High-purity silicone rubber soft tubing

High-purity silicone rubber soft tubing

High-purity silicone rubber soft tubing is an increasingly sought after type of tubing because high-purity silicon is used in many industries. During the production of many advanced technologies, high-purity silicone rubber soft tubing is used because high-purity silicone guarantees the best performance and is suitable even for very complex and sensitive industries such as those involved in the production of aircraft, space equipment and the like.

High-purity silicone rubber soft tubing is also characterized by a special softness that most other tubing does not have, which allows a special level of manipulation. Since it is soft, which means that the hardness is often below the average hardness which is mostly 30-60 Shore A, it can fit in places where harder tubing could not. Since it has good chemical stability as well as flame retardancy it can be exposed to various chemicals, even flammable ones. High-purity silicone is resistant to various temperatures, which allows it to be used in the aforementioned aerospace industries. High-purity silicone can be exposed to temperatures below minus fifty degrees Celsius and above plus two hundred and fifty degrees Celsius.

Due to its purity, it is suitable for use in the food industry, as it is FDA approved, and in these cases transparent tubing is especially popular to have insight into the procedure.

Any weather conditions will not damage it, which is another important feature that affects the popularity of silicone. High-purity silicone rubber soft tubing is available in different sizes, and you can also order customized if you need different wall thickness, for example, due to contact with certain chemicals and the like. The outside and inside diameters, along with the thickness of the wall, are the most important measures you need to know before using this type of tubing. High-purity silicone rubber soft tubing is mostly transparent or white. But it can be in whatever color you need.
