Flowable Composite - “No Bubbles” Formulation

Standard flowable composite formulations incorporate fine air bubbles into the material. When photo-polymerized these air spaces result in uncured composite internally, leading to internal structural weaknesses and the development of micro-fractures. The ENA HRi Flow formulation eliminates air bubbles, resulting in superior physical properties.

  • Highly Filled (77%)
  • Higher Viscosity & Modulus of Elasticity
  • Higher Radiopacity
  • Superior Physical Properties
