HDPE resin for large container blow molding
Blow-molding HDPE, MI < 0.35 g/10 min · jerrycans, drums, large containers
Jerrycans, drums and large containers need resin with high melt strength so the parison does not sag during blowing and the walls stay thick and impact-resistant. Choose blow-molding HDPE with a low melt index, below 0.35 g/10 min (190 °C/2.16 kg).
Quick rule: MI < 0.35 → large jerrycans, drums, containers · MI ≥ 0.35 → small jerrycans, bottles, vials. See resin for small containers & bottles →

FAQ
Which resin is used for blow molding large jerrycans and drums?
Blow-molding HDPE with a melt index (190 °C/2.16 kg) below 0.35 g/10 min, e.g. HD-B4809, YUZEX 2600Y, 5502S, HD03550, HD03580, HHM5502LW. The lower the MI, the higher the melt strength and the larger the part it suits.
What MI is used for large vs small containers?
Thien An quick rule: MI below 0.35 → large jerrycans, drums and containers; MI 0.35 or higher → small jerrycans, bottles and vials. Borderline grades such as HHM5502LW (0.34) work for both.
