new How to process the SAP extracted from rubber trees into rubber materials?
First, a worker uses a special tool to scrape a slit in the rubber tree. Soon the white liquid in the heart of the tree begins to drip down the wound into the ceramic pot below. This is a rubber plantation in Thailand, where thousands of rubber trees grow to provide a continuous supply of raw rubber for the factory every year. After six hours of collecting, the workers put all the branches into the container and then added a percentage of acetic acid. When the rubber liquid is mixed with the strong corrosive liquid, it will soon be condensed into a plastic paste.
