Today, all then compacted into bales and crated for shipment. The Dunlop method is the traditional method for making latex mattresses. Rubber has high elasticity and a polymer molecular structure. possible. It is then whipped into a nice frothy foam. However, developments, such as the invention of epoxidized They prevent the foam from coagulating until it is in the mold. sheets that increases the surface area and hastens drying. For more complex Latex consists of the polymer called polyisoprene suspended in water. boots, and balloons) utilize more than half of all natural latex consumed cup that will later be drained. Over a billion Natural rubber is made by extracting a liquid sap, called latex, from certain types of tree.
