1. Product Introduction & Main Application
Arnico’s 1,3-Butadiene is a colorless gas with a mild gasoline-like odor, liquefied under pressure, and is one of the most important monomers in the petrochemical industry, obtained from the steam cracking of naphtha and extracted from the C4 fraction. This diolefin, with two conjugated double bonds, is the irreplaceable raw material for the production of various synthetic rubbers (SBR, PBR), high-impact ABS plastic, and Nylon 66.

3. Features & Benefits
-
Conjugated Diene Structure: Two conjugated double bonds allow for high-efficiency copolymerization reactions with styrene and acrylonitrile.
-
Guaranteed Polymer Purity: Free from acetylenes, which are deadly poisons for anionic and coordination polymerization catalysts, preserving the final rubber’s properties.
-
TBC Inhibitor Present: Prevents spontaneous and dangerous polymerization (popcorn polymer formation) during storage and transport.
-
ABS Raw Material: Creates the impact-resistant rubbery phase in ABS plastics used in home appliances and automobiles.
4. Industrial Applications
-
Tire Industry: The primary monomer in Styrene-Butadiene Rubber (SBR) and Polybutadiene Rubber (PBR) for tire treads and sidewalls.
-
High-Impact Plastics: The production of ABS (e.g., vacuum cleaner bodies, car dashboards) and ABS latex.
-
Nylon Production: The raw material in the synthesis route for adiponitrile and hexamethylene diamine for Nylon 66.
-
Specialty Rubbers: The production of Neoprene (Polychloroprene) and Nitrile Rubber (NBR).
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): This gas is extremely flammable, explosive, and carcinogenic. Its inhalation is hazardous. The Arnico MSDS is mandatory and vital.
-
Storage Conditions: Store exclusively in pressurized spherical tanks or refrigerated tanks, completely under an inert gas blanket and away from oxygen, heat, sparks, and direct light. The TBC inhibitor level must be checked regularly.
-
Personal Protective Equipment (PPE): The use of anti-static and solvent-resistant clothing, anti-spark shoes, a Self-Contained Breathing Apparatus (SCBA), and continuous monitoring systems is mandatory.
6. Quality Assurance & COA
Arnico Butadiene shipments are accompanied by a Certificate of Analysis (COA) with a precise GC analysis for purity and acetylenes.
