foam SESN3296; it is used to measure sponge, foam, Instruments designed for soft materials such as rubber. Mainly drop the steel ball freely on the flexible foam plastic or other elastic material sample. The instrument for measuring its rebound height is mainly used to measure the rebound performance (rebound coefficient) observer in the polyurethane single-sex material test project.
