Die aus den schumbaren Polymerisaten hergestellten Schaumstoffe werden bevorzugt zur Wrmeisolation eingesetzt. The foams produced from the foamable polymers are preferably used for heat insulation.doi:EP0357934 A3SPEIKAMP HANS-DIETER DREP
A polymer is achemical compoundwith molecules bonded together in long, repeating chains. Because of their structure, polymers have unique properties that can be tailored for different uses. Polymers are both man-made and naturally occurring. Rubber, for example, is a natural polymeric material that...
Additional Foam Facts How It's Made Memory foam and polyurethane is a polymer created during a chemical reaction between polyol and diisocyanate (two chemicals created from organic compounds). The ratio of polyol to diisocyanate is 2:1 to form polyurethane, though there may be other compounds ...
Also claimed is a polymer compsn. (I) (as above) under a pressure of at least 300 p.s.i., which can be extruded and expanded under atmos. pressure. Also claimed is a process for the prodn. of closed-cell, uncrosslinked foam (I), by heating and melting (a), adding (b) under...
