Abstract

Disclosed is a spacer for an optical fiber cable, which is produced by melting and extruding a mixture comprising (1) a polyethylene and (2) a polyethylene wax, wherein the polyethylene (1) has a density ranging from 940 to 980 kg/m<SP>3</SP> (as measured by the density gradient tube method in accordance with JIS K7112) and a MI value ranging from 0.01 to 0.3 g/10 minutes (as measured in accordance with JIS K7210), and the polyethylene wax (2) has a density ranging from 890 to 980 kg/m<SP>3</SP> (as measured by the density gradient tube method in accordance with JIS K7112) and a number average molecular weight (Mn) ranging from 500 to 4,000 in terms of polyethylene as measured by GPC and satisfies the relationship expressed by the formula (I). B ≤ 0.0075xK (I) [wherein B represents a content (mass%) of a component having a molecular weight of 20,000 or more in terms of polyethylene in the polyethylene wax as measured by GPC; and K represents a melt viscosity (mPa‧s) of the polyethylene wax at 140 DEG C. Also disclosed is a method for producing the spacer.
