Nylon Matures Tube -

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:

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

While there is no standard engineering term "nylon matures tube," the phrase typically refers to the or the natural aging (maturation) of nylon tubing. Nylon is unique because it is hygroscopic, meaning it absorbs moisture from the air after manufacturing, which significantly changes its mechanical properties—a process often called "maturation" or "conditioning." 1. The Maturation (Conditioning) Process Freshly extruded nylon tubing is "Dry As Molded"

: Impact resistance can improve by up to 10 times as the material absorbs water. Nylon is unique because it is hygroscopic, meaning

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