Crown Molding Material Specifications

Polyurethane

First Class Building Products, Inc. products are made with high density polyurethane with an overall density similar to white pine at 13 to 17 pounds per cubic foot. The First Class Building Products, Inc. process provides a greater skin density than core density for increased durability.

All products are manufactured with a white or beige color coating. Further, these products receive a primer coat finish before they are shipped to customers. the combination of the integral shell-like skin, the barrier coat, and the primer top coat provide an excellent substrate for durable finishes.

Ultra violet rays do not affect properly coated products.

The compressive strength of polyurethane products falls within the 300-400 P.S.I. Range. (The parts are not intended for structural use.)

The tensile strength of polyurethane products falls within the 350-400 P.S.I. range. (The parts are not intended for structural use.)

The degree of flexibility of any given polyurethane product is determined by the size and shape of its cross section. However, due to the inherent flex characteristics of polyurethane products, they will follow some curvatures and uneven surfaces.

First Class polyurethane has a closed cell structure which provides protection from most solvents and renders it almost completely hydrophophic. It will not rot!

All First Class polyurethane products resist the growth of mildew and fungus and further provide no nutritional value for other organisms such as small rodents.
