Abstract
The combination of fluoropolymer processing aid with foam cell nucleating agent gives a combined processing aid that is far superior to either individually when used in the extrusion of melt processible polymers.
Claims10
A melt processible composition comprising a melt processible polymer, about 0.001 to about 5 wt. % foam cell nucleating agent, and about 0.001 to about 5 wt. % fluoropolymer processing aid.
A coating for a conductor, said coating comprised of a melt processible composition comprising melt processible polymer, 0.001 to 5 wt. % foam cell nucleating agent, and 0.001 to 1 wt. % fluoropolymer processing aid.
A melt processible composition comprising a melt processible polymer, about 0.01 wt. % to about 10 wt. % foam cell nucleating agent, and about 0.01 wt. % to about 10 wt. % fluoropolymer processing aid.
