Silicone is renowned for its resistance to high temperatures and is used in many industries where this property is a must. The material can maintain its structural integrity when exposed to intense heat and can also repel liquids. This makes silicone particularly useful where hygiene is of paramount importance, such as in beverage, food and pharmaceutical production. In this blog post, we’ll take a look at what temperatures this versatile material can stand.

General use silicone

Silicone is made into a number of forms, including sheeting, o-rings, gaskets, seals and washers. Many of the applications these items will be used will take place in high or low temperature environments, requiring considerable durability. Therefore general purpose silicone sheeting is designed to withstand a temperature range between -60 and +230°c. TYM stock a wide range of this silicone sheeting in a selection of thicknesses and colours that can suit your needs. We also offer silicone sheeting that is metal detectable, ideal for use in food production lines where seals can degrade and get into the food. Metal detecting sensors can quickly locate the material and save many hours of lost production time. 

High temperature silicone

However, there will be situations where even more extreme temperatures will be encountered and more durable silicone is required. High temperature silicone is often used in the automotive industry and even on industrial furnace gaskets. For these more demanding applications, TYM also stocks an even more resistant form of silicone. This high temp silicone sheeting has all the properties of general purpose silicone sheeting, but with higher resistance to extreme heat conditions.

Thanks to its construction, this high temp silicone can intermittently withstand temperatures of 270 and 300°c. It is also fully compliant to FDA 177.2600 and EC1935/2004. This sheeting can be used to make strips, gaskets, washers, seals and can even be purchased off the roll.
