The National Shipbuilding Research Program. 1987 Ship Production Symposium. Paper Number 23: A Low Toxicity Insulation Material for Shipboard Piping -- Non-Halogenated Polyphosphazene Foam

Abstract

A flexible, fire retardant, chlorine-free polymer foam with applications to pipe insulation has been tested for ship producibility. The new material, Non-Halogenated Phosphazene (NHP) foam, is based on Phosphorus-Nitrogen linkages (Phosphazene) with non-halogenated organic groups attached to produce selected engineering properties. The material tested is flexible, fire retardant, and produces less toxic combustion products than conventional plastic pipe insulation material. Producibility tests have demonstrated the new material to be equivalent in handling characteristics to conventional material which uses PolyVinyl Chloride in its formulation. The use of the new pipe insulation offers a prospect of removing over 1,400 pounds of elemental Chlorine from some surface ships now in production. Removal of Chlorine is in keeping with the objective of producing ships with improved fire protection and safety.
