Wärmeschrumpfbarer Schaumstoffschlauch, und Verfahren zur Herstellung desselben
摘要
A method of manufacturing a heat-shrinkable foam tube, wherein a two-layer tube, having a foaming agent outer layer and non-foaming inner layer, is extruded and heated simultaneously to activate the foaming agent. This process condenses the two steps of extruding and foaming into one step and results in a tube which can be manufactured to exact and consistent standards and be shrunk onto a pipe at a low temperature in a short period of time. <IMAGE>
