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
