STRUKTOL® ZEH

STRUKTOL® ZEH by Struktol is zinc 2-ethylhexanoate-based activator for natural rubber. It reduces stress relaxation and primary creep of NR-vulcanizates, especially in combination with soluble EV-systems. STRUKTOL® ZEH offers heat stability (reversion resistance) in natural rubber compounds containing normal levels of sulfur, particularly with thiazole accelerators. It is used for masticating natural and synthetic rubber. It can partly replace stearic acid in synthetic rubber like SBR and NBR. Tensile strength and elasticity can be achieved caused by the good dispersion of the soluble activator. The recommended dosage level is 1-3 phr. The shelf life of this product is 2 years.
