<p><P>PROBLEM TO BE SOLVED: To provide a laminate that can be substituted for a silicone rubber laminate using a conventional DCP (Dicyclopentadiene)-based EPDM (Ethylene Propylene Diene Monomer). <P>SOLUTION: The laminate is provided with the silicone rubber layer, and an EPDM layer containing only 5-ethylidene-2-norbornene (ENB) as a third component. Preferably, Mooney viscosity MV<SB POS="POST">1+4</SB>(125°C) of an unvulcanized mixture for an ENB-based EPDM layer is≥35. Preferably, the unvulcanized mixture contains a high viscosity rubber component with Mooney viscosity MV<SB POS="POST">1+4</SB>(125°C) of≥60, and a low viscosity rubber component with Mooney viscosity MV<SB POS="POST">1+4</SB>(125°C) of≤30. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
