Technical Properties :

STRUKSILON 8026 was specifically designed to be used in shoe sole and other microcellular systems. It is mainly recommended for polyester and polyester/polyether blend based formulations. STRUKSILON 8026 offers an excellent regular and fine cell structure and a good skin formation. Even in low density foams skin defects and voids on or slightly under the surface can be avoided. Very low shrinkage will be observed even at short demould times using low-density formulations.
Due to this outstanding performance STRUKSILON 8026 is recommended as a wide density range silicone surfactant for all polyester polyol based shoe sole applications in formulations from 0,34 g/cm3 to 0,58 g/cm3.

Recommended Dosage

Usually, STRUKSILON 8026 is applied in quantities of 0.1 to 1.0 php (parts on 100 parts polyol). We recommend adjusting the optimum dosage to the corresponding formula. However, a concentration of 2 php should not be exceeded.

Product Safety and Handling

STRUKSILON 8026 is not a hazardous material for the purposes of hazardous materials regulation.
