Description

1-Butene is a key linear α-olefin monomer and a versatile chemical intermediate essential for the production of high-performance polymers and specialty chemicals. Its reactivity and gaseous nature make it a fundamental building block for creating materials with tailored properties. This product is critical for manufacturers in the plastics, synthetic rubber, and fine chemical industries seeking reliable, high-purity feedstocks.

Application

• Polymer Production: Primary comonomer for the manufacture of linear low-density polyethylene (LLDPE) and high-density polyethylene (HDPE).
• Synthetic Rubber: Key intermediate in the production of butyl rubber and polybutene, used in tire inner liners, sealants, and adhesives.
• Chemical Synthesis: Feedstock for producing secondary butyl alcohol (SBA), butylene oxide, and maleic anhydride.
• Plasticizers & Resins: Used in the synthesis of plasticizers and various hydrocarbon resins.
• Fuel Additives: Component in the alkylation process to produce high-octane gasoline blending components.
• Specialty Chemicals: Starting material for surfactants, lubricant additives, and other olefin-derived chemicals.

Quality Control

Our 1-Butene is produced and handled under stringent quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) for each shipment, detailing key parameters such as purity and critical impurity profiles. Our quality commitment aligns with global industry standards for olefin monomers, ensuring reliability for your sensitive polymerization and synthesis processes.

Storage

Store and handle as a compressed liquefied gas in appropriate pressure-rated containers (e.g., cylinders, tube trailers) in a cool, well-ventilated area. Keep containers tightly closed and away from heat, sparks, open flames, and other ignition sources. Protect from physical damage. Due to its highly volatile and gaseous nature, storage areas must comply with all local and international regulations for flammable gases.
