Polyvest

Refractory Die Material

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
