Theming, Display & Décor
Polytek®’s mold making and casting materials are widely used in zoo and museum exhibits, haunted attractions, theme parks, restaurants, retail outlets, hotels, casinos, and other venues to create themed environments, displays and unique décor.
A wide variety of effects and objects can be created using Polytek® materials, including faux glass objects, faux bronze objects, lightweight foam décor and facades, lightweight architectural elements, still figures, signage, life-like silicone displays, realistic scenery and much more.
Once an original design is created by an artist, a flexible polyurethane or silicone mold or rigid plastic mold can be made of the original. A variety of casting materials can then be cast in the finished mold, including plastics, foams, polyurethane and silicone casting rubbers, plaster, concrete and more.
In some cases, and especially in theming and scenic design, foam carvings are hard-coated with a fire-rated plastic shell to provide a durable outer coating which can be easily painted.

Polytek® silicone mold rubbers are most often used when making molds for resin or foam casting. Release agents are generally not needed for either process, which is why they are sometimes preferred over polyurethane mold rubbers. For resin castings that need to be painted after casting, silicone mold rubbers are recommended. Tin-cured (TinSil®) and platinum-cured (PlatSil®) silicone options are both available.
The silicone mold rubbers listed below are pourable, but can be easily thickened for brush-on application when desired. PlatSil® silicones can be thickened with PlatThix Liquid Thickener for brush-on application and TinSil® silicones can be thickened with TinThix Liquid Thickener.

| Product | Description |
|---|---|
A platinum-cured, medium-soft silicone that can be demolded after 1 hour. |
|
A platinum-cured, medium hardness silicone that can be demoded after 4 to 5 hours. It has a longer pour time than PlatSil® 73-20, so is useful for making larger molds. |
|
A platinum-cured silicone that is harder than the previous options and offers great dimensional stability. |
|
A tin-cured, medium hardness silicone with a long pour time of 30 minutes and a demold time of 24 hours. TinSil® silicones have a shorter library life compared to PlatSil® rubbers and also shrink slightly (~1%) on cure. |
NOTE ON CURE INHIBITION: Sulfur-containing clay and other sulfur/tin/amine-contaminated materials and tools will cause cure inhibition in platinum-cured silicone rubbers, which means that the rubber that is in contact with the contaminated surface will remain gummy or uncured. Make sure to test cure the rubber on your surface before full-scale application. Use a polyurethane or tin-cured silicone rubber if you know that you’ll be working with any of these inhibitors.
Polytek® polyurethane mold rubbers are most often used to make molds for casting wax, plaster and concrete. Release agent is generally not required when casting wax and plaster, but is needed when casting most concrete mixes. Resin casting can also be done in polyurethane molds with an appropriate release agent (e.g., Pol-Ease® 2300 Release Agent). Polyurethane molds are economical (less expensive than silicone mold rubbers) and long-lasting.

Thin, brush-on or spray-on molds require a supportive mold shell. Mold shells can be made with a number of materials, including plaster, polyester resin and fiberglass and thickened polyurethane plastic. Polytek® offers strong, fast-setting polyurethane plastics that are widely used in mold shell construction.

PlatSil® Gels are contact-safe, platinum-cured silicone rubbers that are widely used in the special effects industry for creating hyper-realistic props and displays. These silicone gels are often used in conjunction with Deadener; an accessory that helps to remove the synthetic quality of rubber and mimic skin and tissue. |
A NOTE ON CURE INHIBITION: Sulfur-containing clay and other sulfur/tin/amine-contaminated materials and tools will cause cure inhibition in platinum-cured silicone rubbers, which means that the rubber that is in contact with the clay model or contaminated surface will remain gummy or uncured. Make sure to test cure the rubber on your surface before full-scale application.
Plastisol is a versatile material that is often used to make food props and other display items. Unlike the majority of materials listed on this page, Plastisol is not a room-temperaturing (RTV) curing material. Plastisol is a plasticized polyvinyl chloride resin (liquid) that is cured by heat (~350°F) to form a solid product once cooled; therefore, special heating equipment and heat-resistant molds are required.
California Medical Innovations (CMI), a Division of Polytek® Development Corp., has over 35 years of experience in custom formulation and compounding of Plastisol.
Plastisol can be custom-formulated to achieving varying final properties. Some customizable elements include: color (e.g., opaque, translucent, custom color matching), durometer (hardness ranging from Shore A5-D90), texture and finish, resistance properties, and more.
