Principal Use 
    1. Trimethylolpropane trimethacrylate could  Improve the properties of ani-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.                                              
    2. Crosslink agent,rubber modifier TMPTMA could decrease the radiation dosage, save the radiation time,increase 
the crosslink density,low viscosity,high crosslik properties,low vapo tensionhigh speed solidity                                                                                    
    3.curable printing ink of UV 、EB or heating,coating, adhesive
Packaging 
    Plastic drums or stainless steel tank，200kg net weight.
