5. Property
White or light yellow powder or granule, slightly bitter, non-toxic, specific gravity of 1.45-1.54, melting point above 160℃; soluble in chloroform, partially soluble in benzene, ethanol, and carbon tetrachloride, insoluble in gasoline, water and ethyl acetate; stable in storage.
6. Use
MBTS can be used as the accelerator for natural rubber and synthetic rubber. It can generate smooth and medium-speed vulcanization with high vulcanization temperature. It is safe to handle and easy to disperse. It does not produce pollution and it has resistance to aging.
DM is mainly used to produce tires, rubber tubes, rubber shoes, rubberized fabric, and other general industrial products. It plays the role of plasticizer or delaying agent when used in neoprene.
7. Packaging
Woven bag lined with plastic bag, orkraft paper bag, 25kg/bag, or as per customer requirements
