Why Dur-A-Sil® Equal Outperforms Traditional Impression Materials

Low Shore A (20 Durometer) & Superior Elongation

Formulated to a cushiony soft Shore A hardness of only 20, combined with high stretchability and excellent release properties. Ensures painless removal from the bony portion of the ear canal or irregular ears, resulting in significantly less “red ear” and superior patient comfort.

Lower Viscosity for Distortion-Free Injection

Syringes with lower resistance, placing minimal pressure on delicate canal walls and eliminating artificial ear canal distortion during injection.

Zero Sagging (Thixotropic Control)

Excellent thixotropic properties ensure the material stays exactly where placed without slumping, sagging, or shifting while curing.

Fast 5–7 Minute Cure

Cures quickly into a durable, stretchable rubber in just 5 to 7 minutes, speeding up clinical workflow and minimizing patient chair time.

Exceptional Memory & Zero Shrinkage

Features outstanding dimensional stability with virtually zero shrinkage over time, delivering distortion-free memory for flawless laboratory scanning and reuse.

Transit Durability & Remake Confidence

High tear resistance and stability give clinicians complete confidence that impressions will survive shipping intact and allow manufacturers to reuse impressions without costly remakes.
