Industrial Applications of Light Stabilizer 622
| Industry | Application | Processing |
|---|---|---|
| Plastics Industry | Light stabilizer for polyolefins (e.g., PP, PE), preventing UV-induced degradation, discoloration, and loss of mechanical properties | Blended with resin prior to extrusion pelletizing or injection molding; typical dosage: 0.1–0.5 wt% |
| Agricultural Films | Extends outdoor service life of polyethylene (PE) and ethylene-vinyl acetate (EVA) mulch films by inhibiting UV aging-induced embrittlement and cracking | Melt-blended with resin prior to blown film production; commonly used synergistically with other light stabilizers (e.g., UV-326) or antioxidants |
| Automotive Interior Parts | Stabilizes PP, TPO, and similar substrates to prevent fading, cracking, and surface chalking of components such as instrument panels and door trims under sunlight exposure | Incorporated into the formulation prior to injection molding or compression molding; typical dosage: 0.2–0.4 wt% |
| Cable Sheathing | Enhances weather resistance and long-term insulation performance of polyethylene (PE) and cross-linked polyethylene (XLPE) cable outer jackets | Uniformly dispersed with base resin and additives (e.g., flame retardants) in internal mixers or twin-screw extruders |
| Synthetic Fibers | Used in polypropylene (PP) fiber spinning to improve UV resistance of outdoor textiles (e.g., geotextiles, shade nets) | Incorporated into chips or masterbatch prior to melt spinning; processed via high-temperature melt spinning |
Manufacturing Quality Control of Light Stabilizer 622
| Test Item | Common Test Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and form (usually white or light yellow powder), check for foreign matter or clumping. |
| Melting Point | Capillary Melting Point Apparatus Method | Determine the melting temperature range (typically about 100–135°C) using a melting point apparatus to assess purity and thermal stability. |
| Volatile Matter | Oven Drying Loss Method | Dry the sample at a specified temperature (e.g., 105°C) for a set time, calculate the percentage of mass loss to control moisture and volatile impurities. |
| Ash Content | High-Temperature Ashing Method | Ignite the sample at high temperature (e.g., 800°C) until constant weight, determine the residual inorganic content to assess inorganic impurities. |
| Content (Main Component) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase column and UV detector (e.g., 230 nm), quantify the purity of the main component by external standard method (typically ≥98%). |
| Amine Value | Acid-Base Titration | Titrate with standard hydrochloric acid solution to determine the content of tertiary amine groups, reflecting the proportion of active structural units. |
| Transmittance | UV-Visible Spectrophotometry | Prepare a solution of certain concentration and measure transmittance at specific wavelengths (e.g., 425 nm or 500 nm) to evaluate color-related impurities. |
| Moisture | Karl Fischer Titration | Determine trace moisture content using potentiometric or volumetric titration to ensure product storage stability. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Analyze regulated elements (e.g., lead, cadmium, mercury, arsenic) after acid digestion to meet RoHS or REACH regulation requirements. |
| Solubility Test | Solvent Dissolution Observation | Test solubility in common solvents (e.g., toluene, acetone, ethanol) to assess processing suitability. |
