Alkyl phenol disulfide polymer

"Alkyl phenol disulfide polymer" is listed under  Chemical Category

Alkylphenol disulfide polymer TB7Composition: Para-tert-butylphenol disulfide(> 95 Percent ) + sulfur(< 3 Percent) CAS NO.:60303-68-6Synonym:Mixture of tert-butylphenol disulfide polymer and sulfurArkema Vultac TB7 equivalentPoly-tert-butylphenol disulfide Para-tert-butylphenol disulfide polymerAlkylphenol disulfide polymer sulfur donorAlkylphenol disulfide polymerPara-tertiobutylphenol Disulfide Polymer Tert-butylphenol disulfide polymerCuring ResinSpecification:ItemStandardTest WayAppearanceYellow to light brown pastilles or powderVisual Sulfur content, Percent 29.5-31.5CombustionSoftening point, C 95-115Ring & BallApplication: 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 preferablyCharacteristics: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-nitrosamine2.Lower tack to make it easier to stock and handle3.Lower volatility4.Lower volatile degradation products5.Good compatibility with many rubber polymers6.Very good antioxidant properties7.Improve heat age properties of vulcanizates because of its generation of mono- and di-sulfic crosslinks8.Increase the resinous plasticizer during processing9.Increase the green tack in NBR,BR and SBR based compounds10.Improve the dispersion of other compound ingredients into rubberPackage:25kgs/paper drum25kgs/kraft bag or as customers requestStorage: It should be stored in dry & cool environment(below 86 °F/30 C) in closed original containers.Shelf Life:2 years if stored as indicated above
