Latex

materials · rubber · chemistry

From trees and plants. Natural latex comes from rubber trees and other plants as a milky sap. When you tap the bark of a rubber tree, this sticky liquid oozes out and can be collected.

Tiny particles in water. Latex is actually an emulsion, meaning it's made of millions of microscopic particles of polymer (a type of plastic or rubber) mixed throughout water. This is what gives latex its creamy, milky appearance.

Made in factories too. Scientists can create synthetic latex in laboratories by combining chemicals, which means we don't always need to harvest it from plants. This artificial latex is used in countless everyday products.

Becomes rubber and more. When latex dries out or is processed, it transforms into rubber that's used for balloons, gloves, erasers, and waterproof coatings. This transformation happens through a process called vulcanization, which makes rubber stronger and more stretchy.

Safe and useful. Latex is flexible, water-resistant, and durable, which is why it's perfect for making everything from medical gloves to paint to bouncy balls. Its natural resistance to water makes it especially valuable for protective gear.
