Water resistance of wood-plastic composites

WPC (Wood Plastic Composite) is the main material of Outdoor WPC Decking. how does wood plastic become an indispensable part of our lives step by step?

Due to the increased awareness of environmental protection, the development of these conforming materials made of natural fibers has received widespread attention, thus forming our current WPC. Waterproof and moisture-proof is one of the biggest advantages of WPC. Due to the unique application range of WPC Decking, courtyards, balconies, terraces, poolside, parks and other areas. Basically, they deal weather-beaten, so WPC can replace solid wood. It fundamentally solves the problem that wood products are easy to rot, swell and deform after absorbing water in a humid and watery environment. Its service life and later maintenance cost far exceed real wood.

WPC is a combination of different grades of plastic (virgin and recycled) and amounts of wood flour. Polyethylene obtained from selective packaging waste collection was used as a matrix, and the preparation process was in two stages – mixed and injection. Finally made into different shapes of WPC Decking and Cladding. Due to the raw materials, WPC finally has the characteristics of wood and plastic at the same time.

How to appraise the waterproof performance of Composite Decking?

The waterproof performance of WPC decking depends on the foaming rate of related materials, whether the foaming rate can reach about 10%, in the case of water absorption, whether water absorption will cause the change of length, and how wide the change of width can be controlled.

The last little trick, Identify whether the quality of the WPC Decking you purchased is up to standard? Take a small piece and boil it in boiling water at 100 degrees Celsius for 24 hours, then you test the adhesion of the WPC Decking. Generally, products with too high wood flour content are easy to decompose after testing, and the adhesion is not high, and the quality of long-term use also has problems.
