Abstract
The object of the present invention is to provide an elastomer composite creating a molded article having excellent heat resistance, anti-leakage and needle retaining properties. To attain the object, the present invention provides an elastomer composite comprising 100 parts by mass of a block copolymer mixture containing 10 to 90 parts by mass of a block copolymer A, and 90 to 10 parts by mass of a block copolymer P, with the total amount of said block copolymers A and P being 100 parts by mass, 100 to 300 parts by mass of a softener B, having a kinetic viscosity in the range of between 50 and 500 centistokes (cSt) at 40° C., 1 to 50 parts by mass of a propylene polymer C, having a modulus in bending in the range of between 1000 and 3000 MPa, and 1 to 50 parts by mass of an aromatic polymer D.
