ZXCHEM Polymerized 2,2,4-Trimethyl-1,2-dihydroquinoline (TMQ) China supplier — Amber to brown granules
PRODUCT IDENTIFICATION

Polymerized 2,2,4-Trimethyl-1,2-dihydroquinoline (TMQ) at a Glance

TMQ is polymerized 2,2,4-trimethyl-1,2-dihydroquinoline, an amine-type rubber antioxidant also known as rubber antioxidant RD. CAS 26780-96-1 identifies the oligomeric material, supplied as amber to brown granules. Its repeat unit is C12H15N; a repeat-unit formula weight is distinct from the molecular-weight distribution of the commercial polymer. Supply specification: Dimer + trimer + tetramer ≥40%. ZXCHEM supplies this material from China in 25 kg bags.

Storage & Shipping

Storage Conditions

Store tightly closed in a cool, dry and well-ventilated place. Protect from moisture, excessive heat and ignition sources. Segregate from strong oxidizers, strong acids and strong bases.

Packaging Integrity

Inspect bag liners and pallet wrapping for punctures or moisture before unloading. Use clean, dry tools, keep lot labels with the material and reseal opened bags promptly.

Packaging

25 kg bags

Handling & Protection

Control airborne dust with effective local extraction. Avoid dust accumulation, sparks and static discharge; use suitable non-sparking collection tools. Wear protective gloves, goggles and work clothing, and use suitable respiratory protection when the exposure assessment requires it.

What Is Polymerized 2,2,4-Trimethyl-1,2-dihydroquinoline (TMQ)?

TMQ is polymerized 2,2,4-trimethyl-1,2-dihydroquinoline, an amine-type rubber antioxidant also known as rubber antioxidant RD. CAS 26780-96-1 identifies the oligomeric material, supplied as amber to brown granules. Its repeat unit is C12H15N; a repeat-unit formula weight is distinct from the molecular-weight distribution of the commercial polymer.

The supply specification controls softening point at 80–100°C, heating loss and ash at ≤0.30% each, ethanol-insoluble material at ≤0.20%, and the combined dimer, trimer and tetramer fraction at ≥40%. Typical density is approximately 1.05 g/cm³. Review these supply limits with the agreed specification and the batch certificate of analysis.

Rubber formulators evaluate TMQ for heat and oxidative ageing resistance in natural rubber and selected synthetic rubber compounds, including SBR and BR. Typical development areas include tyres, industrial hoses, belts, cables and other technical rubber articles. Confirm dispersion, vulcanization behaviour and aged mechanical performance in the complete compound.

TMQ is a staining amine antioxidant; evaluate colour-sensitive and light-coloured applications carefully. Standard packing is 25 kg bags. Store cool, dry and sealed, control dust and ignition sources, and prevent environmental release. The matched solid reference is non-dangerous goods for transport; it nevertheless carries a chronic aquatic hazard and a combustible-dust warning.
