Foam Roller Shear Test Machine
Foam Roller Shear Test Machine
Products description:
Foam Roller Shear Test Machine is used to determine the resistance to compression fatigue of flexible cellular polyurethane using dynamic roller compression test. The Roller Shear Machine fatigues a specimen dynamically with a constant force deflecting the material both vertically and laterally. It has been used for many years in the foam industry to determine the percentage loss in thickness.
