Study on the Reflecting Properties of HFHIPS

Abstract

With HFHIPS as the substrate, through the double-screw extrusion processing technology of blending modification, add the titanium dioxide (TiO2) and brightener (ZB) into the HFHIPS. Change the content of TiO2 and ZB of the substrate respectively, study the influence of content on the HFHIPS Reflective materials with microstructure on surface, Including reflectivity, whiteness, impact strength and tensile strength. The results show that, when add the TiO2 and ZB into the HFHIPS, reflectivity and whiteness were improved obviously. Reflectivity can reach 95.3%, at the same time, the intensity will not have a significant reduction; But when the content reaches a certain value, TiO2 and ZB will cover each other, this will reduce the reflectivity and whiteness.
