Crystallization Kinetics Study of Impact Polypropylene Copolymer with Kenaf as Nucleating Agent and Reinforcement

Impact Polypropylene Copolymer (IPC) is an material which combines properties of isotactic Polypropylene (iPP) and its own high impact toughness. However, the crystallization kinetics might be lower than iPP, which may affect the manufacturing cycles. Kenaf was used as the addition in IPC, in wh...
