ABSTRACT:
A water blocking gel which is compatible with polyolefin optical fiber cable buffer tubes is disclosed. The water blocking gel comprises a polyolefin oil, wherein only a very small fraction of the polyolefin species have a molecular weight below about 2000. The gel also includes a thixotropic agent, and a thermal oxidation stabilizer. The gel is relatively low cost, does not cause substantially swelling of the polyolefin buffer tubes in contact therewith and does not degrade the buffer tube's physical properties.
