The Vietnamese word "dâu cao su" translates to "rubber" in English. It specifically refers to the material derived from the latex of rubber trees, which is used for making a wide variety of products due to its elastic properties.
In a more advanced context, "dâu cao su" can also be discussed in relation to manufacturing, environmental impact (like deforestation from rubber tree plantations), or even in the context of the global economy, as rubber is a significant commodity.
While "dâu cao su" primarily refers to rubber, in some contexts, it can also refer to the rubber tree itself. However, in everyday conversation, it predominantly denotes the material.
