We can bond two low density flexible polyurethane foams using heat (+180degC) and pressure without adhesives. Although the process works most of the time, we sometimes have problems in getting a good bond. Is there any information on why polyurethane can bond to itself (without adhesives)using...
We are able of form a bond between two flexible PU foams using heat (+160 degC)and pressure without using a PU adhesive. Does anyone know why a bond between two PU foams can be achieved using this method?
