Superiority
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
