Description

Decafluorobutane CAS NO 355-25-9 is a fully fluorinated alkane, also known as perfluorobutane, characterized by its high chemical and thermal stability. This inert, non-flammable gas is a critical component in applications demanding extreme reliability and a low environmental impact. It serves as a key material for manufacturers in the electronics, aerospace, and specialty chemical industries, where its unique properties enable advanced technological solutions.

Application

• Electronics Manufacturing: Used as a plasma etching and chamber cleaning gas in semiconductor fabrication due to its high etch selectivity and stability.
• Aerospace & Military: Functions as a dielectric coolant and heat transfer fluid in advanced radar and electronic warfare systems.
• Fire Suppression: Serves as a clean agent in specialized fire extinguishing systems for protecting sensitive equipment, leaving no residue.
• Polymer & Material Science: Acts as a blowing agent for producing high-performance fluoropolymer foams with fine, uniform cell structures.
• Medical Devices: Employed as a propellant in metered-dose inhalers (MDIs) and as a contrast agent enhancer in ultrasound imaging.
• Leak Testing & Refrigeration: Utilized as a tracer gas for precision leak detection and as a refrigerant in low-temperature cooling cycles.
• Chemical Synthesis: Acts as a stable solvent or reagent in fluorination reactions and specialty organic synthesis.
