Balatá is a natural
latex
Latex is an emulsion (stable dispersion) of polymer microparticles in water. Latices are found in nature, but synthetic latices are common as well.
In nature, latex is found as a wikt:milky, milky fluid, which is present in 10% of all floweri ...

Description
The ''Manilkara bidentata'' is a large tree, typically growing to a height of 30–45 meters. The tree typically measuring 10–20 cm long, produces small white flowers at the onset of the rainy season. It bears an edible yellow berry that contains one or two seeds. The latex extracted from the tree is thick and rubbery, resembling

Properties and uses
Balatá is a hard, rubber-like material derived from the dried latex of the ''Manilkara bidentata'' tree, primarily found in Guyana and the West Indies. The latex is harvested by making zigzag incisions in the tree's bark, allowing the milky fluid to flow into collection cups. The latex is then coagulated in trays to form a durable substance.
Like gutta-percha, balatá is tough, inelastic, leathery, and water-resistant, becoming pliable when heated. Due to these comparable properties, it has historically served as a cost-effective alternative to gutta-percha, particularly in manufacturing golf balls and industrial machine belts.
The latex is harvested in a manner similar to that of the rubber tree (''Hevea brasiliensis''). Once extracted, it is dried to form an inelastic rubber-like material. One notable historical use of balatá was in the production of high-quality golf balls. These balls, covered in balatá, were known for their high spin rate, although they did not travel as far as those with modern synthetic covers like Surlyn. Due to the material's tendency to wear down quickly, balatá-covered golf balls have become obsolete and have been replaced by more durable materials such as Surlyn and polyurethane.
