ISO8307 ASTM D3574 Foam Drop Ball Rebound Tester Foam Coefficient Test Machine
It is a professional sponge, foam, rubber and other soft materials and design of a cost-effective instrument. The ball is mainly free falling on the soft foam or other elastic material sample. Measuring the rebound height of the instrument, mainly used to determine the resilience of polyurethane elastic material test items (rebound coefficient).

APPLICATIONS& TEST PURPOSE
It is designed according to ISO 8307 an d ASTM D 3574 test standards . It through specify diameter and mass ball fall on the foam specimen fro m certain height, calculate the percentage between m aximum drop height and rebound height, indicate fo am resilience by spring rate. It uses PLC control, LCD display and with USB port to output test results.
