<Flowability>
The flowability of M1030DH and A1030JR resins during bar-flow molding (thickness: 1mm) is shown in Figure 9. The flowability of M1030DH is larger than that of A1030JR.
  <Recycling Property>
The change in tensile properties of the resins after 100% recycling is shown in Figure 10 (resin temperature: 250°C). The nanocomposite resin does not exhibit any decrease in strength even after 5 repeated complete recycling, but allows slight increase in elongation.

Figure 9. Flowability (Bar flow, thickness: 1 mm) Figure 10. Recycling property (100% recycling)
<Molding Shrinkage>
In Figures 11 and 12, shown are the molding shrinkages of resins, as determined by using a rectangular molded plate with a film gate of 50x50 mm in dimension. The molding shrinkage of the plates from the M1030DH resin is similar to that of a general nylon 6 A1030JR, but the nanocomposite plates have some anisotropy. In addition, the effect of the mold temperature on the molding shrinkage of M1030DH is characteristically smaller than on that of A1030JR.
