Product Description:
Specifications:
Vultac TB7 equivalent
Composition: Para tert butylphenol disulfide(> 95 % ) + sulfur(<
3 %)
Item Standard Test Way
Appearance Yellow to light brown pastilles or powder Visual
Sulfur content, % 29.5-31.5 Combustion
Softening point, ℃ 95-115 Ring & Ball
Vultac TB710 equivalent
Composition:Para tert butylphenol disulfide(90 % ) + sulfur(< 3 %)+stearic acid(10%)
Item Standard Test Way
Appearance brown pastilles or powder Visual
Sulfur content, % 26.4-28.4 Combustion
Softening point, 75-95 Ring & Ball
Stearic acid content, % 9.0-11.0 FTIR
Application:
Alkylphenol disulfide polymer TB7 /TB710 is a Sulfur donor for natural and synthetic rubber
Alkylphenol disulfide polymer TB7/TB710 produces a high percentage of mono-sulfidic crosslinks that results in vulcanizates with superior aging characteristics.
Alkylphenol disulfide polymer TB7/TB710 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 TB7/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 TB7/TB710 also aid in rubber processing.
Alkylphenol disulfide polymer TB7/TB710 polychloroprene vulcanizates have improved flex life.
Alkylphenol disulfide polymer TB7/TB710 is also an excellent bleaching agent, antioxidant, catalysts in the disproportionation of rosin or rosin esters.
Alkylphenol disulfide polymer VA-TB7/TB710 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 TB7/TB710 tends to improve dispersion of other additives in the rubber.
Crosslink Type: Alkylphenol disulfide polymer TB7 /TB710 promotes mono-sulfidic crosslinks resulting in vulcanizates with excellent heat and aging resistance.
Non-nitrosamine: Alkylphenol disulfide polymer TB7/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
Increase the green tack in NBR, BR and SBR based compounds
Improve the dispersion of other compound ingredients into rubber
Package:
25kgs/paper drum;25kgs/kraft bag or as customers request;
Storage:
It should be stored in dry & cool environment(below 86 °F/30℃) in closed original containers.
