摘要:
The present invention is related to a multi-layered thermoplastic elastomer (TPE) foam. Due to a specific formulation of the multi-layered TPE foam, adjacent layers of said TPE foam can be perfectly adhered to each other without adhesive or thermocompression after foaming. The present invention is also related to a specific process for forming a multi-layered foam.

Provided is a laminate having elastomer layers tightly bonded to each other. The laminate according to the present invention 1 has an acrylic elastomer layer 11 and a fluorine elastomer layer 12 that are bonded to each other. The acrylic elastomer layer 11 is made of an acrylic elastomer composition having an epoxy group-containing acrylic elastomer and an onium salt added and the fluorine elastomer layer 12 is made of a fluorine elastomer composition having a fluorine elastomer and a polyol crosslinking agent added. In the laminate 1, the elastomer layers are bonded tightly to each other even without any surface treatment.

The invention relates to an elastomer laminate comprising three layers, the first layer consisting of a diene rubber composition comprising a first elastomer matrix; the second layer consisting of a diene rubber composition comprising a second elastomer matrix, which second elastomer matrix comprises a second ethylene terpolymer elastomer consisting of an α-olefin and an unconjugated diene and containing more than 10% by mass diene units; the third layer consisting of a diene rubber composition comprising a third diene elastomer with a diene unit mass rate greater than 50%, the second layer being disposed between the first layer and the third layer. A laminate of this type has good resistance to separation of its constituent layers.

The present invention relates to a brake hose including a reinforcing member that has more excellent shape stability, durability, high modulus, and a low deterioration in modulus at a high temperature. The brake hose includes: rubber layers; and a reinforcing member formed between the rubber layers or on the rubber layers, in which the reinforcing member may include a polyethylene terephthalate dip cord that is applied with an initial load of 0.01 g/d to be fixed after being subjected to heat treatment for 15 minutes under a tension of 0.01 g/d at 180 °C and has a creep rate equal to or less than 7.0% when being left for 24 hours while being applied with a load of 0.791 g/d at 100 °C.
