Polyurethane Materials

Polyurethane Plastics: Rigid & Semi-Rigid

Use Polytek® polyurethane casting resins to create rigid and semi-rigid props. From fast-setting resins to water-clear options, almost any color, size, shape, weight and appearance can be achieved by using these systems.

Polyurethane Foam Football

Polyurethane Foam

Polyurethane foam is often used to produce lightweight props and decor. It can also be used to backfill other casting materials, such as polyurethane plastic, polyurethane rubber and silicone rubber.

Polyurethane Rubber

Polyurethane rubbers can be used to make flexible molds to cast multiple copies of one object, or can be used to cast flexible props. While all polyurethane rubbers can be used to cast parts, the PT Flex Series is very popular because of their low-viscosity mixes, simple 1A:1B mix ratios and fast demold times.

Silicone Materials

Silicone Rubber

Silicone rubbers can be used to make flexible molds to cast multiple copies of one object, or can be used to cast flexible props. Silicone molds are most often used when making molds for resin or foam casting as release agents are generally not needed for either process.

Silicone is also an excellent material for animatronic skins.

PlatSil® SiliGlass

PlatSil® SiliGlass is a platinum-cured silicone designed for making super-clear, glass-like rubber castings for special effects and prop applications. SiliGlass is designed to act and look like broken glass when hit. 

Silicone Foam

PlatSil® SiliFoam is a platinum-cured silicone foam with a 15 lb/ft³ density. Often used in conjunction with PlatSil® Gel Silicone Rubbers to create realistic props.

Latex Materials

Latex Rubber

NaturForm™ Mask Making Latex Rubber is designed to be poured into a dry, unsealed Gypsum plaster mold and air dries to form a high-strength, flexible casting. Natural latex rubber is one of the most popular materials for making novelty Halloween masks, prosthetic appliances, haunted attraction props, and animatronic skins.

Epoxy Materials

Casting Epoxies

PolyPoxy® Casting Epoxies are aluminum-filled, heat-resistant, room temperature curing (RTV) systems that are typically used for heat-resistant vacuum form tools, injection and compression molds, RTM and RIM molds, and matched dies.

Laminating Epoxies

PolyPoxy® Laminating Epoxies are low viscosity, room temperature curing (RTV) systems formulated for general purpose and high-temperature fabrication applications.

Surface Coating Epoxies

PolyPoxy® Surface Coat Epoxies are thixotropic, room temperature curing (RTV) systems formulated for the fabrication of general purpose or heat-resistant laminated tools, including dies, foundry patterns, core boxes, and router, trim and inspection fixtures.

Epoxy Adhesives

PolyPoxy® Epoxy Adhesives are two-component, room-temperature curing (RTV) systems designed to be used as general-purpose adhesives as well as a bonding adhesive for TekBoard™ Tooling & Modeling Board.
