Physical properties
* The figures show the average values obtained in the world well-known test institutes.
** At below -57 ° C EPDM rubber hardens, but it does not affect the thermal conductivity or water vapor permeability.
In heating applications EPDM rubber withstand 125 ° C continuously, and glue up to +100 ° C
*** Water vapor permeability test was conducted according to test method ASTM E96 by drying test methods at 37.8 ° C
