880CA30 is a 30% carbon fiber reinforced standard flow PEEK pellets. Under the ISO1133 testing standard, the flowability under testing conditions (380 ° C, 5kg) is 5g/10min The use of medium-viscosity Carbon fiber PEEK pellets not only provides excellent mold-filling capability but also satisfies the routine mechanical property requirements of the final parts. Compared to high-flow grades, a moderate melt flow index (MFI) effectively reduces the shear rate during processing, it can reduce carbon fiber damage caused by over-shearing. This helps preserve fiber length and maintain the reinforcement efficiency of the PEEK pellets. This contributes to higher flexural modulus and improved creep resistance in finished parts.
ESD PEEK granules (also known as anti-static PEEK pellets) are carbon-fiber modified compounds engineered for injection molding of semiconductor components. They deliver stable surface resistivity of 10⁶–10⁹ Ω/sq, protecting sensitive circuits from static damage while retaining PEEK's high-temperature strength. Designed for cleanroom environments, these electrostatic dissipative granules offer continuous service at 260°C and excellent chemical resistance. ESD PEEK is the preferred material for test sockets, wafer carriers, and precision gear systems requiring both EMI protection and structural reliability
PEEK 990GF30 is a high-viscosity, 30 % glass fiber reinforced PEEK pellets that delivers substantially higher tensile strength, flexural modulus and improved dimensional stability compared to unfilled PEEK. The high melt viscosity provides stable extrusion behavior and minimizes warpage in thick-section molded parts. With reduced coefficient of thermal expansion (CTE) and good creep resistance at elevated temperature, it is suitable for extrusion of rod, sheet and tube, as well as thick-walled injection molding requiring structural rigidity. Not recommended for thin-wall or long-flow-path injection due to limited melt flow (MFR ≈ 4.5 g/10 min, ISO 1133, 380 ℃/5 kg).
881G is a high purity virgin grade PEEK pellets,It is specifically designed for the production of PEEK 3D printing filaments. It has excellent fluidity.

PEEK pellets :Virgin and reinforced grade,how to choose?
PEEK inherently exhibits a relatively high melt viscosity, which makes melt flow an important criterion when selecting PEEK pellets.
Medium ~high flow grade:Parts with complex geometries, long flow paths, fine details or thin walls,this gradeensure complete filling of the cavity.
Standard-flow or high-viscosity:Part withSimple, thick-walled injection moulded parts, or extrusion applications this grade is more appropriate, as it provides higher melt strength,better toughness and better dimensional stability.
Unfilled Pure PEEK pellets
Unfilled PEEK pellets possess excellent toughness and fatigue resistance. The unfilled PEEK pellets have superior chemical corrosion resistance compared to the fiber-filled PEEK pellets.
High Purity / High Flow PEEK Pellets: Designed specifically for producing 3D printing filaments where melt flow and consistency are paramount.
Electrostatic dissipation(ESD PEEK pellets):By filling carbon fibers and strictly controlling the resistance value, the characteristics of high strength and anti-static are achieved.
The flowability data listed below were measured in accordance with ISO 1133 under test conditions of 380 °C and a 5 kg load, and are provided for reference only.

Resistivity affected by processing
The above parameters are the initial reference values. The actual settings need to be adjusted according to the material type, equipment, mold, part thickness and crystallization requirements. The resistivity of the ESD material should also be verified through actual molded samples.
If you need detailed PEEK particle processing parameters, please refer to the PEEK pellets injection guide. If you need to adjust the surface resistance value of the ESD PEEK injection product, please refer to the ESD PEEK injection guide.

Frequently Asked Questions
Q: What is the difference between CF30 and CA30? A: CF30 denotes the 30% carbon-fiber-reinforced PEEK category. CA30 (e.g., 880CA30, 990CA30) is the PRES internal grade within that category. They refer to the same formulation family.
Q: Is 881G a finished 3D printing filament? A: No. 881G is a high-purity, high-flow PEEK pellet grade designed for extruding 3D printing filament. It is raw material for filament producers, not finished filament.
Q: How do I verify the surface resistivity of ESD PEEK parts? A: Surface resistivity must be measured on the actual injection-molded part using ASTM D257 or IEC 60093. Pellet-level resistivity is not a substitute for post-molding verification, as gate design, screw speed, fill ratio and mold temperature all affect the conductive network.
Q: Where can I download the TDS for each grade? A: TDS PDFs are linked in the grade comparison table above for 880G, 881G, 990G, 880GF30, 990GF30, 880CA30, 990CA30, 880ESD and 990ESD. Bearing-grade TDS is available on request.
