Machine Introduction

This machine is designed and manufactured according to ASTM D3574. ISO 8307. GB/T6670-97. It is suitable for determining the falling ball resilience of soft polyurethane foams. The instrument calculates the maximum rebound height of the steel ball and the percentage of the falling height of the steel ball by the steel ball with a given diameter and quality falling freely on the foam sample at a specified height, and the rebound rate represents the resilience of the foam. The machine uses microprocessor to control, touch screen Chinese display, and can print test data. The machine has the characteristics of safety, reliability and high measurement accuracy.
