Industrial Applications of Antioxidant 1330
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Processing stabilizer for polypropylene (PP) | Added during post-polymerization treatment or pelletization of PP to prevent thermal-oxidative degradation at high processing temperatures and maintain melt flow rate. |
| Plastics Industry | Processing stabilizer for high-density polyethylene (HDPE) | Incorporated during ethylene polymerization or compounding/pelletization to provide long-term thermal stability and prevent polymer chain scission during processing. |
| Plastics Industry | Antioxidant for cross-linked polyethylene (XLPE) wire and cable insulation compounds | Used as primary antioxidant in peroxide cross-linking systems to protect the polymer matrix at cross-linking temperatures, preventing scorching and excessive degradation. |
| Plastics Industry | Polystyrene (PS) and modified PS materials | Added during termination of styrene polymerization or extrusion pelletization to prevent discoloration and loss of physical properties during processing. |
| Rubber Industry | Stabilizer for synthetic rubbers (e.g., nitrile rubber, styrene-butadiene rubber) | Added during rubber latex coagulation or drying to prevent thermo-oxidative aging during storage and subsequent processing (e.g., vulcanization). |
| Adhesives Industry | Hot-melt adhesives | Incorporated during compounding and mixing of hot-melt adhesives to enhance resistance to thermal aging and prevent viscosity changes and charring during high-temperature application. |
| Coatings & Inks | Unsaturated polyester resins and coatings | Added during resin synthesis or coating formulation to improve weatherability and thermal stability of the cured film. |
| Fiber Industry | Polypropylene fibers (polypropylene filament) | Added during spin extrusion to protect fiber tensile strength and color stability during high-temperature drawing and post-treatment. |
Manufacturing Quality Control of Antioxidant 1330
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and state of the sample (usually a white to pale yellow crystalline powder) to determine if it meets the specified standards. |
| Melting Point | Capillary Melting Point Method | Determine the melting temperature range of the sample (typically around 240–245°C) using a melting point apparatus, to evaluate purity and crystallinity. |
| Purity (Main Component) | High-Performance Liquid Chromatography (HPLC) | Separate using a C18 reversed-phase column, and quantify using a UV detector (e.g., 275 nm), calculating the content by external standard method or area normalization. |
| Volatile Matter | Drying Loss Method (Oven Method) | Dry the sample at a specific temperature (e.g., 105°C) until constant weight, measure the percentage of mass loss to control moisture and volatile substances. |
| Ash Content | High-Temperature Incineration Method | Incinerate the sample in a high-temperature muffle furnace (e.g., 800°C) until constant weight, determine the proportion of residual inorganic matter to assess inorganic impurities. |
| Color | Platinum-Cobalt Colorimetric Method / Spectrophotometry | Prepare a solution and compare with standard color grades or measure absorbance at a specific wavelength to evaluate the color purity of the product. |
| Heavy Metal Content | Atomic Absorption Spectrometry (AAS) or ICP-MS | Digest the sample and determine the residual levels of heavy metals such as lead, arsenic, cadmium, and mercury to ensure they meet safety limits. |
| Organic Impurities | Gas Chromatography (GC) or HPLC | Separate and detect synthetic by-products or degradation products (such as unreacted raw materials, isomers, etc.) to control the total impurity level. |
| Hydroxyl Value (Optional) | Acetylation Method | Perform an acetylation reaction with acetic anhydride, then titrate the free acid to indirectly calculate the hydroxyl group content, assisting in assessing structural integrity. |
