Low-temperature silicone seals – how and where they are used

Low-temperature silicone seals – how and where they are used

When the temperature resistance properties of silicone seals are discussed, the focus is usually on their resistance to high temperatures, however a key feature for a range of industry manufacturers and their applications is the ability to operate at very low temperatures. Our silicone compounds are so versatile that we can create seals that are highly resistant to these low temperatures, this increases the effectiveness of the seal dramatically and therefore the application itself.

Choosing the correct material for sealing is an important decision for any application, and therefore understanding the application requirements is critical. Low-temperature applications usually have vital functions, and the performance and durability of your seal will depend on the material specifications you select.

Materials that are not designed for low temperatures can harden, become brittle and weaken when used for low temperature applications, this impacts the integrity of the seal, negatively affecting its ability to provide the necessary level of compression and sealing. This decision to use material not designed for the application requirements created defects that can lead your seal to leak, compromising the performance of your application.

Why manufacturers are choosing low-temperature silicone seals

Low-temperature silicone materials protect the seal against critical degradation and loss of functionality at temperatures as low as -100°C, meaning they do not harden, stiffen, or lose their sealing ability which avoids damaging malfunctions.

As such, this material provides manufacturers with a level of quality and durability that they can rely on and is one that safeguards the performance of their applications and brand.

The type of manufacturers that rely on low-temperature silicone seals

Companies for which low-temperature silicone seals are an essential component include manufacturers from the aerospace, building and construction, medical, food and drink, and pharmaceutical industries.

In the pharmaceutical industry, one area in which these seals are used is vaccine storage, the importance of which has been particularly critical in the roll-out of the COVID-19 vaccination programme. In the food and drink sector, low-temperature silicone seals are used by refrigerator and freezer manufacturers.

Notably, while low-temperature silicone is a specialist material, the design, development and manufacturing process are standard practice for our silicone technicians. This means that, with the right expertise, it is straightforward to create low-temperature silicone seals to meet exact application specifications.

Low-temperature silicone and your choice of seals supplier

When you are selecting the low-temperature silicone seals for your application, it is important that you are working with the right silicone rubber component supplier.

You should always choose a specialist silicone extrusion manufacturer that offers a full range of silicone seal design, development, and production services.

This type of partner will have the skills and experience, the flexibility and adaptability, and the equipment and technology that will help ensure that your low-temperature silicone seals meet your exact specifications and that your application performs to the highest standard.
