Applications:

1.It is a nitrosamine free sulfur donor for natural and synthetic rubbers.

2.It  produces a high percentage of mono-sulfidic crosslinks that results in vulcanizates with superior aging characteristics.

3.It  can be used as either complete or partial replacements for sulfur and thiuram and DTDM sulfur donors in EV and semi-EV type cure systems.  

4.In tires it is used in the inner-liner, chafer,bead apex, sidewalls, and tread. 

5.Industrial applications include noise damping blocks, motor mounts, dock fenders, elastic threads, automobile engine hoses, gaskets, belts, and other industrial rubber products that require good heat resistance.

6.It also aid in rubber processing.  

7.Dosage for reference: 0.5~20 phr.2 phr is most preferably


Features

①Polymers: Natural rubber and synthetic elastomers. Especially good in curing rubber that contains chlorine such as chlorobutyl and polychloroprene.

②Synergism: Can be used with most typical rubber accelerators and sulfur. When used as a partial replacement for sulfur, its polymer tends to improve dispersion of other additives in the rubber.

③Crosslink Type: It promotes mono-sulfidic crosslinks resulting in vulcanizates with excellent heat and aging resistance.

④Non-nitrosamine: It doesn’t produce nitrosamines like many of the other sulfur donors such as DTDM and the thiurams. 


Advantages:

①Non-nitrosamine

②Lower tack to make it easier to stock and handle

③Lower volatility

④Lower volatile degradation products

⑤Good compatibility with many rubber polymers

⑥Very good antioxidant properties

⑦Improve heat age properties of vulcanizates because of its generation of mono- and di-sulfic crosslinks

⑧Increase the resinous plasticizer during processing

⑨Increase the green tack in NBR,BR and SBR based compounds

⑩Improve the dispersion of other compound ingredients into rubber
