Why is compression force deflection important?

Durometer vs Compression Force Deflection (Psi)

 

two tires one with a psi of 10, the other with 35.

Our focus is on “Performance”! Compression Force Deflection, measured in pounds per square inch (PSI), is the accurate test method to measure material firmness at varying compressive levels — a true representation of performance as an ejector in an application.

Durometer is the measure of the hardness of a material’s surface. Since it only measures a small point of the material surface with limited penetration, the test method is less accurate in determining ejector performance.
