The term 'Rubber Tree Sap' refers to the sap of the rubber tree, which is a tropical tree native to South America. The sap is composed of two main components: LATEX and RESIN. LATEX is a milky white liquid that is harvested from the tree by making incisions in the bark. RESIN is a sticky, yellowish substance that is also found in the sap. Both LATEX and RESIN are used in a variety of products, including rubber, paint, and adhesives.
