Nylon Matures Tube -

What’s the Difference?™: Nylon 6 vs. Nylon 66 - UL Prospector

if surface stiffness or visible cracks appear. 3. Factors Accelerating Degradation (Aging) nylon matures tube

: While toughness increases, the absolute tensile strength and stiffness (modulus) decrease. What’s the Difference

Yellowing, surface cracks, loss of elasticity, and brittleness. loss of elasticity

: The tube will slightly expand in size and volume as it reaches equilibrium.

If your goal is to prevent the tube from "maturing" into a failed, brittle state, monitor these factors:
