Degradation of Low-density Polyethylene in Kenaf Fiber/Low-density Polyethylene Composite Obtained by Injection Molding Characterized by FT-IR Analysis
Kenaf bast fiber was used to prepare kenaf fiber/linear low-density polyethylene (LLDPE) composite by injection molding technique. Degradation of LLDPE during the processing was investigated using FT-IR analysis. It was observed that slight degradation of pure LLDPE took place after injection molding. It was also found that the extent of degradation of LLDPE became higher when kenaf fiber was used as the filler for LLDPE composite. The addition of kenaf fiber would cause higher shear stress on LLDPE during processing, resulting in higher extent degradation of LLDPE.
