Environmentally sustainable product protection
Wood plastic composites (WPCs)—a combination of wood and plastics—are a safe, environmentally sustainable, and long-lasting material for use in outdoor decks, fences, railing and window frames. Found everywhere from national parks to your own backyard, WPCs offer a wide range of advantages, including weather resistance, long service life, and lower maintenance. These products also play a role in developing a more sustainable future: Many WPCs use recycled plastic and wood as raw materials in the manufacturing process.
Unfortunately, unprotected wood fiber in WPCs can be susceptible to destructive organisms, such as decay fungi. With a typical wood-to-plastic ratio of 50:50, fungi can destroy 20-40% of WPCs’ wood component. To provide affordable, long-lasting protection of WPCs against decay fungi, consider preservation with borates as a wood fungicide.
