Testing Data
UV Resistance:
In an environment chamber exposed to UV light, moisture, and chemicals
for approximately 2000 to 2500 hours, the sample exterior (approx. 1mm) was mildly
bleached. The sample was still hard and resilient below the surface with no other
visible damage. Most wood samples including treated ones would show signs of
severe degradation.
Deflection:
Heartland’s product contains recycled HDPE. Under certain circumstances, depending upon climate, environment and topography Heartland’s products may “deflect” or expand, which is beyond the manufacturer’s control. Adding a fourth backer rail, PrairieRail™, will help counter this natural occurring phenomenon. Please contact Heartland’s customer service department to speak with a technical advisor regarding deflection questions and concerns.
Color:
Heartland BioComposites product is naturally light to dark brown and can be
dyed in the production process virtually any color. Based on color retention
tests per ASTM D-4329, Heartland's composites retain color up to 50% better
than typical wood-plastic composites. Delta E of 11.54 (Heartland) compared
to 16.0-20.0 (wood-plastic composites) at 2,500 hours.
Cost:
Our product is typically cheaper than other commercially available composites.
Strength:
Heartland's composite is stronger than commercially available wood-plastic
composites based on information available in the public domain.
Strength Tests: Heartland's Composite vs. Leading Competitors **Note:
Tensile is a measure of "breaking strength"
**Note: Modulus of elasticity is a measure of "stiffness."
