Product Description:
Application:
● Amylphenol disulfide oligomer VA-5 is a Sulfur donor for natural and synthetic
rubbers.
● Amylphenol disulfide oligomer VA-5 produces a high percentage of mono-sulfidic crosslinks that results in vulcanizates with superior aging characteristics.
● Amylphenol disulfide oligomer VA-5 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 Amylphenol disulfide oligomer VA-5 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.
● Amylphenol disulfide oligomer VA-5 also aid in rubber processing.
● Amylphenol disulfide oligomer VA-5 polychloroprene vulcanizates have improved flex life.
● Amylphenol disulfide oligomer VA-5 is also an excellent bleaching agent, antioxidant, catalysts in the disproportionation of rosin or rosin esters.
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, Amylphenol disulfide polymer 5 tends to improve dispersion of other additives in the rubber.
● Crosslink Type: Amylphenol disulfide polymer 5 promotes mono-sulfidic crosslinks resulting in vulcanizates with excellent heat and aging resistance.
● Non-nitrosamine: Amylphenol disulfide polymer 5 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
