Vytex Natural Rubber Latex comes from the "Hevea brasiliensis" rubber tree, which is primarily cultivated in Southeast Asia. Natural rubber latex is a cloudy white liquid collected by cutting a thin strip of bark from the tree and allowing the latex to be secreted into a collection cup over a period of several hours. After collection, the latex is treated with ammonia to prevent coagulation and is transported to a processing facility for concentrating and compounding.
