Industrial Applications of IRGAFOS P-EPQ
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Long-term thermal stabilizer and antioxidant for polyolefins (e.g., polyethylene, polypropylene) | Added during polymer processing (e.g., extrusion, injection molding) to prevent oxidative degradation under high-temperature processing and extended service life |
| Rubber Industry | Antioxidant protector for synthetic rubbers (e.g., EPDM, SBR) | Incorporated during compounding to enhance durability of rubber products under thermo-oxidative aging conditions |
| Adhesives & Sealants | Improves thermo-oxidative stability of adhesive systems | Used synergistically with other stabilizers in formulations to extend product shelf life and service life |
| Coatings & Inks | Prevents oxidative deterioration of resin binders during storage and film formation | Used as a secondary antioxidant in combination with primary antioxidants (e.g., hindered phenols) |
| Wire & Cable | Stabilizing additive for polyolefin insulation and jacketing materials | Added during cable compound pelletization or extrusion jacketing to ensure long-term operational reliability |
Manufacturing Quality Control of IRGAFOS P-EPQ
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 280 nm. |
| Appearance | Visual Inspection | Assessment of physical state and color by observation under controlled lighting against established visual standards. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, measured by gradual heating of sample in capillary tube. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to quantify water content via stoichiometric reaction. |
| Ash Content | Gravimetric Analysis (Incineration) | Residue mass after high-temperature incineration at 550-600 C, expressed as weight percent of original sample. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption spectroscopy quantifies metal concentration by measuring absorbance of ground-state atoms in flame or graphite furnace. |
| Chloride Content | Potentiometric Titration with AgNO3 | Titration using silver nitrate solution with silver indicator electrode to detect endpoint based on AgCl precipitation. |
| Acid Number | Acid-Base Titration (KOH in ethanol) | Neutralization of acidic impurities with standardized potassium hydroxide solution using phenolphthalein indicator. |
| UV Absorbance (Solution) | UV-Vis Spectrophotometry | Measurement of absorbance at specified wavelength (e.g., 280 nm) in dilute solution to assess chromophore integrity and purity. |
| Residue on Ignition | Gravimetric Analysis (Ignition) | Mass of non-volatile residue remaining after heating at 700-750 C, reported as percentage of initial sample weight. |
| Organic Volatile Impurities | GC-FID | Separation and quantification of volatile organic compounds using gas chromatography with flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity pattern to determine size distribution of dry or dispersed particles. |
