Advantages: Good resistance to chafing
Resists attack by commonly expected fluids
Disadvantages: Out-gassing of harmful HCl
Loss of Dimension and Weight over time
Discolors with moderate heating
Produces harmful gasses and smoke when it burns
Very heavy: 6.8 pounds/1000 feet (10 kg/km)
6.3 pounds/ 1000 ft (9.3 kg/km) without a glass insulator layer
In some instances the nylon has been shed due to splitting from manufacturing flaws
Dissolves or softens in solvents used for PVC piping – e.g., methyl ethyl ketone and tetrahydrofuran
Other Information: Often stabilizers and plasticizers are added
Thermoplastic polymer unless cross-linked
Only insulation with MIL-W-16878/1 through /3
Moderate radiation resistance (~ 10^7 Rd)
