Description

Sebacic Dihydrazide is a high-purity, white crystalline powder derived from sebacic acid, serving as a key reactive intermediate in polymer synthesis. Its bifunctional hydrazide groups make it an essential cross-linking agent and chain extender, significantly enhancing the thermal and mechanical properties of final materials. This compound is primarily sought by manufacturers in the polymer, coatings, and specialty chemical industries for producing high-performance polyurethanes, epoxy curing agents, and adhesives.

Application

• Polymer Cross-Linking Agent: Used as a chain extender and cross-linker in the production of polyurethane elastomers, foams, and coatings to improve tensile strength and thermal stability.
• Epoxy Curing Agent: Functions as a curing agent for epoxy resins, contributing to enhanced chemical resistance and high-temperature performance in composite materials.
• Synthesis Intermediate: Serves as a key building block in the synthesis of pharmaceuticals, agrochemicals, and corrosion inhibitors.
• Adhesive Formulation: Incorporated into adhesive systems to increase bonding strength and durability under demanding environmental conditions.
• Textile & Leather Auxiliary: Used in the production of finishing agents for textiles and leather to impart improved water repellency and flexibility.
• Fuel & Lubricant Additive: Acts as a precursor for additives that improve the performance and stability of fuels and industrial lubricants.

Quality Control

Our Sebacic Dihydrazide is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is tested against rigorous in-house specifications, which typically include assay, melting point, and impurity profile analysis. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product quality and performance.
