Foam Padding

Closed cell polyethylene foam to line the inside of braces for greater patient comfort

Volara® is a closed cell EVA copolymer foam that is used to line the inside of braces to give greater comfort to the patient. Volara® can be assembled to plastic devices using adhesives or it can be formed around a positive casting and then rigid plastic sheet can be formed around the Volara® to create a direct bond between the foam and the plastic. Volara® is available in a low density, low stiffness grade (four pounds per cubic foot) and a high density, high stiffness grade (ten pounds per cubic foot).

Tech Tip– Volara® can also be used in the fabrication process to help create a vacuum seal.
