HDPE Formosa Plastics 8003
HDPE Formosa Plastics 8003 Resin
Material Introduction: HDPE Formosa Plastics 8003 is a high‑density polyethylene grade. With high rigidity, good chemical resistance and excellent environmental stress‑cracking resistance, it is widely used for containers and packaging requiring sufficient strength and durability.
Main Applications
Food & pharmaceutical containers: food vessels, fresh‑milk bottles, pharmaceutical cans. Non‑toxic, tasteless and odorless, compliant with FDA 21 CFR 177.1520 for food‑contact and pharmaceutical packaging.
Industrial containers & toolboxes: toolboxes and general‑purpose industrial containers.
Performance Parameters
| Performance Category | Test Item | Test Method / Condition | Value & Unit | Remarks & Interpretation |
|---|---|---|---|---|
| Basic Properties | Density | ASTM D‑1505 | 0.958 g/cm³ | HDPE grade with high hardness and good rigidity. |
| Melt Flow Rate (MFR) | ASTM D‑1238 (190°C/2.16 kg) | 0.25 g/10min | Low MFR brings good melt strength, ideal for hollow blow molding to maintain product geometry. | |
| Mechanical Properties | Tensile Yield Strength | ASTM D‑638 | 300‑310 kg/cm² (≈29.4‑30.4 MPa) | High value represents good tensile‑deformation resistance and rigidity. |
| Tensile Strength at Break | ASTM D‑638 | 320‑380 kg/cm² (≈31.4‑37.3 MPa) | Maximum stress before fracture; slight deviation among different data sources. | |
| Elongation at Break | ASTM D‑638 | 1000 % | Superb toughness and ductility; withstand heavy deformation without fracture. | |
| Izod Notched Impact Strength | ASTM D‑256 | 25 kg·cm/cm | Indicator of impact‑resistance performance. | |
| Hardness | ASTM D‑2240 | 69 Shore D | Provides certain surface scratch‑resistance. | |
| Environmental Stress‑Cracking Resistance (ESCR) | ASTM D‑1693 | 30 Hours | Anti‑stress‑cracking performance under specified chemical environment; higher value preferred. | |
| Thermal Properties | Melting Point | FPC method | 134 ℃ | Reference for processing‑temperature setting. |
| Vicat Softening Temperature | ASTM D‑1525 | 127 ℃ | Heat‑resistance indicator. | |
| Brittleness Temperature | ASTM D‑746 | ＜‑70 ℃ | Retain toughness under ultra‑low temperature with excellent low‑temperature performance. |
Injection‑Molding Process Parameters
| Process Parameters | Recommended Range | Remarks & Interpretation |
|---|---|---|
| Drying Treatment | Normally not required | No drying needed under proper storage. |
| Melt Temperature | 200‑260℃ | For high‑molecular‑weight grades, adopt 200‑250℃. |
| Mold Temperature | 50‑95℃ | Higher mold temperature for wall thickness below 6 mm; lower mold temperature for wall thickness above 6 mm. Uniform cooling reduces shrinkage deviation. |
| Injection Pressure | 700‑1050 bar | ‑ |
| Injection Speed | High‑speed injection recommended | ‑ |
| Runner & Gate | Runner diameter 4‑7.5 mm | Keep runner length as short as possible. Various gate types are acceptable; gate length ≤0.75 mm. Hot‑runner molds are well‑suited. |
