High Strength / Low Temperature Grade silicone sheeting is designed to be used in applications where the material will see extreme low temperatures. (-130 degrees F) and the highest physical properties are also needed. The tensile strength and tear strength of this material is much higher then the Extreme Low Temperature General Purpose Grade. The material is available in continuous rolls or sheets. It is also resistant to extreme high temperatures, and is proven to be an excellent gasketing material. Available in many colors. This material is made to order only. See attached DSP SOLIDS Specialty Grades price list. 

The given values are typical properties and are provided for information only. They should not be used to set specification requirements. It is up to the end user to determine whether the material is suitable for the intended application.
