Unless otherwise indicated, values refer to 2 and 3 mm thicknesses.
Note:
(1) For lower temperatures, please contact our technical office.
(2) The "DIN 3535" test sets the maximum leakage rate at 1 cm³/min. Permeability values are well below this limit.
(3) This test is carried out in order to measure the % surface increase after one minute under a pressure of 60N/mm² at room temperature.
(4) This test is carried out in order to measure the % surface increase under a load of 30 N/mm² after having heated the gasket for 45 min. as to gradually increase its temperature to 150°C, and maintaining it for 30 min.
