Product description:
This instrument is suitable for the determination of soft polyurethane foam falling ball type can rebound resilience. The instrument by a given diameter and quality of steel ball in the specified height on free falling on the foam sample, calculate the springback of maximum height of steel ball and ball drop height ratio is the percentage of spring rate, expressed as a resilient rate of foam plastics can rebound resilience.This machine adopts microprocessor to control, liquid crystal Chinese display, and can print test data.This machine has the characteristics of safety, reliability and high measuring accuracy.
