Polyvest Refractory Die Material is formulated with a coefficient of thermal expansion to closely match today’s newer porcelains. With its controlled expansion, Polyvest permits full contour build-ups and produces accurate ceramic restorations.

Polyvest offers many advantages to users such as:

  • Ample working time to pour models
  • Fine-grained material with fluidity for highly accurate reproduction
  • Highest strength to resist fracture and abrasion
  • Controlled expansion to match most porcelains (CTE 13.9 or below)
