Foam Rebound Resilience Tester

The Foam Rebound Resilience Tester is a laboratory instrument designed to evaluate the elastic recovery performance of soft and flexible materials, including polyurethane foam, sponge, rubber, and similar materials. The tester measures the rebound height of a steel ball after free fall onto the specimen surface and calculates the rebound resilience value. This test provides important data for evaluating cushioning performance, comfort, and material durability in various applications.

FAQ

(1) What does a Foam Rebound Resilience Tester measure?

The tester measures the rebound resilience of flexible materials by recording the rebound height of a steel ball after impact. The result is used to evaluate material elasticity, energy recovery, and cushioning performance.

(2) Which materials can be tested with this instrument?

It is mainly used for flexible cellular materials such as polyurethane foam, sponge, and similar elastic materials. It is commonly applied to foam products used in furniture, automotive, packaging, and footwear industries.

(3) Why is rebound resilience testing important for foam materials?

Rebound resilience indicates how effectively a material can recover after compression or impact. The test helps manufacturers compare material performance and ensure products meet expected comfort and durability requirements.

(4) Which standards are used for foam rebound testing?

The tester is commonly used according to GB/T 6670-2008 for flexible cellular materials. Some applications may also refer to ASTM D3574 depending on the material type and customer requirements.

(5) How to choose the right model for foam testing?

Selection depends on the tested material, required standards, accuracy requirements, and laboratory conditions. QINSUN engineers can recommend a suitable solution based on your testing needs. Contact us for professional support.
