Overview
Hexafluoropropylene Dimer (C6F12) is a fluorocarbon compound derived from the dimerization of hexafluoropropylene. It is a critical intermediate in the production of advanced fluorinated materials, particularly perfluoropolyethers (PFPEs), which are renowned for their exceptional thermal and chemical resistance. This compound is widely utilized in industries requiring high-performance lubricants, coatings, and sealants. Its unique properties, including low surface energy and non-reactivity, make it indispensable in aerospace, electronics, and semiconductor manufacturing.
Physical and Chemical Properties
Hexafluoropropylene Dimer exists as a colorless gas or liquid under standard conditions. It has a molecular weight of 300.05 g/mol and a density of 1.58 g/cm³ in its liquid state. The compound exhibits a boiling point of 50-52°C and a melting point of -130°C. Its chemical inertness stems from the strong carbon-fluorine bonds, making it resistant to oxidation, acids, and bases. The dimer is insoluble in water but miscible with many organic solvents, facilitating its use in various industrial formulations.
Main Applications
The primary application of Hexafluoropropylene Dimer is in the synthesis of PFPEs, which serve as high-temperature lubricants in aerospace and automotive industries. These lubricants are essential for engines and machinery operating under extreme conditions. Additionally, the dimer is used in the production of specialty coatings for electronics, providing moisture and chemical resistance. Its low surface energy also makes it suitable for anti-fouling coatings and release agents in manufacturing processes.
Safety and Storage
Handling Hexafluoropropylene Dimer requires strict safety measures due to its potential health hazards. Inhalation or skin contact can cause irritation, and prolonged exposure may lead to more severe effects. Always use personal protective equipment (PPE) such as gloves and respirators. Storage should be in a cool, dry, and well-ventilated area, away from ignition sources. The compound should be kept in tightly sealed containers to prevent leakage. Emergency procedures, including spill containment and ventilation, must be in place.
B2B Procurement Guide
When procuring Hexafluoropropylene Dimer, prioritize suppliers with certifications such as ISO 9001 to ensure quality and consistency. Verify the purity level (typically >99%) and request analytical reports for each batch. Consider logistical factors, including packaging (cylinders or drums) and transportation requirements, especially for international shipments. Price negotiation is common, with bulk orders often receiving discounts. Establish long-term contracts with reliable suppliers to secure stable pricing and availability.
