Foam Rebound Resilience Tester
The Foam Rebound Resilience Tester is a laboratory testing instrument designed to evaluate the elastic recovery performance of soft materials such as polyurethane foam, sponge, rubber, and similar flexible materials. It determines the rebound characteristics by measuring the rebound height of a steel ball after free fall onto a specimen surface, providing a quantitative rebound resilience value.
This parameter is essential for assessing cushioning performance, comfort level, and durability of foam-based materials.
Applications
The instrument is widely used in material testing and product quality control across multiple industries:
(1) Furniture manufacturing — evaluation of sofa cushions, mattresses, and seating foam
(2) Automotive industry — testing of seat foam, interior cushioning materials, and vibration damping components
(3) Packaging industry — assessment of protective foam materials
(4) Footwear industry — evaluation of midsole and insole foam performance
(5) Material research laboratories — development and comparison of elastic polymer materials
(6) Quality inspection institutions — standardized foam performance testing
