Soft–Hard Bonded Sheet Technology
🔹 Overview
Kalivon Dual is engineered to bridge comfort and strength through an advanced two-layer co-extrusion system.
By combining a soft inner bonding layer with a rigid outer surface, it offers exceptional flexibility on the tissue side and high durability on the occlusal surface.
This dual-layer structure provides optimized thermoforming behavior, improved adaptation to tooth morphology, and enhanced patient comfort without sacrificing stability.
Kalivon Dual is ideal for retainers, splints, night guards, and snoring appliances, where both resilience and comfort are equally important.
⚙️ Technical Specifications
| Property | Description |
|---|---|

| Applications | Retainers, Splints, Aligners, Snoring Appliances |
🧬 Technology Insight
Kalivon Dual utilizes a precision co-extrusion process that molecularly bonds PETG and TPU layers into a single integrated sheet.
This permanent interface ensures that the material will not separate or bubble during heating and forming, unlike conventionally laminated films.
The result is a material that combines rigidity, elasticity, and biocompatibility in perfect balance.
