Taic is multifunctional alkene monomer with aromatic heterocycle. It is not dissolves in water, slightly dissolved in alkane, and completely dissolves in aromatic hydrocarbon, alcohol, acetone, hydrocarbon halides, cyclopentene hydrocarbon. Taic is widely used as the cross-linking agent, modifier and assistant vulcanizer of thermoplastics, ion exchange resin and special rubber. It is also an intermediate of photocureable coating, photoresists and flame retardant. Iron drums or paper bags lined with pvc film bags; net weight: 200kg or 25kg;ibc drum 1000kg net weight. Store in cool, shady, dry and ventilated places. Keep away from moisture, fire and solarization

Brief introduction Tmptma is light yellow transparent liquid, soluble in most organic solution, insoluble in water and alcohol. As cross-linking agent, rubber modifier, tmptma could decrease the radiation dosage, save the radiation time, increase the cross-linking density, low viscosity, high cross-linking properties, low vapour tension, high speed solid. As co-vulcanizing agent applicated in the synthetic rubber, it could improve the properties of anti-corrosion, anti-age and increase the rubber hardness, thermal resistance, absorb the per-oxide product (like dcp) smell when in the process of vulcanizing.Help the rubber more plastic when in the mix process, make the vulcanized rubber more harder. Suitable for mbr, epdm, acm and cr , etc. 25kg/200kg, net, pe drum. Sealed preservation, stored in a cool dark place, retention period a year.
