Manufacturing Quality Control of POLYSULFONE
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance and Color | Visual Inspection / Colorimeter Method | Observe whether resin particles are uniform and free of impurities or discoloration; use a colorimeter to quantitatively assess color deviation. |
| Melt Flow Rate (MFR) | Melt Flow Indexer Method (ASTM D1238) | Measure the mass of molten resin passing through a standard die per unit time under specified temperature (e.g., 330–375°C) and load, to evaluate processability and flow behavior. |
| Number-Average Molecular Weight (Mn) and Weight-Average Molecular Weight (Mw) | Gel Permeation Chromatography (GPC/SEC) | Dissolve the sample in solvents such as tetrahydrofuran, then analyze molecular weight distribution via gel permeation chromatography to assess polymer consistency. |
| Thermal Properties (Glass Transition Temperature Tg) | Differential Scanning Calorimetry (DSC, ASTM E794) | Determine the glass transition temperature during heating to evaluate thermal stability and structural homogeneity. |
| Thermal Stability and Decomposition Temperature | Thermogravimetric Analysis (TGA, ASTM E1131) | Measure changes in sample mass as a function of temperature under programmed heating to determine initial decomposition temperature and weight loss behavior, assessing heat resistance. |
| Moisture Content | Karl Fischer Titration | Precisely determine trace moisture content in resin to prevent degradation or bubble formation during processing. |
| Infrared Spectroscopy (Functional Group Analysis) | Fourier Transform Infrared Spectroscopy (FTIR) | Analyze characteristic absorption peaks to confirm correct chemical structure and detect impurities or oxidation products. |
| Solubility | Solvent Dissolution Test | Dissolve the resin in specific solvents (e.g., dichloromethane, NMP) and observe dissolution rate and clarity to assess purity and batch consistency. |
| Ash Content | High-Temperature Combustion Method (ASTM D2584) | Burn off organic components in a high-temperature muffle furnace; weigh the residual inorganic material to calculate ash content and evaluate inorganic impurity levels. |
| Density | Density Gradient Column Method / Pycnometer Method | Measure mass per unit volume to assess material composition consistency and detect issues such as uneven filler distribution. |
