Sulfur content, % 29.5-31.5 Combustion

Softening point, C 95-115 Ring & Ball

Application:

1.Alkylphenol disulfide polymer TB7 is a Sulfur donor for natural and synthetic rubbers.

2.Alkylphenol disulfide polymer TB7 produces a high percentage of mono-sulfidic crosslinks that results in vulcanizates with superior aging characteristics.

3.Alkylphenol disulfide polymer TB7 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 Alkylphenol disulfide polymer TB7 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.Alkylphenol disulfide polymer TB7 also aid in rubber processing.

7.Alkylphenol disulfide polymer TB7 polychloroprene vulcanizates have improved flex life.

8.Alkylphenol disulfide polymer TB7 is also an excellent bleaching agent,antioxidant,catalysts in the disproportionation of rosin or rosin esters.

9.Alkylphenol disulfide polymer VA-TB7 is a good vulcanizing agent for vegetable oils.

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

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, Alkylphenol disulfide polymer TB7 tends to improve dispersion of other additives in the rubber.

3.Crosslink Type: Alkylphenol disulfide polymer TB7 promotes mono-sulfidic crosslinks resulting in vulcanizates with excellent heat and aging resistance.

4.Non-nitrosamine: Alkylphenol disulfide polymer TB7 does not produce nitrosamines like many of the other sulfur donors such as DTDM and the thiurams.

Advantages:

1.Non-nitrosamine

2.Lower tack to make it easier to stock and handle

3.Lower volatility

4.Lower volatile degradation products

5.Good compatibility with many rubber polymers

6.Very good antioxidant properties

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

8.Increase the resinous plasticizer during processing

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

10.Improve the dispersion of other compound ingredients into rubber
