Medical Simulation Silicone - Premium Materials for Realistic Training Models
Medical simulation silicones are specially selected platinum-cured silicones that allow you to create realistic organs, skin, training manikins, and medical phantoms. This category contains only products suitable for medical training materials, such as training skin for sutures, wound and puncture models, organs and tissue blocks for cutting and dissection training, and phantoms for ultrasound, CT, or MRI imaging. The materials are skin-friendly for external use, have high tear strength, and can be customized in hardness and optics to the desired tissue type.
✓ Why Choose Medical Simulation Silicone?
Realistic Haptics: Natural softness and resistance like real tissue
Wide Hardness Range: From Shore 00-20 (very soft) to Shore A 40 for different fabric types
High Tear Strength: Resists repeated loads from cutting, bonding and pulling apart
Minimal Shrinkage: Anatomically Accurate Reproductions
Platinum-catalyzed: Addition hardening without harmful by-products
Skin friendly: Suitable for external use and repeated skin contact.
🎯 Product Line Overview - Available in Webshop
Wacker Elastosil FX Series - Lifelike Skin & Prosthetics
The Elastosil FX 10 , FX 20 , and FX 28 are designed for lifelike skin and prosthetics, with low to medium shore hardness, excellent detail reproduction, and comfortable stretch. They are ideal for faces, hands, fingers, ears, and other parts of training manikins.
FX 10: Shore A 10 - Ultra-soft for facial prosthetics
FX 20: Shore A 20 - Versatile for general simulation
SAM Silicone Soft Flex 00-35 - Very Soft Structures
For very soft structures, such as subcutaneous fat, abdominal organs or intestines, SAM Silicone Soft Flex 00-35 is a logical choice, as it is very flexible and can be easily deformed without tearing.
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 simulating thin layers of skin, lips, eyelids, and flexible flaps. These products are designed for skin contact and are widely used in special effects and medical practice equipment, especially where repeated stress from cutting, suturing, and pulling is important.
For lightweight yet voluminous organs and larger body parts, silicone foam is very interesting. It creates a soft, compressible core, which can then be covered with a thinner skin layer of material such as Wacker FX or another soft silicone. This combines light weight, resilience, and a realistic-feeling outer layer.
SAM Deadener 1000 allows you to lower the rubbery spring of platinum silicone, making the material even more like soft tissue instead of technical rubber.
🎯 Additional Products - Available on Request
CHT True Skin & Stretch FX - Real Skin Elastomers
CHT's True Skin silicones, such as True Skin 20 and 30, are designed as real-skin elastomers with high stretch and very lifelike bending, ideal for faces, hands, and suture pads. CHT Stretch FX also offers a highly elastic silicone for ultra-thin, highly conformable skin layers and membranes, for example, for models of joints, neck folds, or highly mobile parts of manikins.
True Skin 20 : Shore A 20, soft skin texture with natural transparency
True Skin 30 : Shore A 30, slightly firmer for structural skin layers
Stretch FX: Extreme stretchability up to 1000% for moving skin layers
Wacker Elastosil M 4600 - Food-safe & Skin-friendly
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 such as Gel 10, Gel 25, and the very soft Gel OO variants are used worldwide for prosthetics, practice skin, organs, and surgical phantoms. By combining these gels with suitable diluents, softeners, and deadeners, a very wide range of properties is created, from extremely soft fatty tissue to firmer muscle or scar structures.
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
In addition to the well-known FX 10 and FX 20, Wacker's FX line also includes gel-like variants such as ELASTOSIL FX Gel 30. These gel factors can be used as a subcutaneous layer or as filled pockets in practice models when a more gelatinous feel is desired.
🔬 Areas of application
Surgical Training:
Adhesive pads - combine a firm core with a soft top layer
Incision Exercise - Materials that cut open smoothly
Laparoscopic training - advanced organ models
Dissection training - tissue blocks with realistic layers
Anatomical Models:
Organs - use foams for light cores with realistic skin layer
Blood vessels - transparent silicone for vascular phantoms
Muscles - medium soft silicone as dermis
Skin - FX, True Skin, Stretch FX or Zhermack SFX
Puncture & Injection Training:
Venous access - material with sufficient resistance that closes neatly
Intramuscular injections
Lumbar puncture models
Infusion training
Image formation Phantoms:
Ultrasound - transparent base with fillers for scattering
CT/MRI - silicone as an elastic, chemically stable matrix material
Internal structures - use Wacker Addition Transparent
Prosthetics & Cosmetic Applications:
Facial Prosthetics - FX 10, True Skin, Zhermack SFX
Test prostheses - biocompatible materials
Ears, fingers, hands - FX series with good detail reproduction
🏗️ Layered Build - Best Practices
When designing medical training materials, a layered structure 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
Puncture models: Material with sufficient resistance during needle insertion that closes neatly afterwards
📊 Phantom Imaging - Technical Approach
For medical phantoms for ultrasound, CT, or MRI, you usually start with a transparent or translucent platinum silicone such as Wacker Addition Transparent or a clear Polytek PlatSil Gel. By controlling the addition of fillers and pigments, scattering, attenuation, and color can be tailored to the target tissue. The silicone itself then provides the elastic, chemically stable, and dimensionally stable matrix material, while the fillers determine the specific imaging properties.
⚙️ Processing & Technical Properties
All silicones in this category are additionally cured with a platinum catalyst, usually in a 1:1 or 100:10 by weight ratio. They cure at room temperature, shrink virtually nothing, and have a low odor.
Processing tips:
Venting in vacuum chamber for bubble-free models
Use release agents for complex molds
Accelerated curing possible with heat (70-120°C)
Work at temperatures around 20-23°C
Always make a small test first
Note - Platinum-silicone inhibition:
When processing, avoid contact with inhibitory substances such as:
Sulphur-containing clay
Certain types of latex
Tin curing (condensation) silicone
Certain amine-containing materials
Use clean mixing cups and tools
🌟 Safety & Certifications
The materials in this category are intended for external applications such as training manikins, phantoms, practice skin and models that come into brief or repeated contact with human skin, but are not intended for implantation or long-term internal use .
For training models: No specific certification is required. All platinum silicone models are safe for use in educational settings.
For prostheses 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 compatibility (e.g. Wacker M 4600)
For each project, it's wise to conduct your own skin compatibility tests according to the institution's or client's guidelines, especially if there's frequent, intensive contact, such as in skills labs or with daily practice materials.
