PEKK — Polyetherketoneketone (PEKK) Pellets Supplier China | Aerospace / Oil & Gas Grade
PEKK (Polyetherketoneketone, 聚醚酮酮) is a next-generation polyaryletherketone with higher glass transition temperature (Tg = 158-165°C) vs PEEK's 143°C, enabling higher continuous service temperature.
Key Properties of PEKK vs PEEK
| Property | PEEK | PEKK | Notes |
|---|
| **Glass transition (Tg**) | 143°C | **158-165°C** | PEKK +15-22°C |
|---|---|---|---|
| **Continuous service temp** | 260°C | **280°C** | PEKK +20°C |
| **Tensile strength** | 90-100 MPa | **100-110 MPa** | PEKK higher |
| **Chemical resistance** | Excellent | **Excellent** | Comparable |
| **Glass-filled HDT** | 315°C | **335°C** | PEKK higher |
| **Cost** | $$$ | $$ | PEKK premium |
