PROPERTIES:
It is yellow powder or granule with little osmyl and taste bitter. The density is 1.42-1.52.it is soluble in ethyl acetate, ethanol, solution of NaOH and Na2CO3, insoluble in benzene, water and gasoline.Lower explosion limit is 21g/m3.
APPLICATION:
- As the main universal acid accelerator, it is widely used in NR, IR, SBR, NBR, EPDM, IR and other synthetic rubber products. Its vulcanizates have good physical and mechanical properties.
- It has rapid vulcanization in natural rubber and sulfur-vulcanized synthetic rubber. Its critical temperature for vulcanization is low (125° C). In particular, when the compound contains reinforced alkali furnace black, it is easy to scorch when mixing, and anti-scorching agent is properly added. Improves its safety.
- In sulfur-free low-sulfur curing system and chloroprene rubber as anti-caustic agent and vulcanization retarder;
- Higher activity can be obtained in combination with other substances such as thiazoles, thiurams, dithiocarbamates, quinones, aldehydes, and basic substances.
- MBT-80GE is a pre-dispersed masterbatch, easy weighing, processing does not fly, does not leak, taste is small, is conducive to the health of employees; easy to disperse, no loss, to ensure stable performance of the vulcanized products;
- This product is bitter and unfavorable for use in food contact rubber products.
