How Is Particle Board Made? Why Water Can Ruin It

Why does particle board swell when wet, and why doesn't it always shrink back after drying? The answer lies in how particle board is manufactured and what happens to its internal structure when water gets inside. Particle board is found in kitchen cabinets, bookshelves, desks, and countless pieces of affordable furniture. Made from wood particles bonded with resin under heat and pressure, this engineered wood can remain strong for years. But moisture can cause swelling, weaken the internal bonds, and leave permanent damage. In this video, we'll explore how particle board is made, how factories transform wood scraps into solid panels, and why water can permanently change their structure. You'll also discover why particle board screws can loosen, why shelves begin to sag over time, how moisture-resistant boards differ from ordinary panels, and what separates particle board from MDF and OSB. From wood scraps to the furniture inside your home, particle board has a surprisingly fascinating story. Have you ever had a cabinet swell after a water leak or a bookshelf start to sag?
