ENA HRi Flow

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
