Application:

● Alkylphenol disulfide polymer J1700 is a Sulfur donor for natural and synthetic rubbers.
● Alkylphenol disulfide polymer J1700 produces a high percentage of mono-sulfidic crosslinks that results in vulcanizates with superior aging characteristics.
● Alkylphenol disulfide polymer J1700 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 J1700 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 J1700 also aid in rubber processing.  
● Alkylphenol disulfide polymer J1700 polychloroprene vulcanizates have improved flex life.
● Alkylphenol disulfide polymer J1700 is also an excellent bleaching agent,antioxidant,catalysts in the disproportionation of rosin or rosin esters. 
● Alkylphenol disulfide polymer J1700 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 J1700 tends to improve dispersion of other additives in the rubber.
● Crosslink Type: Alkylphenol disulfide polymer J1700 promotes mono-sulfidic crosslinks resulting in vulcanizates with excellent heat and aging resistance.
● Non-nitrosamine: Alkylphenol disulfide polymer J1700 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
