The density of PEEK (Polyether Ether Ketone) typically ranges from 1.26 to 1.72 g/cm³, depending on the grade and additives used. For unfilled pure PEEK resin, the standard density is 1.31–1.32 g/cm³. This critical property directly impacts your part's weight, strength-to-weight ratio, and performance in demanding applications like aerospace, medical implants, and automotive components.

As a top-tier SEO content strategist and industry expert with years of experience in high-performance plastics, I've helped countless manufacturers optimize their material selection. Here's what makes Dongguan PRES Group Co., Ltd. your ideal OEM partner for PEEK products in China.
| PEEK Grade Type | Density (g/cm³) | Key Characteristics |
|---|---|---|
| Unfilled Pure PEEK | 1.31–1.32 | Standard grade, excellent chemical resistance mcam+1 |
| Amorphous PEEK | 1.26 | Lower crystallinity state pmc.ncbi.nlm.nih+1 |
| Fully Crystalline PEEK | ~1.40 | Maximum density at full crystallization pmc.ncbi.nlm.nih |
| PEEK Range (General) | 1.26–1.32 | Most common unfilled grades specialchem+1 |
| Carbon Fiber Reinforced | 1.40–1.54 | Higher strength, 3.5× thermal conductivity sciencedirect+1 |
| Glass Fiber Reinforced | 1.49–1.54 | Improved stiffness, heat resistance specialchem |
| Wide Grade Range | 1.26–1.72 | Including all specialized grades peekchina |
Key Insight: The density of PEEK depends on the amorphous/crystalline phase ratio. Fully amorphous PEEK has a density around 1.26 g/cm³, while fully crystalline PEEK reaches approximately 1.40 g/cm³. [pmc.ncbi.nlm.nih]
PEEK's density of 1.32 g/cm³ is roughly 8× lighter than steel (7.8 g/cm³) while maintaining exceptional mechanical strength. This makes it ideal for replacing metal components in aircraft, reducing weight and fuel consumption. [en.wikipedia]
PEEK's density and modulus are similar to human bone, making it perfect for 3D-printed orthopedic implants. The material promotes bone growth without the stress-shielding issues seen with metal implants. [peekchina]
PEEK maintains stability across a wide temperature range (-100°C to +260°C) with minimal expansion. Its low coefficient of linear thermal expansion (CLTE) ensures parts don't deform in hot water or steam environments. [ensingerplastics]

For PEEK 3D printing filament, density impacts:
- Print weight calculations for cost estimation
- Layer adhesion (semi-crystalline structure requires heated chamber at 120°C) [jlc3dp]
- Final part density (Orion AM's TRH process achieves 99.97% density in printed parts) [orion-am]
| Requirement | Specification | Purpose |
|---|---|---|
| Nozzle Temperature | 360–450°C | Melting PEEK properly jlc3dp |
| Heated Bed | 120–160°C | Prevent warping jlc3dp |
| Chamber Temperature | 70–150°C (ideally 120°C) | Ensure layer bonding jlc3dp |
| Filament Drying | 120°C for 3–6 hours | Remove moisture (PEEK is hygroscopic) jlc3dp |

| Material | Density (g/cm³) | Continuous Use Temp | Key Advantage |
|---|---|---|---|
| PEEK (unfilled) | 1.31–1.32 | 250–260°C peekchina | Best strength + chemical resistance tuntunplastic |
| PEK | ~1.35 | Higher than PEEK | Superior thermal stability gtweed |
| PTFE (Teflon) | ~2.20 | 260°C | Better electrical insulation tuntunplastic |
| Nylon | 1.15–1.17 | <100°C rapid-protos | Lower cost, high impact toughness rapid-protos |
| ULTEM (PEI) | ~1.27 | 217°C | Lower density, good clarity 3dnatives |
Expert Verdict: PEEK outstrips ULTEM in mechanical strength while maintaining a competitive density. For applications requiring strength and low deformation, choose PEEK over PTFE. [tuntunplastic]
