Physical Properties

A - DENSITY

Chemcrest Inc. products are made with high-density polyurethane foam with an overall core density similar to White Pine at between 10 and 19 lb. per cubic foot. Chemcrest Inc.’s manufacturing process provides a greater skin density than core density, which increases durability.

B - SURFACE PROPERTIES AND FINISHES

All products are produced incorporating a white or tan/wood color barrier coating. In addition to this integral barrier coat, all products receive a primer coat with built-in UV inhibitors. The combination of the integral shell-like skin, the barrier coat, and the primer top coat provide an excellent substrate for durable finishes.

C - ULTRA VIOLET

Ultra Violet rays do not affect properly coated polyurethane products.

D - COMPRESSIVE STRENGTH

Falls within the 300 – 400 P.S.I. range.

E - TENSILE STRENGTH

Falls within the 350 – 400 P.S.I. range.

F - FLEXUAL STRENGTH

The degree of flexibility in any given polyurethane product is determined by the shape and size of its cross section. Due to the inherent flex characteristics of lineal footage products, they will follow some curvature and uneven surfaces.

G - MOISTURE RESISTANCE

Chemcrest Inc. polyurethane has a closed cell structure which provides protection from the environment and renders it almost completely moisture resistant.

H - MILDEW RESISTANCE

All Chemcrest Inc. polyurethane products are mold and mildew resistant and cannot be harmed by termites or other insects or rodents.

I - FLAMMABILITY

All polyurethane materials are combustible when exposed to open flame – as all wood materials are.

J - SHRINKAGE

All polyurethane materials will expand and contract nominally depending on environmental factors such as temperature and humidity. Chemcrest installation instructions and polyurethane based adhesive recommendations are available to best address shrinkage and must be used in order not to void warranty.
