XCEM Polyoxal-HB is a high-performance Heavy Body Polyvinylsiloxane (PVS) Addition Silicone Impression Material specifically developed for precision impression procedures in restorative and prosthodontic dentistry. The material is supplied as Base and Catalyst pastes that are hand-mixed to produce a homogeneous consistency with excellent handling properties.

Its heavy-body viscosity provides outstanding tray support while maintaining excellent dimensional stability and low polymerization shrinkage. The material exhibits superior tear strength, excellent elastic recovery, and precise reproduction of fine anatomical details, ensuring highly accurate impressions for indirect restorations.

Polyoxal-HB is ideal for putty-wash techniques, one-step and two-step impression procedures, implant restorations, crown and bridge work, veneers, inlays, onlays, and full-mouth rehabilitation. Its excellent stability allows impressions to retain their accuracy until model fabrication, providing reliable clinical and laboratory outcomes.
