Accelerator DPTT(TRA)-75 , Accelerator Masterbatch , Light Yellow Granule , Used In Heat Resisting Products.
Recommendations and Applications:
DPTT imparts fast curing rate and good scorching safety of natural rubber and synthetic rubber.
And as activator and second accelerator ,
it can be used along with mercaptan and sulfonamide accelerator.
Because of sulfur break down from DPTT after heating, it also can be used as a vulcanizing agent ,
and imparts excellent heat resistance and hot aging resistance of the vulcanizate ,
with very good processing safety.
DPTT is especially suitable for NBR when used along with thiazole accelerator ,
imparts superior compression set and heat resistance.
It is primary accelerator for EPDM and IIR.
Generally used in the manufacture of heat resisting products ,
such as cable , hose , sealing strip , jacket , etc.
As vulcanizing agent , use 1.0~3.0 PHR
As second accelerator , use 0.1~1.0 PHR
Composition:
Pre-dispersed 80% Dipentamethylene thiuramtetrasulfide in a 20% elastomeric binder
Elastomeric binder can be SBR or EPDM , or others according to customer’s requirements.
