1-Butene
1-Butene
Formula: C4H8
CAS No: 106-98-9
1-Butene (C4H8) is a colorless, flammable, liquefied gas with a slight aromatic odor. This linear alpha-olefin is part of the alkene hydrocarbon family and is shipped as a liquid under its own vapor pressure. It is an essential building block in polymer manufacturing and specialty chemical production.
Applications include:
-
Comonomer in polyethylene production, primarily in linear low-density polyethylene (LLDPE) to improve film strength, puncture resistance, and flexibility.
-
Chemical intermediate for polypropylene resins, 1,2-butylene oxide, methylethylketone (MEK), maleic anhydride, and n-butyl derivatives.
-
Solvent for specialty chemical and process applications.
EFC Gases & Advanced Materials supplies high-purity 1-Butene with rigorous analytical verification to meet the stringent requirements of polymer, coatings, and specialty chemical industries. Controlled packaging, handling, and logistics ensure product integrity from production through delivery.
