The water-absorbing speeds of nylon resins at 23°C in
water are compared in Figure 5. The water-absorbing speed of nanocomposite
M1030DH is quite smaller than that of a regular nylon A1030JR, and
thus M1030DH is more stable to water.
|| <Water Absorption and Dimensional
The relationship between the water absorption
and the dimensional change is shown in Figure 6. M1030DH resin exhibits
a small dimensional change by absorbing water, much smaller than
an inorganic-fillered nylon A3130. Nonocomposite nylon resins are
excellent in dimensional stability.
