In terms of crystallization temperature, the crystallization temperature of PET decreases significantly with the increase of β-nucleating agent addition. In terms of crystallization rate, the crystallization rate of PET increases with the increase of β-nucleating agent addition. In terms of crystallinity, the crystallinity of PET also increases with the increase of β-nucleating agent addition.These results indicate that adding an appropriate amount of β-nucleating agent can significantly improve the crystallization performance of recycled PET, which helps to improve its processing performance and product quality.精品文档---下载后可任意编辑Keywords: β-nucleating agent; PET; crystallization performance; recycling.
