Medical Simulation Silicones - Premium Materials for Realistic Training Models
Medical simulation silicones are specially selected platinum-cured silicones that allow you to create realistic organs, skin, practice mannequins, and medical phantoms. In this category, you will find only products suitable for medical training materials, such as practice skin for suturing, wound and puncture models, organs and tissue blocks for cutting and dissection training, and phantoms for imaging with ultrasound, CT, or MRI. The materials are skin-friendly for external use, have high tear strength, and can be adjusted in hardness and appearance to the desired tissue type.

Zhermack SFX Series - Biocompatible & Flexible
For biocompatible and highly flexible effects, Zhermack SFX 00-20 and SFX 00-30, as well as SkinForm bodycasting silicone, are suitable for replicating thin skin layers, lips, eyelids, and flexible flaps. These products are developed for skin contact and are widely used in special effects and medical training materials, especially when repeated stress from cutting, suturing, and tearing apart is important.
Wacker Addition Transparent - Transparent Models
For transparent or translucent models, such as vascular phantoms or blocks where you want to see internal structures, Wacker Addition Transparent 15 Normal, 15 Fast, 40 Normal, and 40 Fast provide a good basis to work with.
Silicone Foams - Lightweight Organs & Body Parts
For lightweight but voluminous organs and larger body parts, silicone foams are very interesting. With them, you can create a soft, compressible core, which you can then cover with a thinner skin layer of, for example, Wacker FX or another soft silicone. This way, you combine lightweight, resilience, and realistically feeling outer layers.
- Silicone Foam Open Cell 6
- Silicone Foam Open Cell 7 - Spreadable
- Silicone Foam Closed Cell 2
- Silicone Foam Closed Cell 3
- Silicone Foam Closed Cell 3 - Spreadable
- Silicone Foam Closed Cell 5
- Silicone Foam Closed Cell 6 - Spreadable
SAM Deadener 1000 - Softer Tissue Feel
With SAM Deadener 1000 you can reduce the rubbery rebound of platinum silicones, making the material feel more like soft tissue rather than technical rubber.

Wacker Elastosil M 4600 A/B is FDA 21 CFR 177.2600 & BfR XV certified (food safety), which is a good indication of skin-friendliness. Shore A 20, very soft and flexible, perfect for training phantoms and anatomical models.
Polytek PlatSil Gel Series - Worldwide Film Standard
Polytek PlatSil Gel grades are used worldwide for prosthetics, practice skin, organs, and surgical phantoms. By combining these gels with suitable thinners, softeners, and deadeners, a very wide range can be created, from extremely soft fatty tissue to firmer muscle or scar structures.
- PlatSil Gel-OO: Shore 00 - Extremely soft, ideal for fatty tissue, soft organs, and skin layers requiring maximum suppleness
- PlatSil Gel-0020: Shore 00-20 - Ultra-soft for prosthetics and realistic skin layers

Polytek PlatSil SilFoam - Lightweight Cores
Polytek PlatSil SilFoam is a platinum silicone foam often used as a lightweight core behind PlatSil Gels, ideal for organs and limbs that need to be voluminous but not too heavy.
Wacker Elastosil FX Gel 30
From Wacker's FX line, in addition to the well-known FX 10 and FX 20, gel-like variants such as ELASTOSIL FX Gel 30 are also available. These gel factors are useful as a subcutaneous layer or as filled pockets in training models when a more gelatinous feel is desired.
🔬 Application Areas
Surgical Training:
- Suture pads - combine a firm core with a soft top layer
- Incision practice - materials that cut smoothly
- Laparoscopic training - advanced organ models
- Dissection training - tissue blocks with realistic layers

- Organs - use foams for lightweight cores with realistic skin layer
- Blood vessels - transparent silicones for vascular phantoms
- Muscles - medium soft silicones as dermis
- Skin - FX, True Skin, Stretch FX or Zhermack SFX
Puncture & Injection Training:
- Venous access - material with sufficient resistance that closes neatly

🏗️ Layered Construction - Best Practices
When designing medical training materials, a layered construction is often the most realistic:
- Core: Relatively firm platinum silicone or plastic, possibly combined with silicone foam
- Middle Layer: Medium soft silicone as muscle or dermis
- Outer Skin: Soft layer of Wacker FX, True Skin, Stretch FX, SAM Soft Flex or PlatSil Gel
Examples:
- Suture pads: Firm core + thin soft top layer that cuts smoothly but is stable enough to hold sutures
- Organs: Lightweight foam core + medium layer + realistic outer skin
- Puncture models: Material with sufficient resistance when inserting a needle that then closes neatly
📊 Imaging Phantoms - Technical Approach
For medical phantoms for ultrasound, CT, or MRI, you typically start with a transparent or translucent platinum silicone such as Wacker Addition Transparent or a clear Polytek PlatSil Gel. By carefully adding fillers and pigments, scattering, damping, and color can be matched to the target tissue. The silicone itself then provides the elastic, chemically stable, and dimensionally accurate matrix material, while the fillers determine the specific imaging properties.
⚙️ Processing & Technical Properties
All silicones in this category are addition-curing with a platinum catalyst, usually in a mixing ratio of 1:1 or 100:10 by weight. They cure at room temperature, shrink very little, and have low odor.
Processing Tips:
- Vacuum degas in a vacuum chamber for bubble-free models
- Use release agents for complex molds
- Accelerated curing possible with heat (70-120°C)
- Work at a temperature of around 20-23°C
- Always make a small test first
Note - Platinum silicone inhibition:
During processing, avoid contact with inhibiting substances such as:
- Sulfur-containing clay
- Certain latex types
- Tin-cured (condensation) silicones
- Certain amine-containing materials
- Use clean mixing cups and tools
🌟 Safety & Certifications
The materials in this category are intended for external applications such as practice mannequins, phantoms, practice skin, and models that come into brief or repeated contact with human skin, but are not intended for implantation or prolonged internal use.
For training models: No specific certification required. All platinum silicones are safe for use in educational environments.
For prosthetics and prolonged skin contact:
- ISO 10993: Biocompatibility for medical use (e.g., Zhermack SFX, True Skin)
- FDA 21 CFR 177.2600 & BfR XV: Food safety certifications that provide a good indication of skin-friendliness (e.g., Wacker M 4600)
For every project, it is advisable to conduct your own tests for skin compatibility according to the guidelines of the institution or client, especially if there is regular intensive contact, such as in skills labs or daily used training materials.
