Procurement Specs UV-5050 Density 1.03 | NINGBO INNO
Technical Procurement Specs: Verifying UV-5050 Density 1.03 Tolerances
Procurement of UV Absorber UV-5050 requires strict validation of physical constants, specifically density tolerances at 25°C. The target specification for this composite UV absorber is 1.03 g/cm³, with acceptable industrial tolerances typically ranging between 1.02 and 1.04 g/cm³. Deviations outside this window often indicate impurities in the benzotriazole backbone or incomplete synthesis reactions. When evaluating a liquid light stabilizer batch, purchasers must request a Certificate of Analysis (COA) that explicitly lists density measurements alongside refractive index data. NINGBO INNO PHARMCHEM CO.,LTD. maintains tight control over these parameters to ensure batch-to-batch consistency essential for high-performance coatings.
For detailed product specifications and to secure supply of the UV Absorber UV-5050 liquid light stabilizer, technical teams should cross-reference the provided COA against internal quality standards. The CAS number 104810-48-2 identifies the specific chemical structure, but physical properties like density are the primary indicators of bulk quality during incoming inspection. Viscosity is another critical parameter, usually measured at approximately 1500-2500 mPa·s at 25°C, which affects pumpability in automated dosing systems.
Performance Benchmarking for UV Absorber UV-5050 in Industrial Applications
In industrial applications, the efficacy of UV-5050 is measured by its ability to absorb harmful UV radiation while maintaining thermal stability during polymer processing. This coating additive is frequently evaluated against market standards to determine its viability as a Tinuvin 5050 equivalent. Performance benchmarking involves accelerated weathering tests such as QUV exposure, where gloss retention and color change (Delta E) are monitored over time. The synergistic blend of UV absorbers and hindered amine light stabilizers (HALS) within the UV-5050 formulation provides superior protection compared to single-component stabilizers.
Technical teams often require comparative data to validate formulation changes. You can review specific UV Absorber UV-5050 Tinuvin 5050 Equivalent Performance Benchmark Data to understand how this material performs under stress. The table below outlines key physical and performance parameters typically expected for this class of chemistry.
| Parameter | Standard Specification | Typical Test Method |
|---|---|---|
| Density (25°C) | 1.03 ± 0.02 g/cm³ | ASTM D4052 |
| Purity (GC-MS) | > 95.0% | Gas Chromatography |
| Viscosity (25°C) | 1500 - 2500 mPa·s | ASTM D2196 |
| Flash Point | > 100°C | ASTM D93 |
| UV Absorption Max | 300 - 400 nm | UV-Vis Spectroscopy |
Consistency in these parameters ensures that the UV-5050 alternative integrates seamlessly into existing solvent-based or high-solid formulations without causing haze or precipitation. Thermal stability is particularly crucial for coil coatings and automotive finishes where curing temperatures exceed 200°C.
Supply Chain Logistics for Bulk UV Absorber UV-5050 Orders
Logistics for bulk chemical orders involve careful planning regarding packaging, hazardous material classification, and lead times. UV-5050 is typically supplied in 200kg steel drums or IBC totes, depending on the volume required by the manufacturing facility. As a liquid light stabilizer, it requires storage in a cool, dry place away from direct sunlight to prevent premature degradation before use. Supply chain managers must account for shipping durations when planning production runs, as international freight for specialty chemicals can vary based on port congestion and regulatory inspections.
When sourcing a UV-5050 alternative, it is vital to confirm the supplier's capacity to meet continuous demand without interruption. Bulk synthesis campaigns are usually scheduled quarterly, so aligning procurement contracts with these production cycles ensures priority allocation. Incoterms should be clearly defined, with FOB and CIF being common for international transactions. Proper documentation, including packing lists and commercial invoices, must accompany every shipment to facilitate customs clearance.
Quality Assurance Protocols for UV-5050 Density Consistency
Quality assurance protocols focus on maintaining density consistency and chemical purity across all production batches. Every batch of coating additive undergoes rigorous testing using Gas Chromatography-Mass Spectrometry (GC-MS) to identify any trace impurities that could affect performance. The density measurement is not merely a formality; it serves as a quick check for gross contamination or formulation errors. If the density deviates significantly from 1.03 g/cm³, the batch is quarantined for further analysis.
Internal QA teams utilize statistical process control (SPC) charts to monitor trends in viscosity and density over time. This data-driven approach allows for early detection of process drifts before they result in out-of-spec material. Customers receiving shipments should perform incoming quality control (IQC) checks on a representative sample from each drum. Verifying the refractive index alongside density provides a dual-validation method to ensure the material matches the COA provided by the manufacturer.
Regulatory Compliance Certifications for UV-5050 Sourcing
Sourcing chemical raw materials requires verification of quality management systems and safety documentation. While regulatory landscapes vary by region, suppliers should provide comprehensive Safety Data Sheets (SDS) and Technical Data Sheets (TDS) with every order. NINGBO INNO PHARMCHEM CO.,LTD. adheres to strict quality management standards to ensure all documentation is accurate and up-to-date. For formulators seeking a compliant composite UV absorber, verifying the supplier's ISO certification status is a standard due diligence step.
Documentation should also include statements regarding restricted substances, ensuring the material is free from heavy metals or prohibited compounds listed in global inventory schemes. For those evaluating this material as a potential substitute, reviewing the UV Absorber UV-5050 Drop-In Replacement For Tinuvin 5050 guide can clarify compatibility with existing regulatory filings. Always ensure that the SDS reflects the most current composition data to maintain compliance with workplace safety regulations.
