PP Orient Energy S1003 Resin
PP Orient Energy S1003 Resin
Material Introduction: PP Orient Energy S1003 is spinning‑grade homopolymer polypropylene. It features good rigidity, balanced mechanical properties and favorable heat‑resistance, making it an ideal material for various finished products.
Main Applications
Woven products: woven bags for grain, fertilizer and cement packaging, packing straps, ropes, brushes, net‑type products, carpet base fabrics.
Injection‑molded products: automotive interior parts (seat frames, interior panels), home‑appliance housings (computer cases, TV housings), household articles (plastic chairs, tables, storage boxes) and daily‑use goods.
Performance Parameters
| Performance Category | Test Item | Test Condition | Value / Range | Unit | Reference Standard | Remarks & Interpretation |
|---|---|---|---|---|---|---|
| Basic Properties | Melt Flow Rate(MFR) | 230℃/2.16kg | 3.0‑3.4 | g/10 min | ASTM D1238 | Spinning‑grade homopolymer PP. |
| Density | ‑ | 0.90‑0.905 | g/cm³ | ASTM D792, ASTM D1505 | ‑ | |
| Mechanical Properties | Tensile Yield Strength | ‑ | 33.3‑35.3 | MPa | ASTM D638 | ‑ |
| Flexural Modulus | ‑ | 1370‑1470 | MPa | ASTM D790 | ‑ | |
| Elongation at Break | ‑ | ＞200 | % | ASTM D638 | ‑ | |
| Izod Impact Strength | 23℃ | 29‑37 | J/m | ASTM D256 | Room‑temperature impact property. | |
| Rockwell Hardness | R‑scale | 94‑100 | ‑ | ASTM D785 | Surface hardness. | |

Injection‑Molding Process Parameters
| Process Item | Suggested Range / Description | Remarks |
|---|---|---|
| Drying treatment | Generally unnecessary; dry at 80℃ for 1‑2 h under poor storage condition | PP low‑moisture‑absorption feature. |
| Barrel rear zone(feed section) | 160‑200℃ | Prevent thermal degradation. |
| Barrel middle zone(compression section) | 180‑220℃ | ‑ |
| Barrel front zone(metering section) | 200‑240℃ | ‑ |
| Nozzle temperature | 200‑240℃ | ‑ |
| Melt temperature | ‑ | 220‑280℃ |
| Mold temperature | 30‑70℃，recommended 40‑60℃ | Crystallization mainly determined by mold temperature. Low temperature: poor surface, weld‑line and flow‑mark risks; high temperature will cause warpage. |
| Injection pressure | 80‑140 MPa(800‑1400 bar) | Higher pressure available for thin‑wall or complex‑structure parts. |
| Holding pressure | 30%‑60% of injection pressure | Prevent sink mark and excessive shrinkage; holding time accounts for approx. 30% of cycle time. |
| Back pressure | 5‑20 MPa(50‑200 bar) | ‑ |
| Injection speed | Medium injection speed; high‑speed injection required for thin‑wall packaging containers. | ‑ |
| Screw speed | High screw speed(linear velocity 1.3 m/s) is permitted | Complete plasticization before cooling phase finishes. |
| Runner & Gate | Pin‑point gate or multi‑point gate; heated hot‑runner, insulated hot‑runner. Gate shall be set at thick‑wall position of product, otherwise severe shrinkage defect easily occurs. | Mold‑design suggestion. |
