Abstract:
A laminate comprising an olefinic thermoplastic elastomer which comprises:(a) a substratum layer comprising an olefinic thermoplastic elastomer composition (A) having the following characteristics {circle around (1)} to {circle around (3)}: {circle around (1)}9&lE;Yâˆ’0.43X&lE;27â€ƒâ€ƒ(1) â€ƒwherein X denotes the JIS A-hardness value, a dimensionless value, of the olefinic thermoplastic elastomer composition determined according to the prescription of JIS K6301 and Y represents the compression set value, expressed by %, of the olefinic thermoplastic elastomer composition determined according to the prescription of JIS K6301 under a condition of 70Â° C. and 22 hours, {circle around (2)} a tensile strength value in the range from 5 to 30 MPa determined according to the prescription of JIS K6301 and {circle around (3)} elongation set value of 18% or less determined according to the prescription of JIS K6301, and (b) a surface skin layer comprising an ultra high molecular weight polyolefin composition (B) having an intrinsic viscosity [&eegr;] measured in decalin at 135Â° C. in the range from 3.5 to 8.3 dl/g.
