Rubber Vulcanizing agent Alkylphenol polysulfide

it is a non-nitrosamine free rubber vulcanizing agent for different NR and SR.sulfur content: 26.4%~28.4%,Softening point:75~95℃ ,stearic acid content 9.0-11.0%.J1710 is a non-nitrosamine curing & vulcanizing agent for natural and synthetic rubbers;it produces a high percentage of mono-sulfidic crosslinks that results in vulcanizates with superior aging characteristics; 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; it can be used in the inner-liner, chafer,bead apex, sidewalls, and tread etc.

Specification:

Application:
● Alkylphenol disulfide polymer VA-TB710 is a Sulfur donor for natural and synthetic rubbers.
● Alkylphenol disulfide polymer VA-TB710 produces a high percentage of mono-sulfidic crosslinks that results in vulcanizates with superior aging characteristics.
● Alkylphenol disulfide polymer VA-TB710can 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 VA-TB710 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 JVA-TB710 also aid in rubber processing.  

● Alkylphenol disulfide polymer VA-TB710 polychloroprene vulcanizates have improved flex life.
● Alkylphenol disulfide polymer VA-TB710 is also an excellent bleaching agent,antioxidant,catalysts in the disproportionation of rosin or rosin esters.
● 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, poly alkyl phenol disulfide polymer VA-TB710 tends to improve dispersion of other additives in the rubber.
● Crosslink Type: poly alkyl phenol disulfide polymer VA-TB710 0 promotes mono-sulfidic crosslinks resulting in vulcanizates with excellent heat and aging resistance.
● Non-nitrosamine: poly alkyl phenol disulfide polymer VA-TB710 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
● Improve the dispersion of other compound ingredients into rubber
