: The tube will slightly expand in size and volume as it reaches equilibrium.
: While toughness increases, the absolute tensile strength and stiffness (modulus) decrease.
What’s the Difference?™: Nylon 6 vs. Nylon 66 - UL Prospector nylon matures tube
if surface stiffness or visible cracks appear. 3. Factors Accelerating Degradation (Aging)
Yellowing, surface cracks, loss of elasticity, and brittleness. : The tube will slightly expand in size
Optimal state for standard operation in pneumatic or fluid systems.
: Impact resistance can improve by up to 10 times as the material absorbs water. loss of elasticity
Freshly extruded nylon tubing is "Dry As Molded" (DAM) and is at its most brittle. As it "matures" by absorbing ambient moisture, it undergoes several shifts:
