Description

Tetrafluoroethylene (CAS NO 116-14-3) is a fundamental fluorocarbon monomer essential for the production of high-performance polymers. Its primary value lies in its role as the key building block for polytetrafluoroethylene (PTFE), a material renowned for its exceptional chemical resistance, thermal stability, and low friction properties. This gaseous, highly volatile compound is critically needed by manufacturers in the chemical, plastics, and advanced materials industries.

Application

• Primary Monomer for PTFE Production: The predominant use is in the synthesis of polytetrafluoroethylene, the polymer sold under trademarks like Teflon®.
• Fluoropolymer Manufacturing: Serves as a co-monomer for producing various fluorinated ethylene propylene (FEP), perfluoroalkoxy (PFA), and other specialty fluoropolymers.
• Chemical Intermediate: Used in organic synthesis to introduce the tetrafluoroethylene group into more complex molecules for pharmaceuticals and agrochemicals.
• Refrigerant and Propellant Precursor: Acts as a starting material in the manufacture of certain hydrofluoroolefin (HFO) refrigerants.
• Electrical and Wire Insulation: The resulting PTFE and copolymers are used for high-temperature, high-performance wire and cable insulation.
• Industrial Coatings and Linings: Provides non-stick, corrosion-resistant properties for cookware, industrial equipment, and pipe linings.

Quality Control

Our Tetrafluoroethylene is produced and handled under stringent quality management systems to ensure batch-to-batch consistency and high purity, which is critical for polymerization processes. Quality is verified through comprehensive analytical testing including gas chromatography (GC) for assay and impurity profiling. A Certificate of Analysis (COA) detailing specific results for purity, moisture, and other critical parameters is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its gaseous and highly volatile nature, it must be stored in approved pressure cylinders in a cool, well-ventilated area away from direct sunlight, heat sources, and ignition points. Storage temperature should not exceed 50°C (122°F). Cylinders must be secured to prevent falling and handled with appropriate equipment for compressed gases.
