Rubber Accelerator MBTS/DM

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
