◆ UHOO DETU has low accelerate performance and poor anti-scorching, so it has been rarely used in diene rubber. But in special circumstances, such as vulcanizing with thiuram sulfide, UHOO DETU has the role of active agent.

◆ UHOO DETU has the unique effet for the vulcanization of CR. UHOO DETU can be obtained vulcanized CR with the good performance of tensile strength, hardness, compression. Compared with ETU, its scorch and vulcanization speed are fast, and the vulcanization flatness is better.

◆ UHOO DETU is easy to disperse, not bloom. UHOO DETU is especially suitable for continuous vulcanization of extruded products. UHOO DETU also used as the vulcanizing agent for IIR and EPDM. UHOO DETU has the antioxidant effect for NR, CR, NBR and SBR.

◆ Generally used for the manufacture of industrial products. Special wire sponge timing belt, V belt, molding, injection and extrusion products.
