Industrial Applications of 80693-00-1
| Industry | Application | Process |
|---|---|---|
| Plastics Industry | Processing stabilizer for polyolefins (e.g., PP, PE) to prevent thermal oxidative degradation | Added during high-temperature processing operations such as extrusion, injection molding, and blow molding; typically used synergistically with primary antioxidants (e.g., hindered phenols) |
| Synthetic Rubber | Long-term heat stabilizer for styrene-butadiene rubber (SBR), polybutadiene rubber (BR), and ethylene-propylene rubber (EPR/EPDM) | Incorporated into the compound during the mixing stage to enhance the heat aging resistance of vulcanized rubber |
| Adhesives & Sealants | Improves high-temperature storage stability of hot-melt adhesives, polyurethane sealants, and similar formulations | Added during melt compounding or devolatilization to inhibit oxidation of base resins and tackifying resins |
| Engineering Plastics | Enhances processing stability of polyamides (PA6, PA66), polycarbonate (PC), and related polymers | Blended with the resin prior to pelletizing or injection molding to minimize polymer chain scission under melt shear conditions |
Manufacturing Quality Control of 80693-00-1
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (PEP 36 content) | HPLC-UV | Quantification by reverse-phase HPLC with UV detection at 275 nm using external standard calibration. |
| Appearance | Visual Inspection | Assessment of physical state and color against reference standard under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid using capillary tube method. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized KOH ethanol solution using phenolphthalein indicator. |
