Product Description

The main function:
This machine 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 SES N3296 for urethane foam for Japanese automobile seat cushions. It is suitable for measuring the falling ball type of flexible polyurethane foam. Rebound performance. The instrument uses a steel ball with a given diameter and mass to freely fall on the foam sample at a specified height, and calculates the percentage of the ratio of the maximum height of the steel ball to the falling height of the steel ball, that is, the rebound rate. Rebound rate indicates the resilience performance of foam.
