Flame-retardant molded component

Abstract

A sleeve for the protection of electrical wires or pipes formed from a flame-retardant nylon or polyester monofilament wherein the monofilament is formed by a process comprising the steps of compounding a mixture consisting essentially of 5 to 20 weight percent melamine cyanurate and 3 to 10 weight percent of an organopolyphosphonate, with the balance being polymer; and extruding as a monofilament the compounded mixture.

1 . A sleeve for the protection of electrical wires or pipes comprising flame retardant polyester monofilament formed by a process comprising the steps of compounding a mixture consisting essentially of 5 to 20 weight percent melamine cyanurate and 3 to 10 weight percent of an organopolyphosphonate, with the balance being a polymer selected from the group consisting of poly(ethylene terephthalate) and poly(ethylene naphthalate); and extruding as a monofilament said compounded mixture.  
     
     
         2 . The flame retardant sleeve of  claim 1 , wherein the flame retardant polyester monofilament comprises from 5 to 15 weight percent of melamine cyanurate.  
     
     
         3 . The flame retardant sleeve of  claim 1 , wherein the flame retardant polyester monofilament comprises 10 weight percent of melamine cyanurate and 5 weight percent of organopolyphosphonate.  
     
     
         4 . A sleeve for the protection of electrical wires or pipes comprising flame retardant nylon monofilament formed by a process comprising the steps of compounding a mixture consisting essentially of 5 to 20 weight percent melamine cyanurate and 3 to 10 weight percent of an organopolyphosphonate, with the balance being a polymer selected from the group consisting of Nylon 6, Nylon 12 and Nylon 66; and extruding as a monofilament said compounded mixture.  
     
     
         5 . The flame retardant sleeve of  claim 4 , wherein the flame retardant nylon monofilament comprises from 5 to 15 weight percent of melamine cyanurate.  
     
     
         6 . The flame retardant sleeve of  claim 4 , wherein the flame retardant nylon monofilament comprises 10 weight percent of melamine cyanurate and 5 weight percent of organopolyphosphonate.  
     
     
         7 . The flame retardant sleeve of  claim 4 , wherein the flame retardant nylon monofilament polymer is Nylon 6.
