“Gist”: Use of pentaethylenehexamine to reduce aldehyde emissions
Why it is interesting: As mentioned in previous posts, the reduction of formaldehyde and acetaldehyde emissions from polyurethane foams remains a pressing environmental issue. According to this patent application the problem can be solved by adding some (1 pphp in the examples) of pentaethylene hexamine to the polyol formulation. The polyamine will act as a formaldehyde scavenger and has some advantages over the prior art. In the related case WO2015/071063, the pentaethylene hexamine is first reacted with guanidine chloride before being added to the formulation.
