Isophthalic Formylhydrazine (IDH) is a kind of aromatic dicarboxylic dihydrazide crosslinker, which can act with rubber through "bridging" reaction to improve the heat resistance, weather resistance, mechanical properties and other properties of the polymer. Its use in the tread base of construction machinery radial tire can significantly reduce the dynamic heat generation of the tire, increase the heat transfer rate, significantly increase the durability of the tire, and do not affect its mechanical properties.
