    •      		Example Cross Section Diagrams:




     Advantages: Good resistance to chafing Resists attack by commonly expected fluids
    Disadvatages: 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)

    Chemical Information:

    Chemical Name: Poly (1-chloroethylene) or Poly (vinyl chloride)
