高流动性等规聚丙烯与高密度聚乙烯共混改性

Blending with HDPE Modified the High Fluidity iPP Resin

研究了高密度聚乙烯(HDPE)含量对等规高流动性聚丙烯(iPP)力学性能和流动性能的影响。研究表明,随着HDPE含量的增大,冲击强度越来越大,硬度越来越小。HDPE含量为10%时,拉伸/屈服强度以及弯曲强度出现最大值。共混体系的流动性能随着HDPE含量的增大而减小。

The influence of HDPE content on mechanical properties and flow properties of iPP/HDPE were studied. The results showed that impact strength and hardness of iPP/HDPE blend were improved with the HDPE of content, while flow properties decreased. Tensile/yield strength and bending strength achieved the maximum value when the content of HDPE was 10%.
