Description

1,4-Bis(2-Hydroxy-3,5-Di-tert-Butylbenzyl)Piperazine, 95% is a high-purity hindered phenolic antioxidant and metal deactivator. This compound is critical for preventing oxidative degradation and extending the service life of polymers and hydrocarbon-based materials. It is essential for manufacturers in the plastics, rubber, and lubricant industries seeking to enhance product stability and performance under demanding conditions.

Application

• Polymer Stabilization: Primary antioxidant for polyolefins (PP, PE), engineering plastics, and synthetic rubbers to prevent thermal and oxidative degradation during processing and end-use.
• Lubricant & Fuel Additive: Functions as an antioxidant and metal deactivator in engine oils, industrial lubricants, greases, and fuels to inhibit sludge formation and viscosity increase.
• Adhesive & Sealant Formulations: Protects the polymer matrix in hot-melt adhesives, sealants, and coatings from oxidative cross-linking and embrittlement.
• Elastomer Production: Used in the stabilization of styrene-butadiene rubber (SBR), ethylene-propylene-diene monomer (EPDM), and other synthetic elastomers.
• Wire & Cable Insulation: Provides long-term thermal stability to polyethylene and cross-linked polyethylene (XLPE) insulation materials.
• Synergistic Blends: Often used in combination with secondary antioxidants (e.g., phosphites, thioesters) and UV stabilizers for comprehensive stabilization packages.

Quality Control

Our 1,4-Bis(2-Hydroxy-3,5-Di-tert-Butylbenzyl)Piperazine is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for assay and purity, to ensure it meets the specified 95% minimum purity and consistent performance. Certificates of Analysis (COA) documenting all critical parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) in the container headspace is recommended to preserve efficacy. Keep away from strong oxidizing agents.
