Slow-rebound foam openers do not directly improve the durability of foam, but they have a certain indirect effect on the long-term performance of foam materials, especially when subjected to repeated pressure, deformation or harsh use environment. Specifically, the role of slow-rebound foam openers is:
Delaying rebound: Slow-rebound foam openers can slowly restore the foam to its original state after being subjected to pressure or deformation, thereby reducing the stress concentration of the foam material during use and avoiding material rupture or deformation due to too fast rebound.
Slowing down fatigue loss: By making the foam rebound process smoother, the fatigue loss of the foam material caused by rapid rebound can be reduced, thereby extending the service life of the foam.
Improving comfort: In some application scenarios, slow-rebound foam can provide better comfort and support effects, and reduce aging or wear caused by frequent pressure changes.
Improving material uniformity: Slow-rebound foam openers can sometimes help the foam structure to be more uniform, avoid local excessive compression or excessive expansion, and further improve the stability and durability of the material.
In summary, slow-rebound foam openers indirectly contribute to the durability of foam by improving the rebound characteristics of foam and reducing frequent stress effects, but they themselves do not directly change the basic physical properties of foam materials.
