The purpose of this study was to prepare porous rubber film from natural rubber and various water soluble polymers such as polyethylene glycol, starch, and polyvinyl alcohol. Polymer was added and mixed well with rubber latex and the rubber film was formed using the coagulant dipping method. The polymer was finally removed from the rubber film by rinsing with hot water. The rubber film was then tested for tensile strength, air permeability, and water repellency. Scanning electron microscope was brought to observe the film surface. Test results indicated that rubber films made from rubber latex / polymer mix contained a bit larger and higher amount of gaps than natural rubber film. However, these rubber films repelled water well and were impermeable by air when tested on an air permeable tester for fabrics. Cotton fabrics coated with rubber latex / polymer mix at certain concentrations were water repellent and air permeable. These coating materials consisted of rubber latex / polyethylene glycol 5-10 % mix, rubber latex / starch 5 % mix 1 and rubber latex / polyvinyl alcohol 5 % mix and the coating time was 15 seconds. Rubber films made from rubber latex / polyvinyl alcohol mix showed higher tensile strength than natural rubber films while rubber films made from rubber latex / polyethylene glycol or from rubber latex / starch mix showed lower.
