PEEK Fine Powder
PEEK Fine Powder is produced by cryogenic mechanical grinding and air classification of virgin PEEK, yielding a fine powder in the 10 – 100 μm range. With a moderate specific surface area and good flowability, it is engineered for use as a resin matrix in high-performance composites, anti-corrosion coatings and prepreg processes.
Basic Parameters ：
Parameter | Typical Value | Unit | Remarks |
Appearance | White to off-white fine powder | — | No agglomeration, no foreign matter |
Particle Size Range | 10 – 100 | μm |
|
Specific Surface Area | 1.0 – 3.5 | m²/g | By BET method |
Apparent Density | 0.25 – 0.45 | g/cm³ | ISO 60 |
Melting Point (Tm) | 340 – 343 | °C | By DSC method |
Glass Transition (Tg) | 143 | °C | By DSC method |
Melt Flow Rate (MFR) | 10 – 80 | g/10min | 380°C / 5 kg |
Volatiles Content | ≤ 0.5 | % | Affects coating & composite interface quality |
Ash Content | ≤ 0.3 | % | Ignition at 800°C |
Moisture Content | ≤ 0.3 | % | By Karl Fischer titration |
Package | 20 kg / drum | — | Al-foil inner bag + fiber drum |
Features：
● Moderate Specific Surface Area：Good wetting in resin systems
● Narrow Particle Size Distribution (PSD)：Narrow PSD improves coating and composite uniformity
● Low Volatiles & Impurities：Low volatiles & impurities for clean-process applications
● Excellent Dispersibility：Easily dispersed with CF/GF/ceramic fillers
Applications：
● High-performance Composites: CF/GF reinforced PEEK thermoplastic prepregs and compression-molded sheets
● Anti-corrosion & Functional Coatings: Inner-wall coatings for chemical equipment with strong acid and alkali resistance
● Semiconductor & FPD (Flat Panel Display):Wet-process components, electroplating racks, and high-temperature fixtures
● 3D Printing: High-resolution SLS (Selective Laser Sintering) molding
● Inks & Adhesives: High-temperature specialty inks and PEEK-based composite adhesives
