Verfahren und Vorrichtung zur Herstellung von polymerem Schaumstoff.
摘要
A continuous process is provided for the preparation at ambient temperatures of a polymer-based foam sheet in which the foam is produced from a reaction product capable of curing at ambient temperatures formed by the reaction of a reactant composition comprising a prepolymer, such as an isocyanate-capped polyether, and water. The process includes providing a continous substrate (5); depositing said reaction product onto said substrate (5); compressing said reaction product by subjecting said product to at least one compression of a predetermined degree after said reaction product has creamed but prior to the time said reaction product has finally cured; and finally curing said reaction product. In addition to the above process an apparatus for the production of the aforesaid foam is also described.
