Product Description TBzTD–70 has safe scorch and high curing rate in natural and synthetic rubber. Alkaline accelerator, e.g. aldehyde amine or guanidine, imparts active effect to TBzTD–70. TBzTD–70 won’t release carcinogenic nitrosamine. Generally, TBzTD–70 combines with sulfur as primary curing accelerator or with thiazol as assistant one.


Processing Characteristics Generally, TBzTDpowderadheres to devices easily, disperses difficultly in mixing process. However, TBzTD–70has good dosing and mixing property, and won’t cake at ordinary temperature and humidity. It has good fluidity, no irritating dust and no material loss. It keeps optimal activity of TBzTDand easily disperses in kinds of rubber compounds.


Dosage As primary accelerator: 0.2~2.0 phr TBzTD-70 with 0.9~2.8 phr S-80;

             As secondary accelerator: 0.2~0.5 phr TBzTD-70 with 1.1~1.6 phr DM-75;

             In non-sulfur curing system: 2.4~3.8 phr TBzTD-70 with 0.53~1.1 phr DM-75.


Applications Used in heat-resistance products, e.g. cable sheath, rigid vulcanizate, and etc..


Packaging Coextruded paper bags lined with plastic film, net weight 25Kg/bag.


Storage Store in a cool, dry, well-ventilated area away from sunlightfor up to 1 year.


Safety and toxicity Refer to related MSDS.
