Optimal state for standard operation in pneumatic or fluid systems.
: While toughness increases, the absolute tensile strength and stiffness (modulus) decrease. nylon matures tube
: Depending on wall thickness and humidity, reaching a stable "mature" state can take anywhere from days to several weeks . 2. Guide to Managing Nylon Tubing Life Cycles Characteristics Recommendations Initial (DAM) High stiffness, low impact resistance, maximum brittleness. Avoid high-impact installation immediately after extrusion. Mature (Conditioned) Balanced strength and flexibility; dimensions are stable. Optimal state for standard operation in pneumatic or
Yellowing, surface cracks, loss of elasticity, and brittleness. Mature (Conditioned) Balanced strength and flexibility
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:
: The tube will slightly expand in size and volume as it reaches equilibrium.
