Industrial Applications of Uvinul 4050 H
| Industry | Application | Processing Method |
|---|---|---|
| Plastics Industry | Enhances UV light aging resistance of polyolefin materials | Added during extrusion or injection molding of polymers such as polyethylene and polypropylene to improve UV stability of end products exposed to outdoor conditions |
| Coatings Industry | Prevents yellowing and degradation of coatings caused by UV exposure | Incorporated into solvent-based or water-based coating formulations; forms a UV-protective layer during film formation |
| Fibers Industry | Improves weather resistance of synthetic fibers | Mixed with polymer melt prior to spinning; processed via spinning to produce fibers with long-term light stability |
| Agricultural Film Manufacturing | Extends service life of agricultural films under solar exposure | Added during blown film or cast film production to enhance UV resistance of polyethylene agricultural films |
Manufacturing Quality Control of Uvinul 4050 H
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 290-310 nm based on peak area comparison against reference standard. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine generated electrochemically or added stoichiometrically in methanol-based reagent. |
| Ash Content | Gravimetric Analysis (Incineration) | Measures inorganic residue after high-temperature incineration (550-600 C) and subsequent weighing of the cooled crucible. |
| Heavy Metals (as Pb) | ICP-OES | Quantifies total heavy metals by plasma excitation and optical emission spectroscopy after acid digestion and dilution. |
| Residue on Ignition | Gravimetric Analysis (Incineration) | Measures non-volatile impurities remaining after heating sample to 700-750 C until constant weight is achieved. |
| Acid Value | Acid-Base Titration | Determines free carboxylic acid groups by titration with standardized KOH solution using phenolphthalein indicator. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid using calibrated capillary tube and controlled heating rate. |
| Color (APHA) | Visual Comparison or Spectrophotometric Method | Evaluates yellowness intensity by comparing sample solution color to APHA platinum-cobalt standard solutions or measuring absorbance at 430 nm. |
| Volatile Matter | Thermogravimetric Analysis (TGA) | Determines weight loss under controlled nitrogen atmosphere from 25 C to 150 C, indicating low-boiling impurities or solvents. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dry powder using Mie scattering theory applied to laser light diffraction patterns. |
| Organic Volatile Impurities (e.g., toluene, xylene) | GC-FID | Identifies and quantifies residual solvents by gas chromatography separation followed by flame ionization detection. |
| Sulfated Ash | Gravimetric Analysis (Sulfuric Acid Ashing) | Measures ash content after wet ashing with sulfuric acid and subsequent high-temperature incineration to convert metals to sulfates. |
