More Facts from Impression Materials — Detailed Properties

Addition silicone PVS = most accurate no byproduct

Condensation silicone = releases alcohol byproduct = shrinkage

Polysulfide = longest setting time messiest = lead dioxide accelerator

Polyether = stiffest most hydrophilic = initial rigidity

Alginate = irreversible hydrocolloid = snap set

Agar = reversible hydrocolloid = high detail low strength

Impression plaster = most rigid.
