Advantages of Potassium Disproportionated Rosinate:

1.Outstanding emulsification stability

It serves as an essential emulsifier in the emulsion polymerization of styrene-butadiene rubber (SBR). It can form stable and fine micelles, enabling uniform dispersion and polymerization of styrene and butadiene monomers in water.

2.Favorable chemical stability

The disproportionation process eliminates active double bonds, endowing it with superior oxidation resistance and color fastness compared with superior disproportionated potassium rosin soap. It will not cause interfering side reactions in the polymerization system.

3.Moderate surface activity and foamability

Beneficial to rubber product performance

During the post-treatment of synthetic rubber, the residual potassium disproportionated rosinate exerts minimal impact on the aging resistance and mechanical properties of rubber, and even offers certain benefits.

Biodegradability

Derived from natural rosin, it is environmentally friendly..
