Specification

Application:

the composition for bleaching agent for rosin ester is alkylphenol disulfide polymer.it is a kind of multifunctional agents for rosin and rosin esters. 

• excellent bleaching agent in the disproportionation of rosin or rosin esters.it reduce the color of gum rosin and gum rosin ester greatly.

• excellent antioxidant in the disproportionation of rosin or rosin esters. It improve the heat resistant and light resistant ability of the gum rosin and gum rosin ester.

• excellent catalysts in the disproportionation of rosin or rosin esters. It can make the reaction more quick.

• excellent stabilization agent in the disproportionation of rosin or rosin esters.it can make the gum rosin and gum rosin ester more stable under the light and heat exposure for long term

Advantages:

• reduce color greatly with low dosage

• better color stability

• Non-nitrosamine;environement -friendly

• Lower tack to make it easier to stock and handle

• Lower volatility

• Lower volatile degradation products

• Very good antioxidant properties

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