Application:
① Alkylphenol disulfide polymer is an excellent bleaching agent in the disproportionation of rosin or rosin esters.it reduce the color of gum rosin and gum rosin ester greatly.
② Alkylphenol disulfide polymer is an 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.
③ Alkylphenol disulfide polymer is an excellent catalysts in the disproportionation of rosin or rosin esters. It can make the reaction more quick.
④ Alkylphenol disulfide polymer is an 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
⑤ Alkylphenol disulfide polymer is an excellent vulcanization agent for vegetable oils.
Advantages:
① Non-nitrosamine;environment-friendly
② Lower tack to make it easier to stock and handle
③ Lower volatility
④ Lower volatile degradation products
⑤ Very good antioxidant properties
⑥ Improve heat age of vulcanizates because of its generation of mono- and di-sulfic crosslinks
