Recommendations For Selecting And Using Industrial Sponges

Selection by Density: Low density (<30 kg/m³) is suitable for liquid absorption, while high density (>80 kg/m³) is suitable for load-bearing applications.

Safety Certification: Materials intended for food contact must comply with FDA 21 CFR 177.2600, while sponges used in construction must pass the UL94 flammability test.

Density: 15–200 kg/m³; higher density corresponds to greater load-bearing capacity.

Resilience: 30%–95%; a rate of >75% is recommended for applications involving frequent compression.

Compression Set: ≤5%–20%; a lower value indicates superior durability.

The applications of industrial sponges continue to expand alongside breakthroughs in materials science; in the future, even more disruptive applications may emerge in fields such as carbon neutrality and smart wearables.
