1For operating temperatures below -180°C, special attention must be given to the system design and craftsmanship during installation to ensure that the material does not come in contact with liquid oxygen. For further information and support, please contact Technical Services. 2Measured under a load of 1.5 kPa (0.22 psi). 3Test performed with a preload of 13.8 kPa (2 psi). 4Shelf life (maximum storage time) is limited to ensure that only currently manufactured products are installed on projects. This limitation is restricted solely to storage of the product and does not affect the lifetime of product after it has been installed. | |||||||||||||||||||||||||||||
