      Leaching.

AB  - Leather waste (BF) and high-density polyethylene (HDPE) were compounded in a lab 
      scale internal mixer and processed by means of injection molding. In this study, 
      leather waste and HDPE composites were characterized by instrumental techniques 
      such as differential scanning calorimetry (DSC), thermo-gravimetric Analysis 
      (TGA), and Fourier transform infrared spectroscopy (FTIR). Physical integrity of 
      composites against chemical exposure and chromium-leaching properties of the 
      composites were also investigated. This study shows that the incorporation of 30% 
      leather waste fiber into HDPE composites decreases the thermal conductivity of 
      the composite samples by 17% in comparison to that of neat HDPE samples. 
      Composites showed no thermal degradation during processing cycle. Strong 
      interfacial bonding between leather waste and polymer results in comparable 
      low-leachate levels to maximum allowed concentration for nonhazardous waste, and 
      good chemical resistance properties. The BF/HDPE composites could be a promising 
      low-cost alternative in industrial application areas of HDPE, where 
      high-mechanical strength and low-thermal conductivity is required.
