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
