Latex Foam and its applications
by Boontham Nithi-Uthai, consultant
Latex foam was industrially created in 1929 by Dunlop Rubber. The latex was foamed with fatty acid soap and gel by using sodium silico fluoride. The process is now known as the Dunlop process. The method for making this type of foam can be a simple cake mixture. The mold for foam is also a simple mold made from aluminum, stainless steel or resin, or even plaster of paris. Vulcanization can utilize a simple steam oven or hot air oven, or sometimes self-curing takes place if using the correct type and amount of sulfur and accelerators.
