Reprinted from the Proceedings of the Polyurethanes

2019-7-18 proaches including using a two -roll mill were also demon - strated on a pilot-plant scale. The last published major efforts conducted in foam rec y cling were reported in 1995 - 1997. This has been the subject of a recent technical re-view [7]. Some of the concl usions of that work were: 1) the economics of foam recycling by means of grinding.

Methods for polyurethane and polyurethane

During the early 1990s two-roll milling was found to give the best result for flexible PU foam grinding, whilst for rigid PU foams ball mills may yield particle sizes as small as 85 m. One factor that limits the amount of scrapped PU foam that can be recycled by regrinding is the viscosity of the polyol/fine particle mixture that can be.
