TMTD

TMTD is a fast-curing accelerator and vulcanizing agent widely used in the rubber industry for natural rubber, synthetic rubbers, latex systems, and specialty elastomers.
TMTD provides ultra-accelerated curing performance, excellent scorch safety, and strong crosslink density in vulcanized rubber compounds.
TMTD functions both as a primary accelerator and as a sulfur donor, enabling sulfur-free or low-sulfur vulcanization systems.
TMTD is valued for its efficiency, consistency, and performance in tire, footwear, cable, hose, and molded rubber applications.
