HDPE Formosa Plastics 8001
HDPE Formosa Plastics 8001 Resin
Material Introduction: HDPE Formosa Plastics 8001 is an extrusion‑grade high‑density polyethylene resin, classified as PE100 pipe‑specialized grade. Featuring excellent pressure‑resistant strength, superior environmental stress‑cracking resistance (ESCR), good creep resistance and chemical corrosion resistance, it is widely used in pressure piping systems.
Main Applications
Water‑supply pipes: PE water‑supply pipes, capable of withstanding internal water pressure and external loads for long‑term reliable service.
Gas‑transportation pipes: PE gas pipes with stringent requirements for safety and pressure resistance.
Industrial & municipal sewage pipes: Sewage and drainage pipes resistant to corrosive media and external pressure.
Chemical pipes: PE chemical pipes with certain chemical‑corrosion resistance.
Protection sleeves: Cable sleeves, TV cable sleeves and other protective conduits.

Processing Parameters
| Processing Stage | Parameters | Recommended Range / Description |
|---|---|---|
| Drying | Necessity | Pre‑drying is normally unnecessary. If moisture is detected under humid storage condition, dry at 60‑80°C for 1‑2 hours to avoid surface defects. |
| Extrusion | Barrel Temperature Profile | Feeding zone:160‑180°C；Compression zone:180‑200°C；Metering zone:200‑220°C；Die‑head & die:210‑230°C |
| Melt Temperature | Recommended:200‑230°C. Avoid excessive temperature and long residence time to prevent material degradation. | |
| Screw Speed | Adjust according to pipe dimension and extruder size for sufficient plasticization and stable extrusion. | |
| Cooling | Sizing & Cooling | Vacuum sizing tank is required. Cooling water tank shall provide sufficient water volume and cooling efficiency. Water temperature:10‑25°C, to guarantee pipe roundness, dimensional stability and lower internal stress. |
| Pulling | Pull‑off Speed | Pull‑off speed shall match extrusion speed stably to achieve uniform wall thickness and straightness of pipes. |
