Abstract
A foaming composition comprising a melt processible fluoropolymer, and a chemical foaming agent, where the chemical foaming agent is ammonium polyphosphate.
Claims
exact text as granted — not AI-modified1 . A dielectric insulating layer for an electrical cable comprising:
a foaming composition, said foaming composition made from the following steps: blending a foaming composition of a melt processible fluoropolymer, and ammonium polyphosphate as a chemical foaming agent above the temperature needed to melt the fluoropolymer and below the temperature needed to decompose the chemical foaming agent; and extruding said composition above the temperature needed to decompose the chemical foaming agent.
2 . A cross spacer for an electrical cable comprising:
a foaming composition, said foaming composition made from the following steps: blending a foaming composition of a melt processible fluoropolymer, and ammonium polyphosphate as a chemical foaming agent above the temperature needed to melt the fluoropolymer and below the temperature needed to decompose the chemical foaming agent; and extruding said composition above the temperature needed to decompose the chemical foaming agent.Join the waitlist — get patent alerts
