Fig.1 The effect of CMG9801 on notched impact strength of PP+30%GF system
Fig.1 shows that the notched impact strength was obviously improved with the addition of CMG9801. The impact strength reaches a maximum when the content is 3%.
Fig.2 The SEM graph of PP+30%GF system without and with 3% CMG9801
As shown in fig.2, the compatibility between PP matrix and GF was obviously enhanced with the introduction of CMG9801, this is essential to obtain high mechanical performance, and for the final products the phenomenon of “glass emergence” can also be improved.
Case 2: The effect of CMG9801 on the long-term heat aging properties of PP+30%GF system
Fig.3 The effect of CMG9801 on the long-term heat aging properties of PP+30%GF system
As shown in fig.3, the samples added CMG9801 have a much better long-term heat aging properties than domestic products, especially when the aging time longer than 900h. And the CMG9801 still have advantages compared with the imported product.
