High Temperature Silicone Sheet

For applications requiring the typical properties of silicone, but with high heat resistance, our “THT” silicone sheet is the ideal solution.

Capable of withstanding many hours at 300°C and intermittently at 315°C, THT silicone sheeting is the best choice for such extreme conditions.

Designers and Engineers are reminded that silicone requires the presence of Oxygen in order to achieve such extremes. In the absence of Oxygen, silicones will suffer reversion and deteriorate at a much lower temperature.

Using silicones at the extremes of their capabilities will naturally limit the life of the product through heat ageing and application performance can vary depending on the stresses applied at the time.

As an example, customers who want to use a silicone product for long periods at +240°C/+250°C will benefit from using a +300°C silicone rather than one for +250°C.

Fully compliant to FDA standard 177.2600 and EC 1935/2004, THT silicone sheets are suitable for applications requiring direct food contact.

All of our silicone sheet products are available plain or adhesive backed and can be supplied in sheet form or converted into strips, seals, washers, gaskets and fabricated articles.

Standard stock sheet is available in the following thicknesses and colours:-
