In previous posts we already explained in detail the exceptional properties and best applications for the widely used cushion materials EVA and PUR.
In this issue we summarize and compare the important properties and differences between the two versatile materials for you:
EVA & EVA PLUS
EVA is the abbreviation for “Ethylene Vinyl Acetate” and features a fine and uniform foam structure with tiny air bubbles trapped in closed cells.
• Closed cell structure
• Disinfectable (surface washable and resistant to most disinfectant solvents)
• High resilience
• Good durability and sturdiness (good recovery characteristics after compression)
• Tear resistant (ability to withstand stress without obtaining cracks or breaking)
• Thermal moldability
• To relieve pressure-sensitive surfaces
PUR cushions are open-cell structured foams that have viscoelastic, rebouncing properties and are free of PVC, latex, and solvents.
• Open cell structure
• Not desinfectable
• Low resilience
• Good impact absorption (rebounces back to the original material thickness)
• Poor thermal moldability
• For punctual and area relief of pressure-sensitive surfaces
