Abstract

A jacket for an outside plant communication cable is made from a resin of an impact-modified polypropylene copolymer compounded with UV stabilizers. The resin has the characteristics of low cost, low post-extrusion shrinkage, high melting temperature and increased crush and abrasion resistance. The UV light stabilizers may include UV absorbers, quenchers, and/or hindered amine light stabilizers.
