Polyurethane Materials

Polyurethane Plastic: Rigid & Semi-Rigid
Use Polytek® polyurethane casting resins to create a number of finished objects and décor. 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
Polyurethane foams is often used to produce lightweight objects, props, architectural elements and décor. They can be used to make finished parts, but are also used to back all other casting materials, such as polyurethane plastic.

Polyurethane Rubber
Polytek® manufactures a high-quality line of two-part, room-temperature curing (RTV) polyurethane rubbers that can be poured, brushed or sprayed to make molds or flexible parts. Polyurethane rubbers are most often used to make molds for casting wax, plaster and concrete.
Silicone Materials

Silicone Rubber
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.

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 prosthetic appliances and props.
Epoxy Materials

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

Surface Coat 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.

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.

Epoxy Clays
PolyPoxy® Epoxy Clays are two-component, room temperature curing (RTV) systems. When mixed together, these components form a soft, dough-like consistency that cures to a hard solid with excellent toughness and dimensional stability.

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.
Board Materials

Polyurethane, Aluminum-Filled & Epoxy Tooling & Modeling Board
TekBoard™ Tooling & Modeling Boards are pre-fabricated, highly machinable, dimensionally stable block materials that assist engineers, model makers, mechanical designers, and prototype developers in meeting the demanding needs of the aerospace, automotive, modeling, and prototyping industries.
