Manufacturing Quality Control of PEEK
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance and Color | Visual Inspection, Colorimeter | Observe the sample surface visually or using instruments to detect defects such as smoothness, impurities, bubbles, or discoloration; colorimeter quantitatively evaluates color consistency. |
| Melting Point | Differential Scanning Calorimetry (DSC) | Measure the melting temperature of PEEK during heating to assess purity and crystallinity; typical melting point is approximately 343°C. |
| Thermal Stability | Thermogravimetric Analysis (TGA) | Measure mass change of the sample under programmed heating to evaluate decomposition temperature (typically initial decomposition temperature >500°C), assessing thermal stability. |
| Crystallinity | DSC, X-ray Diffraction (XRD) | DSC calculates crystallinity from melting enthalpy; XRD analyzes crystal structure peak intensities to assess material crystallinity. |
| Molecular Weight and Molecular Weight Distribution | Gel Permeation Chromatography (GPC) | Dissolve the sample in solvents such as tetrahydrofuran to determine number-average molecular weight (Mn), weight-average molecular weight (Mw), and polydispersity index (PDI). |
| Chemical Structure | Fourier Transform Infrared Spectroscopy (FTIR) | Analyze characteristic functional group absorption peaks (e.g., C=O, aromatic rings, ether bonds) to confirm whether the PEEK chemical structure conforms to specifications. |
| Mechanical Properties | Tensile Test, Flexural Test, Impact Test | Test tensile strength, elongation at break, flexural modulus, and notched impact strength according to ASTM or ISO standards to evaluate mechanical performance. |
| Density | Density Gradient Column Method, Liquid Pycnometry | Determine material density using density gradient tubes or immersion methods (PEEK density is approximately 1.30–1.32 g/cm³) for quality consistency control. |
| Moisture Content | Karl Fischer Titration | Precisely measure trace moisture content in raw materials or finished products to prevent degradation during processing due to water. |
| Residual Monomers and Impurities | High-Performance Liquid Chromatography (HPLC) or GC-MS | Detect unreacted monomers (e.g., hydroquinone, 4,4'-difluorobenzophenone) and other organic impurities. |
| Ash Content | Residue on Ignition (Muffle Furnace) | Incinerate the sample at high temperature (e.g., 850°C) to determine the content of inorganic residues, reflecting filler or additive residues. |
| Extractables | Solvent Extraction + Gravimetric or Chromatographic Analysis | Extract soluble substances using simulated body fluids or organic solvents to evaluate biocompatibility or processing stability. |
| Surface Elemental Composition | X-ray Photoelectron Spectroscopy (XPS) | Analyze the types and chemical states of elements on the material surface, used for surface modification or contamination detection. |
| Microstructure | Scanning Electron Microscopy (SEM) | Observe fracture surfaces or microstructures to assess cracks, porosity, and uniformity of filler dispersion. |
