High Temperature Silicone Sheet

High temperature silicone rubber sheet, 60° shore A hardness. For applications requiring the typical properties of silicone, but with high heat resistance, Silex THT is ideal. Capable of withstanding many hours at 300°C and 315°C intermittently, this sheet is a great choice for extreme conditions. 

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

Designers and engineers are reminded that silicone requires the presence of oxygen in order to perform at such extreme temperatures, the absence of which will result in reversion and deteriorate at a much lower temperature. Using silicone at the extremes of its 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.

Supplied in 1m square sheets. Hardnesses from 40 to 80 Shore A and a range of colours are also available on request.
