Curing agent DTDM - 80 , White Granule , Used In NR , SBR, NBR And EPDM Products.
Recommendations and Applications:
DTDM is able to release free sulfur at normal vulcanization conditions.
Differ from normal sulfur , it imparts singer sulfur bond and double sulfur bond of the vulcanizates,
as well as outstanding heat aging resistance.
As a curing agent, it is better than thiuram disulfide because of no blooming caused.
Process safety is improved because of the DTDM early decomposition
caused by acid in the compound.
This product is usually used in compound which demand in low compression set and excellent
heat aging resistance.
Mainly used in anti vulcanization reversion NR products ,
hot aging resistance SBR , NBR and EPDM products. .
.
