WM44A0111-18-2 is a Single Conductor Tin Coated Copper alloy, 18 AWG Unshielded Unjacketed, 150c radiation crosslinked polyalkene Rated for 600v

SPEC 44 wire has a dual wall construction which combines the outstanding physical and electrical characteristics of radiation crosslinked polyalkene with the excellent mechanical and chemical properties of radiation cross-linked polyvinylidene fluoride (PVDF). The result is a wire insulation system that offers a 150°C [302°F] temperature rating, small size, light weight, solder iron resistance, and resistance to most solvents, fuels and lubricants. SPEC 44 wire and cable is highly flame retardant, non- melting, does not cold flow, and though mechanically very tough, is easy to handle and install using conventional tools.
