Industrial Applications of Antioxidant 412S
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Thermal stabilizer and antioxidant for polyolefin processing (e.g., PP, PE), preventing high-temperature degradation and oxidative discoloration | Blended with resin prior to extrusion, injection molding, or blow molding; typical dosage: 0.1–0.5 wt% |
| Rubber Industry | Antioxidant for natural rubber (NR) and synthetic rubbers (e.g., SBR), inhibiting thermo-oxidative aging | Added during the compounding stage; used synergistically with antidegradants (e.g., RD, 4020); typical dosage: 0.3–1.0 phr |
| Adhesives & Sealants | Enhances long-term thermal stability and storage stability of acrylic and polyurethane adhesives | Added late in formulation (after cooling to below 80°C) to prevent thermal decomposition; typical dosage: 0.2–0.8 wt% |
| Coatings & Inks | Antioxidant component for polymeric film-formers in clear coats and industrial coatings, retarding yellowing and embrittlement of cured films | Added during grinding or let-down; requires thorough dispersion; recommended dosage: 0.1–0.6 wt% |
Manufacturing Quality Control of Antioxidant 412S
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample in front of a white background and observe its color, state, and uniformity under natural light or standard light sources to determine whether it meets specifications (usually a viscous liquid with a pale yellow to light brown color). |
| Density | Density Meter Method / Pycnometer Method | Use a density meter or pycnometer to measure the mass-to-volume ratio of the sample at a specified temperature (e.g., 25°C), used to assess product consistency. |
| Refractive Index | Abbe Refractometer Method | Measure the refractive index of the sample using an Abbe refractometer under constant temperature conditions (e.g., 20°C or 25°C), serving as an auxiliary indicator for purity and composition. |
| Active Ingredient Content | High-Performance Liquid Chromatography (HPLC) | Use reverse-phase HPLC and compare with a standard reference to quantitatively analyze the main active components (such as hindered phenols) in TH-412S, ensuring compliance with specification requirements. |
| Moisture Content | Karl Fischer Titration | Determine moisture content by measuring the quantitative reaction between the sample and Karl Fischer reagent, using potentiometric titration or coulometric methods for precise measurement, controlling product stability. |
| Acid Value | Acid-Base Titration | Dissolve the sample in an appropriate solvent (e.g., ethanol), then titrate with a standard potassium hydroxide solution to calculate the amount of KOH consumed per gram of sample, reflecting the level of acidic impurities. |
| Ash Content | Residue on Ignition Method | Heat the sample in a high-temperature muffle furnace until constant weight is achieved, then weigh the residual inorganic matter to evaluate the content of inorganic impurities. |
| Thermal Stability | Thermogravimetric Analysis (TGA) | Determine the change in mass of the sample under programmed heating conditions to assess its decomposition temperature and thermal stability, identifying the applicable processing temperature range. |
| Antioxidant Performance | Oxidation Induction Time Test (OIT, DSC) | Determine the time at which oxidation begins (OIT) in an oxygen atmosphere using differential scanning calorimetry (DSC), evaluating the antioxidant capability of the sample. |
| Volatile Matter | Oven Loss Method | Weigh the mass loss of the sample after drying at a specified temperature (e.g., 105°C) for a certain period, assessing the content of volatile components. |
