LAMINATE WITH SILICONE RUBBER LAYER AND ENB-BASED EPDM LAYER

摘要

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).;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 MV₁₊₄(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 MV₁₊₄(125°C) of ≥60, and a low viscosity rubber component with Mooney viscosity MV₁₊₄(125°C) of ≤30.;COPYRIGHT: (C)2013,JPO&INPIT
