Applications:
It is an excellent emulsifier for polymerization and copolymerization of some unsaturated compound such as acrylate, propylene, butadiene, styrene and chloroethene. High concentration and high stability emulsion without agglomeration can be obtained with a little dosage of 0.2%-3.0%. It can also be used as emulsifier for natural rubber latex, synthetic rubber latex and plastisol dispersion (like polyacrylate emulsion).

It is an ideal emulsifier for polyacrylate emulsion with high content of 45%-50%. It can be use in both continuous emulsion polymerization process and batchwise emulsion polymerization process to get fine and even emulsion particle and stable emulsion and emulsion matrix system.

Due to its excellent dispersibility, the emulsion matrix has good anti-shearing force in E-PVC manufacture process to get stable polymerization and avoid adhesion and deposition of emulsion particle onto the surface of the reactor.

It will not be radical scavenger and quencher as there is no double bond in the structure, which also ensures the duplication and continuing of the emission polymerization with a maximum limit.

Low concentration sulfate and good thermally resistance of the final product can be ensured by the less dosage and even polymerization.

It can be directly used in the polymer as an anti-static agent with its good anti-static property.

Used as raw materials for other emulsifier for emulsion polymerization, especially for pressure-sensitive adhesive, plate alignment adhesive and counter resin.
