How Are Rubber Bands Made?

rubber band manufacturing processRubber comes from plants and has been used for centuries by numerous individuals and industries. It was discovered by Europeans to erase pencil marks and proved useful for waterproofing, but the commercialization of rubber was a challenge due to its characteristics (brittle in the cold, gooey in the heat). It wasn’t until Charles Goodyear discovered the vulcanization process in 1839 that rubber was able to be stabilized and used for a variety of purposes. Just a few years later, the rubber band was invented.

Today, rubber band manufacturing is a multi-step process. In short, it looks like this:

  1. The latex is harvested and purified, then mixed with acetic or formic acid to ensure the rubber particles stick together. It’s then formed into slabs and shipped to rubber manufacturers.
  2. The rubber is mixed with chemicals to enhance or diminish elasticity, change the color, and more.
  3. It’s put through the milling process, where it’s heated and pressed flat.
  4. The rubber is cut into strips and passed through an extrusion machine.
  5. After the curing process, the rubber is sliced into finished rubber bands.

Rubber bands are useful in schools, retail stores, food and beverage companies, the post office, and so many other places due to their stretchability and elasticity. Rubber bands are stretchy because of entropy, which is a state of disorder. When a rubber band is at rest, rubber molecules are tangled in a random mess, meaning they have high entropy. When you stretch it, the disordered molecules straighten, meaning they have less entropy. Once you let it go, the molecules return to their relaxed state or disorder and high entropy.

As you’ve probably experienced, they can only “bounce back” for so long. Cold temperatures make rubber bands brittle and prone to snapping. Oxygen and UV light break the rubber down over time, and eventually the band loses its elasticity—which is why outdoor rubber bands are typically made to be UV and ozone resistant to help prolong their lifespan. These EPDM rubber bands are made of heavy-duty, non-latex synthetic rubber to withstand harsh and ever-changing environmental conditions.
