product description
YETI EXPANSION Plus II (3D) – Precision Investment Material
YETI EXPANSION Plus II (3D) is a fine-grained, phosphate-bonded precision investment material for crown and bridge work. It features maximum possible expansion, making it ideal for non-precious metal alloys (NEM) and pressable ceramics. It offers flexible application using either the rapid speed heating process or the traditional step-by-step heating procedure.
Your Advantages at a Glance:
- Maximum Expansion: Precise control for optimal fit in non-precious alloy restorations and pressable ceramics.
- Flexible Processing: Suitable for speed burnout as well as conventional step heating.
- Excellent Flowability: Fine-grained consistency ensures detailed reproduction.
- High Compressive Strength: Ensures stability and reliability during casting.
Technical Data & Properties
| Working time (21–24 °C) | approx. 6 minutes |
| Mixing time under vacuum | 50 seconds |
| Setting expansion | 2.40 % |
| Flowability | 13 cm |
| Compressive strength | 7.5 MPa |
| Total setting time | 15–20 minutes |
Recommended Mixing Ratios (160 g Powder)
Note: Total liquid volume per 160 g powder is 38 ml. Expansion is controlled via the ratio of mixing liquid to distilled water.
| Application / Alloy | Liquid | Dist. Water |
|---|---|---|
| Precious Metal Alloys | 9 ml | 29 ml |
| Palladium-Based Alloys | 19 ml | 19 ml |
| Co-Cr Bonding Alloys | 27 ml | 11 ml |
| Ni-Cr Bonding Alloys | 24 ml | 14 ml |
| Pressable Ceramics (Inlay / Veneer) | 19 ml / 22 ml | 19 ml / 16 ml |
| Press over Metal (PoM - Speed only) | 24 ml | 14 ml |
Processing Instructions
- Speed Burnout: After 20 minutes setting time, the muffle can be placed directly into the preheated furnace (suitable for muffle sizes X1 to X6).
- Final Temperatures:
- Gold alloys: 700–750 °C
- Bonding alloys / Pressable ceramics: 800–850 °C
- Non-precious metal alloys (NEM): 900 °C
- Storage: Store dry at room temperature (~21 °C). Protect liquid from frost (< 5 °C causes loss of usability). Shelf life: 24 months.
Safety Note: The investment material contains reduced amounts of quartz[cite: 1]. Avoid breathing dust. For professional dental technology use only.
