AB  - Phosphogypsum (PG) is one of solid wastes with large amount of yield and serious 
      pollution, which has attracted wide attention. The aim of this study is to 
      investigate filling performance of PG on polypropylene (PP) or high-density 
      polyethylene (HDPE) matrix. In this work, PG was calcined initially to improve 
      whiteness and fix impurities. X-ray diffraction (XRD) results showed that after 
      calcined at 500  degrees C, the PG phase changed from CaSO(4).2H(2)O to CaSO(4). The 
      modification effects of the three modifiers were evaluated by Fourier transform 
      infrared spectra (FTIR), oil absorption value, water floatability, and contact 
      angle analysis. The effects of weight fraction of PG in PP and HDPE matrix on 
      mechanics and morphology were observed by tensile test, impact test, and scanning 
      electron microscope. Scanning electron microscope (SEM) showed that modified PG 
      can be dispersed uniformly in the matrix at low filling content. With the 
      increase of PG filling content, the analysis of mechanical properties showed that 
      the tensile strength of HDPE matrix increased, while the tensile strength of PP 
      matrix decreased gradually. The impact strength of HDPE matrix would decrease, 
      but the impact strength of PP matrix increased first and then decreased. Compared 
      with calcium carbonate (CC), the mechanical properties of HDPE filled with PG 
      performed better. The apparent density showed that polymer composites filled with 
      PG have the characteristics of light weight.
