‍

Application: ‍

• Alkylphenol disulfide polymer  ‍‍is a Sulfur donor for natural and synthetic rubber

• ‍‍‍Alkylphenol disulfide polymer produces a high percentage of mono-sulfidic crosslinks that results in vulcanizates with superior aging characteristics.

• ‍‍‍Alkylphenol disulfide polymer  ‍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.  

• ‍‍‍In tires Alkylphenol disulfide polymer  is used in the inner-liner, chafer,bead apex, sidewalls, and tread.

• ‍‍‍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.

• ‍‍‍Alkylphenol disulfide polymer also aid in rubber processing.  

• ‍‍‍Alkylphenol disulfide polymer polychloroprene vulcanizates have improved flex life.

• ‍‍‍Alkylphenol disulfide polymer is also an excellent bleaching agent,antioxidant,catalysts in the disproportionation of rosin or rosin esters.

• ‍‍‍Alkylphenol disulfide polymer is a good vulcanizing agent for vegetable oils.

• ‍‍‍Dosage: 0.5~20 phr.2 phr is most preferably

Characteristics:

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

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

• ‍‍‍●Crosslink Type: Alkylphenol disulfide polymer promotes mono-sulfidic crosslinks resulting in vulcanizates with excellent heat and aging resistance.

• ‍‍‍●Non-nitrosamine: Alkylphenol disulfide polymer does not produce nitrosamines like many of the other sulfur donors such as DTDM and the thiurams.

Advantages:
‍‍‍●‍

• Non-nitrosamine

• ‍●Lower tack to make it easier to stock and handle

• Lower volatility

• ‍Lower volatile degradation products

• ‍Good compatibility with many rubber polymers

• ‍Very good antioxidant properties

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

• Increase the resinous plasticizer during processing

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

• Improve the dispersion of other compound ingredients into rubber
