How to select a high quality memory foam production
22 meters memory foam foaming production line What material is memory foam? Why is it widely used in bedding ? Memory foam is also called space foam, inertia foam or sticky elastic foam. It is actually soft polyurethane kick-back foam. Polyurethane is a high polymer synthetic material made by the chemical reaction between isocyanic acid and oxhydryl of Polyether polyol. The reaction makes many high polymer chemical compounds composed of NHCOO radical group. Slow kick-back Polyurethane foam is more than common soft Polyurethane foam because it combined with special Polyether, adding soft part and hard part to foam and taking on two different shapes in room temperature(Soft part——kick-back shape;Hard part——glass shape). When stressed, the soft part is easily changing shape while the hard part prevents it, thus enable the foam to slowly kick back. The above can account for the following scene: slow kick-back foam changes shape when stressed and an imprint(e.g. handp...
