Amylphenol disulfide polymer CAS NO. 68555-98-6

Applications:

V2 can be used as a bleaching agent in the disproportionation of rosin or rosin esters.

V3 and V5 is nitrosamie free vulcanizing & curing agent for different rubbers.
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, para tert amylphenol disulfide tends to improve dispersion of other additives in the rubber.

Crosslink Type: para tert amylphenol disulfide promotes mono-sulfidic crosslinks resulting in vulcanizates with excellent heat and aging resistance.

Non-nitrosamine: para tert amylphenol disulfide 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
