Phenyl PEG POSS® Heterocage

Supplied byHybrid Plastics- Last Updated on Jun 9, 2026

Phenyl PEG POSS® Heterocage by Hybrid Plastics is a plasticizer and wetting agent. It is a hybrid molecule with a rigid inorganic silsesquioxane at the core and organic phenyl and PEG groups attached at the corners of the cage. It is a rheological diluent which lowers the viscosity of high-solids systems. It is a molecular union of both functional chemistry and inorganic-organic compositions. Provides gloss effect, mechanical strengths, high temperature stability and dispersion through pi-pi interactions.
  • It reduces agglomeration, improves uniformity and increases surface hardness.
  • It improves toughness, oxidative- and impact resistance without sacrificing clarity.
  • It improves interfacial bonding to metals, glass, and polymers/resins.
  • Phenyl PEG POSS® Heterocage is compatible with a wide range of resins and monomers bearing similar chemical functionality.
