The VPF™ process is based on continuous foaming in an airtight enclosure, where flexible foams are produced under controlled atmospheric conditions of under or overpressure.

​

The VPF™ process requires no auxiliary blowing agents, such as Methylene Chloride, Acetone etc. These blowing agents are replaced by the effects of vacuum.

The foaming gases given off during the VPF™ process, are very small in volume and can be filtered through an activated carbon filter which makes the process completely clean, exceeding the most stringent environmental regulations by far.
