Known by the chemical formula C8H12N4, 2,2'-Azodiisobutyronitrile stands out as a trusted free-radical initiator for resins, rubber, and specialty polymers. Its structure, built from two isobutyronitrile groups joined by an azo bond, means a reliable, controlled release of nitrogen gas and radicals during thermal decomposition. With a specific density near 1.10 g/cm³ and a melting point of 103-105°C, it offers predictable behavior for batch or continuous processing. China-based manufacturers keep a close eye on purity (≥98%), key to high-yield production. Its HS Code is often listed as 2927.00, streamlining international purchase and customs clearance.
Users pay attention to physical form—fine, free-flowing white powder or granule—because this consistency reduces feeding issues in automatic systems. Water solubility matters, but 2,2'-Azodiisobutyronitrile mostly stays inert in aqueous solution, activating just with heat. Companies emphasize strict batch consistency, as deviations can mean poor polymer chain formation. MSDS, SDS, and TDS provide details on handling and performance, letting buyers stay on top of safe use and legal policies. Factories often present their ISO 9001, SGS, Halal, and Kosher certifications, responding to growing demand for verified, safe materials.
2,2'-Azodiisobutyronitrile finds use as a raw material in PVC foaming, ABS resin production, and as a blowing agent for specialty materials. Buyers look for details on solution concentration (liter basis), especially for scalable industrial lines. Responsible suppliers break down safety measures—adequate ventilation, spark-free handling—since the compound carries explosive and harmful inhalation risks. Labels like “harmful” or “hazardous” don’t scare off regular commercial users who trust clear hazard communication and REACH registration, especially from established China-supply chains with proven regulatory records.
China now leads production, with manufacturers offering competitive factory quotes based on minimum order quantities (MOQ), CIF or FOB incoterms, and flexible packaging (fiber drum or carton). Clear communication about purchase options, free sample availability, and expected lead times helps buyers weigh suppliers. Inquiry processes these days happen over multiple channels—email, form, or messaging—speeding up quote responses and building new global customer relationships. Buyers check policy updates to judge supply stability amidst shifting regulations and market pressures.
Companies choosing 2,2'-Azodiisobutyronitrile look beyond the price, demanding OEM production, third-party test sheets, and verified certification. SGS and ISO documentation add confidence, while halal and kosher certificates remove barriers for finished goods sold worldwide. Supplier transparency on product structure, molecular property, and specification means fewer surprises down the line. News about regulation or new uses reaches buyers quickly, helping them adapt to changing needs and new applications in advanced materials, adhesives, and coatings.
For those sourcing 2,2'-Azodiisobutyronitrile, the path looks clear—find a supplier with clear price, structure, regulatory, and safety data, backed by solid documentation. Quality, not just cost, keeps lines moving and products meeting market demands. With buyers able to ask for certificates, material property sheets, and detailed specs before placing orders, the market provides more transparency than ever before.
