Stopper Silicone

Is the perfect stopper silicone based? Well, that is not an easy question because every stopper, silicone or not, is great for a certain application. While it is true that you won’t go wrong with a silicone stopper, we want to tell you why that is.

For starters, silicone is one of the most versatile rubbers used to manufacture stoppers, grommets, plugs, and other products. It comes with many useful characteristics and features, one of which is excellent electrical insulation. 

So, if you want a non-conducive stopper silicone is the way to go. But, that is hardly the extent of the usefulness of a silicone stopper. Arguably the best thing about silicone is its low thermal conductivity and excellent thermal stability. Loosely translated, that means that a rubber stopper made of silicone will easily withstand both low and high temperatures, ranging from negative 70 degrees Celsius, all the way to plus 270 degrees Celsius, without becoming too cold or too hot, nor being damaged by the changes in environment temperature. That alone makes it suitable for many industries around the world. For instance, silicone parts are often used in the automotive industry. You can find silicone grease, tubing and stoppers in a lot of vehicles, as well as automotive manufacturing facilities.

Another common environment where we can find stopper silicone is the chemical industry. Laboratories and research facilities are heavily dependent on these products. Seeing how they are dealing with abrasive chemicals, amongst many other things, they require a silicone stopper due to its chemical stability and non-reactivity. Also, biochemical labs researching samples and conducting research must make sure that their samples and projects are safely sealed inside of their containers, which is exactly what a stopper such as this one does. A stopper made from silicone adheres to glass perfectly, providing a vacuum-tight seal and protection.
