Industrial Applications of UV-144
| Industry | Application | Processing |
|---|---|---|
| Plastics Industry | Light stabilizer for polyolefin products (e.g., PP, PE), preventing UV-induced degradation, discoloration, and loss of mechanical properties | Added by dry blending with resin and other additives prior to extrusion pelletizing or injection molding; typical dosage: 0.1–0.5 wt% |
| Coatings Industry | Light stabilizing component for outdoor solvent-based and high-solids acrylic/polyurethane coatings, enhancing film weatherability | Added during the final dispersion stage or let-down phase; avoid prolonged exposure to elevated temperatures; recommended dosage: 0.3–1.0 wt% (based on total formulation) |
| Synthetic Fibers | Light stabilizer for polyester (PET) and polyamide (PA) during melt spinning and subsequent finishing processes | Blended with polymer chips prior to melt spinning or incorporated as a masterbatch; alternatively, applied via fiber post-treatment impregnation baths; dosage: 0.2–0.8 wt% (based on fiber weight) |
| Agricultural Films | Long-term light stabilizing component for LDPE/LLDPE agricultural mulch films, delaying embrittlement and loss of light transmission caused by UV aging | Used synergistically with antioxidants (e.g., Irganox 1010) and UV absorbers (e.g., UV-531); dry blended prior to blown-film extrusion; typical dosage: 0.25–0.4 wt% |
Manufacturing Quality Control of UV-144
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (LS-144 content) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 340 nm. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of visible particles or phase separation under controlled lighting and temperature. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, following ASTM D1565 or ISO 4625. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration with iodine reagent to quantify water content based on stoichiometric reaction with iodine and sulfur dioxide. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measurement of non-volatile inorganic residue after high-temperature ashing at 750 C in a muffle furnace. |
| Heavy Metals (Pb, Cd, Hg, Cr) | ICP-OES | Multi-element quantification by measuring atomic emission intensities of plasma-excited elements after acid digestion. |
| Chlorinated Hydrocarbon Impurities | GC-ECD | Separation and selective detection of chlorinated compounds using electron capture detection after capillary gas chromatography. |
| Acid Value | Acid-Base Titration | Neutralization of acidic functional groups with standardized KOH solution using phenolphthalein indicator. |
| UV Absorption Spectrum | UV-Vis Spectrophotometry | Verification of characteristic absorption maxima and spectral profile in ethanol solution against reference spectrum. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered light intensity patterns to determine volume-based particle size distribution in suspension. |
| Bulk Density | ASTM D1895 Method A | Measurement of mass per unit volume for freely settled powder using a calibrated cylinder and balance. |
| Volatile Organic Impurities | Headspace GC-FID | Quantification of residual solvents and low-boiling impurities via gas chromatography with flame ionization detection. |
