HDPE Huajin Chemical T5070
HDPE Huajin Chemical T5070 Resin
Material Introduction: HDPE Huajin Chemical T5070 is a typical injection‑molding grade. Its medium melt flow rate and relatively high density make it well‑suited for medium‑to‑large‑size containers and turnover boxes. Good rigidity, impact resistance and chemical resistance satisfy fundamental performance requirements of such applications.
Main Applications
Logistics containers: fish boxes, crates, turnover boxes, pallets.
Industrial containers: large‑size industrial parts, shipping and turnover bins.
Daily‑use articles: hand‑held cases and household goods.

Processing Parameters
| Processing Parameters | Recommended Range | Remarks |
|---|---|---|
| Barrel Temperature (Rear) | 160‑180℃ | Feeding zone, prevent material bridging |
| Barrel Temperature (Middle) | 180‑220℃ | Compression zone, preliminary melting |
| Barrel Temperature (Front) | 200‑240℃ | Metering zone, melt homogenization |
| Nozzle Temperature | 200‑240℃ | ‑ |
| Mold Temperature | 30‑60℃ | Affect cooling rate, crystallinity and surface finish |
| Injection Pressure | 50‑100 MPa | Adjust according to part complexity and wall thickness |
| Holding Pressure | 50%‑80% of injection pressure | Reduce shrinkage and sink marks |
| Screw Speed | 50‑100 rpm | Avoid excessive shear heat |
