Our wide selection of rubber products and organizational tools, including digital image wrist bands, workout bands, silicone bracelets, and more, are centered around what we’ve done best for nearly 100 years: custom rubber bands.

How Are Rubber Bands Made?

What Gives Rubber Bands Their Strength? | Alliance Rubber (9)Rubber 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.

FAQs

What Gives Rubber Bands Their Strength? | Alliance Rubber? ›

Vulcanization – The curing process of rubber which cross-links the molecules into a strong chain, giving the rubber its stretch and strength.

What makes rubber bands last longer? ›

When a rubber band is in its relaxed state it is very unordered, and will cool when going from a structured state to a relaxed state. So when a rubber band is put in the refrigerator it makes the polymers even more relaxed due to the way they behave in the cold.

What makes rubber bands snap? ›

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.

Why do rubber bands get hard? ›

Over time, rubber loses its ability to stretch, becoming hard and brittle. This process of perishing occurs because exposure of the rubber to light and air induces chemical changes in the polyisoprene over time.

Why do my elastics break so easily? ›

Some rubber bands are made with a cheaper, thinner elastic, which may be the reason they keep breaking. Some people will use two, three (or more) rubber bands on top of each other to make them stronger. But, the bands may still end up breaking -- it just takes a little longer.

Are thicker rubber bands stronger? ›

Rubber band sizes are often represented by a numbering system, such as 8, 16, 32, and 64. Each number corresponds to a specific size, with higher numbers indicating larger and stronger bands.

How to prevent rubber from deteriorating? ›

The higher the temperature, the faster the rate of deterioration. Cooler conditions, therefore, promote longevity. Avoid hot lights, proximity to any heat source, or any storage or display practice that heats objects. Ideally, rubber and plastic objects should be stored in cold, dark, dry, and oxygen-free conditions.

What happens when you put rubber bands in boiling water? ›

Normally, when a material gets hotter, the molecules vibrate more intensely. Since they bump into each other harder, this causes the material to expand a bit. This phenomenon is called thermal expansion.

Does oil weaken rubber bands? ›

"The essential oil and the rubber are both nonpolar hydrocarbons, so when they come together, some of the rubber dissolves into the oil, causing it to weaken."

What oil makes rubber bands pop? ›

just a drop. of lemon oil on each rubber band and they pop right off | Rubber Hand Experiment | TikTok.

Why do elastic bands go brittle? ›

Moisture content within the material can increase or decrease. The oxygen in the atmosphere can slowly react with the material. The brittleness is primarily due to the changing of the molecular bonds (or phases) in the material.

Do rubber bands expire? ›

Do your rubber bands have an expiry date? Due to the natural properties of the rubber, our bands last between 18-24 months. We have extended longevity by storing our bands in semi-vacuum sealed bags and in a cooler warehouse location.

How to rehydrate rubber bands? ›

boiling water. It will go back to shape immediately.

What does heat do to rubber bands? ›

Rubber bands behave in a manner opposite to that of most solids: They contract when heated, expand when cooled. Further, the length of a stretched rubber band does not return immediately to its original non-stretched length. These behaviors are due to the structure of rubber, being long, loose, twisted chain molecules.

Does twisting a rubber band make it stronger? ›

If one is to consider a rubber band to be used to power a vehicle, using the twisting method does not only make it more efficient, but due to the less of a force it has when being deformed, it would also be able to hold more energy without breaking.

How to make a rubber band more elastic? ›

Also, warm rubber bands are more elastic than cold ones. Like shown here. Since rubber bands wear out faster when being overstretched, you should make them as elastic as possible prior to stretching by warming them up first.

Do stronger elastics move teeth faster? ›

It may be tempting to double up on elastics with the idea that twice the pressure will move the teeth twice as fast – but that doesn't work. In fact, too much pressure can slow down tooth movement and damage roots.

How do you make rubber bands hurt less? ›
