STRUKTOL® ZEH, a rubber soluble zinc soap, is an activator for natural rubber. It is used instead of stearic acid and reduces stress relaxation and primary creep of NR-vulcanizates, especially in combination with soluble EV-systems. STRUKTOL® ZEH-DL is a dry liquid of STRUKTOL® ZEH. As a free flowing powder, it offers processing advantages compared to the high viscous liquid STRUKTOL® ZEH. STRUKTOL® ZEH and STRUKTOL® ZEH-DL can be used for masticating natural rubber like other soluble zinc soaps. STRUKTOL® ZEH offers heat stability (reversion resistance) in natural rubber compounds containing normal levels of sulfur, particularly with thiazole accelerators. STRUKTOL® ZEH and STRUKTOL® ZEH-DL can partly replace stearic acid in synthetic rubber like SBR and NBR. Constant physical values such as tensile strength and elasticity can be achieved caused by the good dispersion of the soluble activator.
