NTRK

ntrk

NTRK is a thin wall sleeving with an extremely good tensile strength making it ideal when a high degree of protection of wires or components is required. Manufactured from cross-linked Kynar¨, NTRK is transparent, non burning and possesses excellent resistance to fuels, solvents and chemicals.

It also has an operating range of -55¡C to + 175¡C and complies with MIL-1-23053/8, UL224 VW 1, CSA and Def Stan 59-97 type 3. Kynar¨ is a trade mark of Elf Atochem.
