Webb20 dec. 2024 · Foam board, also known as foam core or KT board, is a backing material widely used in framing art and photo mounting. It is made of an extruded polystyrene foam board covered on both sides with paper or plastic film. The board is like a sandwich structure. This material is usually white or black in colour. WebbSyntactic foam is a high strength, light weight material that is created by using hollow spheres, typically made of glass, that are bound together with a thermoset polymer. The use of the word foam can be misleading as many people when they think of foam think of something that is weak and flexible. Here the word foam related to the cellular ...
Webb1 dec. 2024 · Thermosetting polyurethane foams (PUs) were introduced at the beginning of the last century as a synthesis product of a polyol and an isocyanate ( synthesis reaction ). Concurrent to the synthesis reaction, a blowing reaction of isocyanate with water provides the blowing agent, CO 2, responsible for foaming the curing matter. WebbThermoplastic foam injection molding charges the polymer melt with a blowing agent that leads to the foaming of the molding compound in the cavity after injection. Together with our partners we develop material compositions and processes for foamed components using both chemical and physical (Mucell® / Direct-Foam) blowing agents.
