Product Description DPTT(TRA)-70 has safe scorch and high curing rate in natural and synthetic rubber. It is used as activator or assistant accelerator, can combine with sulfonamide or thiol. A little DPTT(TRA)-70 can increase heat-resistance of vulcanizate combined with thiuram.


Processing Characteristics Generally, DPTT(TRA) powderadheres to devices easily, and disperses difficultly in mixing process. However, DPTT(TRA)-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 DPTT(TRA) and easily disperses in kinds of rubber compounds.


Dosage Generally 0.35 ~ 3.5 phr.


Applications Used in kinds of rubber compounds, especially EPDM and IIR heat-resistance products, such as, rubber hoses, seals and sheath. DPTT(TRA)-70 is also as curing accelerator for CSM combined with DM-80.


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.
