Description

1,1-Dichloroethylene (CAS NO 75-35-4) is a highly reactive and versatile chlorinated hydrocarbon monomer. Its primary commercial value lies in its role as a key intermediate in the synthesis of specialty polymers and copolymers, particularly polyvinylidene chloride (PVDC). This compound is essential for manufacturers requiring a high-purity, reactive building block to impart specific barrier and chemical resistance properties to advanced materials.

Application

• Polymer & Resin Synthesis: Primary monomer for the production of polyvinylidene chloride (PVDC) resins, known for exceptional barrier properties against moisture, gases, and aromas.
• Copolymer Production: Used in copolymerization with vinyl chloride, acrylates, and other monomers to create specialty plastics and elastomers with enhanced chemical and thermal stability.
• Adhesive & Coating Formulations: Serves as a reactive intermediate in the manufacture of high-performance industrial adhesives, sealants, and protective coatings.
• Chemical Intermediate: Acts as a precursor in organic synthesis for the production of various agrochemicals, pharmaceuticals, and other fine chemicals.
• Flame Retardant Additives: Utilized in the development of flame-retardant materials and additives for plastics and textiles.
• Solvent & Extraction Agent: Employed in specialized solvent applications and extraction processes within chemical manufacturing.

Quality Control

Our 1,1-Dichloroethylene is manufactured under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and impurity profiling, to ensure it meets exacting industry and customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile and reactive nature, it must be kept under an inert atmosphere (e.g., nitrogen) to prevent polymerization and stored separately from strong oxidizers, acids, and bases. Recommended storage temperature is 2-8°C for extended stability.
