Application:

①　Description:Amylphenol disulfide polymer 3 is nitrosamine-free sulfur donor vulcanizing agent.

②　Polymers: Natural rubber and most synthetic rubbers.

③　Crosslink Type:Amylphenol disulfide polymer 3 produces predominately monosulfide bridges. These bridges are stable and have excellent resistance to heat and ageing when compared with typical polysulfide bridges.

 

Advantages:

①　Non-nitrosamine

②　Lower tack to make it easier to stock and handle

③　Lower volatility

④　Lower volatile degradation products

⑤　Good compatibility with many rubber polymers

⑥　Very good antioxidant properties

⑦　Improve heat age properties of vulcanizates because of its generation of mono- and di-sulfic crosslinks

⑧　Increase the resinous plasticizer during processing

⑨　Increase the green tack in NBR,BR and SBR based compounds

⑩　Improve the dispersion of other compound ingredients into rubber
