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's(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.
