Abstract: Discussing the mould shrinkage influence of different fillings, different content and POE, PE modified materials and nucleating agent, the results show that significant improvement compared with both filler composite shrinkage, in which glass fiber the most remarkable improvement, with the filler and shrinkage increase the amount of fill decreases, adding nucleating agents also can improve the mould shrinkage.
