Hexafluoropropylene (HFP), also known as perfluoropropene, is an organic compound with the CAS number 116-15-4. It exists as a colorless, odorless gas at standard conditions and is widely used in the production of high-performance polymers such as fluorinated rubbers and plastics. HFP serves as a key monomer in the synthesis of fluoropolymers, which exhibit exceptional heat resistance, low fluid resistance, corrosion resistance, and solvent resistance. Due to these properties, HFP-based polymers find applications in various industries, including automotive, aerospace, petrochemical, textile, electronics, and household appliances. However, HFP is toxic, and proper safety measures must be taken during production and handling.
