Application:
Bleaching agent OF-TB7 is alkylphenol disulfide polymer. It is a multifunctional agent for gum rosin and the derivates:
· Excellent bleaching agent in the disproportionation of rosin or rosin esters. It reduces greatly the color of gum rosin and gum rosin ester.
· Excellent antioxidant in the disproportionation of rosin or rosin esters. It improves the heat resistant and light resistant ability.
· Excellent catalyst in the disproportionation of rosin or rosin esters. It speeds up the reaction.
· 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.
· Excellent vulcanization agent for vegetable oils.
Advantages:
· Non-nitrosamine, environement -friendly
· Lower tackness to make it easier for stock and handling
· Lower volatility
· Lower volatile degradation
· Excellent antioxidant properties
· Improve the heat-ageing property of the vulcanizates by its generated mono-di-sulfic crosslinks
