Triallyl isocyanurate (TAIC) is a trifunctional crosslinking coagent — a heat- and radiation-stable triallyl monomer that boosts peroxide and radiation crosslinking of polymers and rubbers. Identity: CAS 1025-15-6.
What it is
TAIC (CAS 1025-15-6) is a liquid/low-melting triallyl isocyanurate. Its three allyl groups and thermally stable isocyanurate ring make it a high-performance coagent and crosslinker.
How it works
Its allyl groups participate in peroxide- and radiation-initiated crosslinking, raising crosslink density, heat resistance and mechanical properties in polyolefins, EVA, fluoroelastomers and wire-and-cable compounds; it also serves in thermoset and flame-retardant systems.
Applications
TAIC is used as a coagent/crosslinker in peroxide- and radiation-cured polyolefins, EVA, elastomers and wire and cable. Related coagent triallyl cyanurate (TAC).
Forms, grades and handling
TAIC is supplied as a clear liquid/low-melting solid in drums and bulk. Properties are typical reference values; the Certificate of Analysis (CoA) for the lot you buy governs. Isocyanates are moisture-sensitive and require respiratory/skin precautions; handle per the current Safety Data Sheet (SDS). Each lot ships with CoA, TDS and SDS.
Bulk supply and RFQ
RawSource sources Triallyl Isocyanurate direct from producers in bulk, with CoA, TDS and SDS per lot. Tell us your binder system, cure schedule and the performance you need, and we will quote the right grade. See the epoxy curing agents guide.

Frequently Asked Questions
What is triallyl isocyanurate (TAIC) used for?
TAIC (CAS 1025-15-6) is a trifunctional crosslinking coagent that boosts peroxide- and radiation-initiated crosslinking of polyolefins, EVA, elastomers and wire-and-cable compounds, raising crosslink density and heat resistance.
How is bulk triallyl isocyanurate supplied and quoted?
RawSource supplies triallyl isocyanurate in bulk with CoA, TDS and SDS per lot. Pricing is quote-based on grade and volume; submit an RFQ with your binder system and cure schedule.
What is the REACH and TSCA regulatory status of Triallyl Isocyanurate?
Triallyl Isocyanurate (CAS 1025-15-6) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 213-834-7).
