PEEK typically costs $60–90 per kg for virgin resin from Chinese manufacturers, $100–200 per kg for Western-branded resin (Victrex, Solvay, Evonik), and $150–400 per kg once converted into sheets, rods or filament. Medical and implantable grades run far higher — often $300–500 per kg. But the real question is never the sticker price: it is which form, grade and quantity fits your part. Here is the complete 2026 PEEK price picture:
PEEK polyether ether ketone price varies enormously by form of supply. The closer the material gets to a finished shape, the more processing value — and price per kg — is built in:
| Supply Form | Typical Price Range (USD/kg) | What You Are Paying For |
|---|---|---|
| Virgin PEEK pellets (China, unfilled) | $60–90 | Base resin only — for injection molding, extrusion, filament drawing |
| Virgin PEEK resin (Western brands) | $100–200 | Brand premium, batch consistency, global technical support |
| CF/GF filled PEEK pellets | $85–150 | Compounding line time — carbon fiber grades sit at the top of the range |
| PEEK sheet (unfilled) | $150–280 | Extrusion or compression molding + annealing + cutting losses |
| PEEK rod / tube | $170–320 | Lower output speed than sheet, higher scrap rate on small diameters |
| PEEK 3D printing filament | $280–600 | Tight diameter tolerance (±0.02mm), spooling, drying and packaging |
| PEEK powder (coating / sintering grade) | $90–160 | Sieving to narrow mesh bands (50–1000 mesh) adds yield loss |
| Medical / implantable grade | $300–500+ | ISO 10993 biocompatibility testing, cleanroom handling, full traceability |
A common reaction to the first PEEK quotation is "this is just plastic — why does it cost 100× more than PP?" The short version: 75% of production cost is raw material — chiefly the fluorinated monomer DFBP (0.7–0.8 tons per ton of PEEK, at ≥99.99% purity) — followed by polymerization at 280–340°C in specialty solvent, low batch yields, certification costs and a supplier oligopoly. We break down the full fluorine chemistry and process economics in a dedicated article: Why Is PEEK Plastic So Expensive?
"PEEK" is not one product. Modification changes both performance and price — and counter-intuitively, adding fillers usually lowers cost per kg while raising stiffness:
| Grade | Relative Price vs Virgin | When the Premium Makes Sense |
|---|---|---|
| Unfilled / virgin PEEK | Baseline (100%) | Maximum toughness and elongation, best for bearings seats, seals, medical |
| 30% glass filled (GF30) | ~90–100% (often cheaper per kg) | Structural parts needing stiffness and dimensional stability — filler dilutes resin cost |
| 30% carbon filled (CF30) | ~110–140% | Highest stiffness-to-weight, ESD protection, sliding wear parts |
| ESD / anti-static grades | ~120–150% | Semiconductor handling, wafer carriers, cleanroom tooling |
| Medical / implant grade | ~300–500% | Only where regulatory compliance demands it — never over-specify |
Before committing to PEEK, check whether a cheaper high-performance plastic already meets your temperature and load requirements. This comparison is where most material cost savings are found:
| Material | Approx. Cost vs PEEK | Continuous Use Temp | Choose It When |
|---|---|---|---|
| PEEK | Baseline | 260°C | Nothing else survives the environment |
| PPSU | ~60–80% | 180°C | Repeated steam sterilization, extreme toughness, BPA-free food contact |
| PEI (ULTEM) | ~50–65% | 170°C | Precision electrical parts, dimensional stability at moderate heat |
| PPS | ~25–35% | 200–240°C | Chemical exposure, EV high-voltage parts, under-hood components |
| PTFE | ~15–25% | 260°C | Pure chemical inertness and lowest friction — but soft and creep-prone |
| PA66 (GF30) | ~5–8% | 100–120°C | General structural parts where temperature never exceeds ~120°C |
The engineering question behind every PEEK quotation: does your part truly need 260°C continuous service, fatigue resistance at the top of the thermoplastic class and near-universal chemical resistance? If it needs two of the three, PEI or PPS may deliver the required performance at half (or a quarter) of the PEEK plastic price. If it needs all three — PEEK is usually the only answer, and its price is justified by the cost of failure.
Two buyers ordering the same polymer on the same week can receive quotes differing by 40%. These are the levers:
Order volume — the single biggest factor. Full-lot pellet orders (500kg+) can come in 20–30% below small-lot pricing.
Form factor — pellets < powder < film < sheet < rod < filament, in rising order of processing cost per kg.
Grade and modification — as tabled above: GF30 ≈ virgin < CF30 < ESD < medical.
Viscosity selection — high-viscosity extrusion grades and low-viscosity injection grades are priced differently; using the wrong one for your process wastes money twice.
Documentation requirements — FDA/USP Class VI/NORSOK declarations, batch CoAs and traceability each add cost; order them only when your industry requires them.
Brand vs China direct — Western-branded resin carries a 40–100% premium over Chinese virgin resin of equivalent specification. For most industrial parts, Chinese-made PEEK now meets the same application requirements.
Supply chain distance — buying from a manufacturer that also does extrusion, cutting and machining removes one or two middlemen margins from semi-finished products.
Down-spec deliberately. Run a material selection review against real service conditions — many parts specified in medical-grade PEEK perform identically in industrial grade at 60% lower price.
Switch to filled grades where possible. GF30 for stiffness-critical parts, CF30 for stiffness + ESD. Both dilute the expensive resin phase.
Buy near-net-size blanks. Ordering a 100mm rod to machine a 30mm part means paying for 89% waste. Cut-to-size stock reduces material cost per finished part dramatically.
Use injection molding instead of machining for volume. Above roughly 500–1,000 pieces, mold amortization beats CNC hours, and pellet feedstock is 2–3× cheaper per kg than rod or sheet.
Consolidate grades. Using one viscosity grade across several parts simplifies inventory and earns volume-tier pricing on a single SKU instead of fragmenting orders across three.
Buy from the source. A manufacturer that controls pellet compounding through semi-finished extrusion can quote both lines competitively — and take responsibility for material consistency across the chain.
