What are Foam Extrusions?
Foam extrusions are made through a process that involves extracting a product with several variables that relate to each other. Through this process, one variable results in a ripple effect in order to create a final product. Foam extrusions are made possible with the use of precision equipment, because special foam controls the process variables. As a result, uniform quality can be maintained. The process of creating foam extrusions has been around for many years. During World War II, Styrofoam logs were made using foam extrusion processes. These logs were used as floats for anti-submarine nets, as well as for rafts for the military troops. The Dow Company marketed the first commercialized extruded foam, uncross-linked foam, in 1958. Two years later, the Japanese were able to extrude cross-linked foam with the use of chemical blowing agents. France also pioneered the extrusion of polyvinyl chloride (PVC), which involved cooling the surface to form a solid skin. This method is widely k
