HDPE for crates, pails, caps and closures, housewares and totes. Tell us the melt index and density you run now, and whether stress-crack resistance matters, and we’ll match it.
Get a quote on HDPEInjection-molding HDPE is chosen mainly by melt index (190°C / 2.16 kg) and density. Higher MI fills thin walls and long flow paths faster; lower MI and bimodal grades give more toughness and better environmental stress-crack resistance (ESCR), which matters for closures and anything that holds detergents or chemicals. Higher density adds stiffness.

|---|---|
| Density | ~0.950–0.965 g/cm³ |
| Impact strength | Good, including cold |
| Chemical resistance | Excellent |
| ESCR | Varies widely by grade |
| Relative cost | Low |
