ABSTRACT:
Melt processable halogen-free low smoke wire coating compositions are provided which utilize a polyimide-siloxane, an effective amount of a plasticizer and hydrated zinc borate. The melt processable halogen-free low smoke blends can satisfy the low smoke requirements for plenum wire as shown by an Ohio State University test value of total smoke after 5 minutes of less than 100.
