Construction & Architecture

Innovative Polymers manufactures rigid polyurethane foams as well as polyurethane casting systems that are ideal for building high-accuracy, durable architectural models. Our products are also well suited for building architectural-quality decorative details such as balustrades, crown moldings and millwork. Used as an economical, low maintenance alternative to carved wood, polyurethanes do not rot, splinter or crack and replicate the most intricate details for high quality construction.

Innothane® liquid urethanes for architectural models include:

4 lb. – and 6 lb.-density materials formulated for hand-batch or meter mix dispensing. Formulated without mercury, MOCA or TDI, the products cure at room temperature and can be de-molded in less than 15 minutes. Light tan in color, the foams are easy to paint.

Designed for hand batch mixing and pouring.  They can be cast over steel or brass inserts required for added strength or aesthetics.  The polyurethanes feature:

• Ultra-low viscosity
• Easy to handle 1:1 mix ratio by volume
• Rapid gel time of <10 minutes at room temperature
• Demold time of 10 minutes to 1 hour
• Shore hardness from 70D – 80D +/-5
• Tensile strength of 4,950 psi to 10,500 psi
• Flexural modules values ranging from 175,000 psi to 420,000 psi

These materials are paintable and are tough enough to withstand handling and shipping without breakage, and for architectural details, the polyurethanes can be exposed to weather and temperature extremes without deforming.
