| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and physical form (typically light yellow to amber powder or granules), checking for uniformity and presence of impurities. |
| Melting Point | Capillary Melting Point Method | Determine the melting temperature range using a digital melting point apparatus or traditional capillary method to assess purity (typical value approximately 98–102°C). |
| Loss on Drying | Gravimetric Method (Oven Drying) | Weigh a sample and dry it under specified conditions (e.g., 75±2°C) and vacuum for a defined period, then calculate the percentage weight loss. |
| Residue on Ignition (Ash Content) | High-Temperature Ignition Method | Burn the sample in a muffle furnace at high temperature (e.g., 800°C) until constant weight is achieved; the remaining ash content indicates levels of inorganic impurities. |
| Residue on Sieve | Standard Sieving Method | Sieve a known quantity of sample through a standard mesh sieve (e.g., 60 mesh or 150μm); calculate the percentage of material retained on the sieve to evaluate particle fineness. |
| Initial and Final Melting Points | Differential Scanning Calorimetry (DSC) | Determine precise melting onset and end temperatures from the DSC curve for substance identification and assessment of crystalline purity. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reverse-phase C18 column with UV detection (e.g., 254 nm) and external standard method to quantify the main component (typically required ≥97.0%). |
| Impurity Analysis | HPLC or GC-MS | Separate components via chromatography and identify/quantify major organic impurities (e.g., unreacted raw materials, by-products) using mass spectrometry. |
| pH Value (Aqueous Suspension) | pH Meter Measurement | Disperse the sample in water, allow to settle, and measure the pH of the supernatant to evaluate acidity or alkalinity (generally required to be neutral or slightly alkaline). |
| Specific Surface Area / Particle Size Distribution | Laser Particle Size Analyzer / BET Method | Used to evaluate the impact of physical properties on rubber processing performance, particularly important for pre-dispersed masterbatch applications. |
