Water absorption to WPC material is slow, and it is characteristic that it occurs mainly at the .. There are also studies indicating lack of long term durability of WPCs, including fungal decay and Long-term water absorption and dimensional stability of composites .
The composite materials were manufactured into panels by a twin-screw extruder. Long-term water absorption (WA), long-term thickness swelling (TS), and degradation of flexural properties of the composites were studied for a range of water immersion times. The WA and TS of the samples increased with RWF content and immersion time.

Watersorption - Water absorption of Wood Plastic Composites. Analysis of the water absorption in Wood Plastic Composites (WPC) in order to develop solutions to decrease and stop water absorption.
To simulate long-term field impact (including decay) on WPC flexural properties in the laboratory, conditioning of specimens in hot water for an extended period of time is required.
Water absorption study was performed following the ASTM D 570-98 method. Water absorption of the composites was determined after 2 h, 12 h, 24 h until 2-month immersion in distilled water at room temperature, 24°C. Five specimens of each formulation were dried in an oven for 24 h at . The dried specimens were weighed with a precision of 0.001 g.
The long term water absorption by total immersion is not directly related to the conditions on site, but has been recognized as a relevant condition of test for some ... In WPC manufacturing, virgin plastics are commonly used.

Water absorption of WPC materials mainly depends on fiber volume fraction, orientation of fibers, exposed surface area, and temperature . It can be assumed that wood flour is solely responsible for water absorption by the WPC material considering the fact that polypropylene is water repellent and does not swell in water .
The long-term water absorption of the composites was evaluated by their immersion in water at room ... for decking, flooring and outdoor facilities, window ... composite water proof deck - wpc floor manufacturer
Water absorption (WA) studies were performed following the ASTM D 570 standard. The water absorption of the WPC specimens was determined after 2, 24, 72, 168, 240, 432, 624, 768, 912, and 1056 h immersion in distilled water at room temperature.
