Rubber laminate and flexible hose using same
Abstract:
A non-crosslinked rubber laminate which is a rubber laminate includes a butyl rubber-containing layer stacked with an ethylene propylene diene rubber and/or ethylene propylene rubber-containing layer, wherein such non-crosslinked rubber laminate is characterized in that the ethylene propylene diene rubber and/or ethylene propylene rubber-containing layer is a rubber-containing layer that contains a low-molecular-weight polyolefin, a phenolic resin, and a crosslinking agent, where: the low-molecular-weight polyolefin is contained by 40 to 70 parts by weight, the phenolic resin is contained by 1 to 4 parts by weight, and the crosslinking agent is contained by at least 1 part by weight, relative to the ethylene propylene diene rubber and/or ethylene propylene rubber constituting a total of 100 parts by weight. An air conditioning hose made of the rubber laminate, for example, can accommodate POE-based lubricating oils and retain vibration absorption characteristics.
