Rubber Accelerator Masterbatch MBT (M)-80

Rubber Accelerator Masterbatch MBT (M)-80 is a yellow powder or granule, serving as a primary acid accelerator in natural and synthetic rubber systems like NR, SBR, NBR, IR, and EPDM. Offering higher activity compared to counterparts like DM and TMTD, it enables low-temperature vulcanization and easy dispersion in rubber without causing pollution.

Widely applied in industrial rubber products such as tires, rubber belts, and shoes, it ensures rapid vulcanization and excellent physical properties. MBT-80GE, available in a pre-dispersed masterbatch form, facilitates easy weighing, minimal odor, and enhanced processing without product loss. However, its bitterness restricts its use in food-contact rubber applications. Packed in 25 kg carton boxes, customizable shipping marks, and a storage validity of 12 months below 25ºC ensure convenience and product integrity for manufacturers.
