Description

Txpd, Oekanal (n-(p-Tolyl)-N'-(3,5-Xylyl)-p-Phenylenediamine) is a high-performance substituted p-phenylenediamine derivative, recognized as a highly effective antioxidant and antiozonant. Its primary value lies in protecting sensitive materials from oxidative and ozone-induced degradation, thereby significantly extending product service life. This compound is essential for manufacturers in the rubber and polymer industries seeking to enhance the durability and stability of their formulations under demanding environmental conditions.

Application

• Rubber Industry: A critical antiozonant and antioxidant for synthetic rubbers like SBR, NBR, and neoprene, used in tire sidewalls, seals, gaskets, and hoses.
• Polymer Stabilization: Protects engineering plastics and synthetic fibers from thermal-oxidative degradation during processing and end-use.
• Lubricant & Fuel Additive: Serves as an antioxidant additive in industrial lubricants, greases, and fuels to prevent sludge formation and viscosity increase.
• Adhesive & Sealant Formulations: Enhances the aging resistance and long-term performance of high-strength adhesives and elastomeric sealants.
• Wire & Cable Insulation: Used as a stabilizer in the insulation and jacketing of cables to protect against environmental stress cracking.
• Technical Elastomers: Key component in the compounding of automotive belts, vibration dampeners, and other mechanical rubber goods (MRG).

Quality Control

Our Txpd, Oekanal is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and related substances, to meet the stringent requirements of industrial applications. A Certificate of Analysis (COA) detailing purity, identity, and physical properties is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is light-sensitive and easily oxidized; for long-term storage, consider an inert atmosphere (e.g., nitrogen) to maintain optimal efficacy. Keep away from strong oxidizing agents.
