Description
Rubber Latex – Natural Polymer for Tires, Medical Products, and Industrial Goods
Introduction
Rubber latex is a milky white fluid extracted from the bark of the rubber tree (Hevea brasiliensis). It is the primary raw material for producing natural rubber, which is widely used in tires, gloves, medical equipment, footwear, and numerous industrial products.
Rubber latex is one of the most important industrial agricultural products globally, especially in tropical regions where rubber plantations are widely cultivated.
After processing, latex is coagulated and converted into sheets, blocks, or concentrated forms used in manufacturing.
Product Overview
Rubber latex is harvested by tapping rubber trees and collecting the sap. It is then processed into:
- Natural rubber sheets
- Latex concentrate
- Solid rubber blocks
These forms are used in multiple industries including automotive, healthcare, and construction.
