Frequently Asked Questions

ASTM D3575 is used to evaluate the physical and mechanical properties of flexible cellular materials made from olefin polymers. It ensures materials meet performance requirements for cushioning, durability, and insulation, supporting consistent quality and reliable product performance across applications.

Density affects strength, cushioning ability, and durability. Higher density foams generally offer better load-bearing capacity and longevity, while lower density foams provide lighter weight and improved flexibility for specific applications.

Compression testing measures how foam behaves under load, including deformation and recovery. It helps determine the material’s ability to maintain shape and performance under repeated or sustained pressure.

Factors include sample preparation, environmental conditions, foam structure, and testing parameters. Proper control ensures accurate and repeatable results.

Tensile strength indicates the foam’s ability to resist stretching forces. It is important for applications where the material may be subjected to tension or deformation.
