A History of Liquid Silicone Rubber

Liquid Silicone Rubber (LSR) is a synthetic rubber compound that has become increasingly popular in recent years due to its unique qualities and versatility. But where did LSR come from, and how did it become such an important part of modern manufacturing?

In 1824, the Swedish chemist Jöns Jackob Berzelius first isolated silicon. Taking his research further, he heated silicon in chlorine, which had an effect of a vigorous combustion. The result was silicon tetrachloride, one of the materials still used to produce silicones.

In the mid-20th century, researchers began experimenting with various silicone-based materials. At the time, silicone was primarily being used in the medical industry for things like prosthetics and pacemaker coatings. However, scientists soon realized that silicone had a number of other properties that could be harnessed for a variety of applications.

One such property was the ability to create a liquid rubber compound that could be molded into virtually any shape. This new material, known as Liquid Silicone Rubber, quickly gained popularity in the automotive industry where it was used to create seals, gaskets, and other components that needed to withstand extreme temperatures and harsh chemicals.

Over the next few decades, LSR continued to evolve and improve. In the 1990s, for example, researchers discovered that adding platinum to the silicone compound could speed up the curing process and improve the material’s overall performance. Today, LSR is used in a wide variety of industries, from medical devices and consumer products to aerospace and automotive applications.

So what makes LSR so special? For one, it’s incredibly durable and resistant to a wide range of chemicals and environmental factors. It’s also highly flexible and can be molded into complex shapes with minimal waste. Plus, because LSR is a liquid when it’s injected into a mold, it can easily fill even the most intricate cavities and details.

Overall, the history of LSR is a testament to the power of human ingenuity and innovation. By combining silicone with other materials and refining the manufacturing process over time, scientists and engineers have created a material that’s versatile, reliable, and incredibly useful in a wide range of applications. As technology continues to advance, it’s likely that we’ll see even more exciting developments in the world of LSR in the years to come.
