Foam & Plastic Millwork & Ornamentation

PolyFoam Casting FoamPolytek® two-part polyurethane foams and polyurethane resins are used to cast a wide variety of decorative millwork and architectural decor elements which can be used in both interior and exterior environments (parts must be painted for use outdoors).

In addition to PolyFoam rigid casting foam, Polytek® also offers flexible and rigid plastic casting materials. Poly Plasti-Flex is a slightly flexible polyurethane plastic often used to produce decorative trim molding and millwork. EasyFlo 60 Liquid Plastic, a fast-setting rigid polyurethane plastic, can also be used for decorative parts that do not require flexibility.  

Platinum-cured (PlatSil®) and tin-cured (TinSil®) silicone mold rubbers are most often used to cast these polyurethane foams and plastics as they have excellent release properties and hold up well to the rigors of production.
