Application:

①　Amylphenol disulfide polymer 5is a Sulfur donor for natural and synthetic rubbers.

②　Amylphenol disulfide polymer 5produces a high percentage of mono-sulfidic crosslinks that results in vulcanizates with superior aging characteristics.

③　Amylphenol disulfide polymer 5 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 Amylphenol disulfide polymer 5 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　Amylphenol disulfide polymer 5 also aid in rubber processing. 

⑦　Amylphenol disulfide polymer 5 polychloroprene vulcanizates have improved flex life.

⑧　Amylphenol disulfide polymer 5 is also an excellent bleaching agent,antioxidant,catalysts in the disproportionation of rosin or rosin esters.

Characteristics:

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

②　Synergism: Can be used with most typical rubber accelerators and sulfur. When used as a partial replacement for sulfur, Amylphenol disulfide polymer 5 tends to improve dispersion of other additives in the rubber.

③　Crosslink Type: Amylphenol disulfide polymer 5 promotes mono-sulfidic crosslinks resulting in vulcanizates with excellent heat and aging resistance.

④　Non-nitrosamine:Amylphenol disulfide polymer 5 does not 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
