High Efficient Deoxidizer For Polypropylene - China

price: contact company for price

The distinct features of type PPP deoxidizers are: To propylene with

the unstable double bonds, it is not accompanied by any secondary

reaction such as addition reaction, polyreaction, oxidation reaction

and so on. That is why it is special for liquid phase propylene

deoxidizing. The adsorption of type PPP to hydrogen (H2) is weak, so

when it is reactivated by H2, only little H2 is adsorbed, thus the

temperature runaway caused by hydrogenation reaction does not occur

while the transportation of propylene, therefore it is safe and

reliable. Deep deoxidizing, high capacity of operation oxygen, long

useful time are also its characters. Main Technical Performance of PPP
