Polyplank's products are classified as WPC products, which is a wide collective group where material composition between thermoplastic and wood fiber varies greatly. WPC stands for Wood-Plastic Composite.

The United States is the single largest market for WPC products, followed by China, Europe and Japan. The North American market is more mature and has experienced a sharp increase in WPC products. The increase in sales has been pronounced. For example, in 1999 the market for WPC products for decking made up only three percent of the total U.S. market for decking; today, the market share of WPC products stands for over 30 percent of the total decking.

One of the reasons that the market for WPC products is more developed in the U.S. relative to other major markets is partly explained by the ban imposed on the use of the toxins copper, chromium and arsenic (CCA toxins) to impregnate wood in 2003.

The European market for WPC products has grown strongly in recent years. The same ban on CCA toxins to impregnate wood, which the U.S. introduced in 2003, was introduced in 2006 for consumers in Europe, followed by a general ban in 2008. The toxins have proved difficult to replace if the impregnating quality of the timber shall be maintained. It also prohibits the importation of CCA-treated wood into the EU.

Currently, Polyplank's priority market is Scandinavia. The Nordic market is still in its infancy. The products are mainly flooring for outdoor use, railings and fences. Today, WPC material is replacing mainly impregnated timber, where properties of the material such as low maintenance as well as moisture and mold resistance are valued by WPC producers' customers.
