Conclusions Wood Plastic Composites (WPC) boards absorb a
significant quantity of water during exterior exposure. Moisture
content distribution in the board cross-sections have a
characteristic U-shape, frequently exceeding the concentration
required for decay initiation.
A major factor in water absorption by WPC was the ratio of wood
to plastic binder
Another factor in water absorption is the material composition
of WPC. Certain additives may significantly increase or decrease
water absorption (for example zinc borate decreased water
absorption in the tested formulations)
Water absorption is a long process, and even after 6 years
exposure in a moderate climate, equilibrium has likely not been
reached
Climate and sample location (sun or shadow) may not be a major
factor in water absorption
It was shown that water absorption in exterior exposure most
likely influenced MOE of selected samples (decrease ~30%). It was
observed that some experimental samples with a significant amount
of water absorption underwent decay in exterior exposure.
