King StarBoard® ST is a special, high-density polyethylene sheet that provides a super tough surface for many King StarBoard® applications that last a lifetime
Now Available for Upgrade with King FlameShield for our ASTM E-84 Class A or B Flame/Smoke Compliance and CAN/ULC-S102 for Canadian Compliance
King StarBoard® ST is a special, high-density polyethylene sheet that provides a super tough surface for many King StarBoard® applications. A unique and advanced polymer makes the material 25% stronger than the original King StarBoard®. High scratch-resistance makes it especially appropriate in the construction of cabinets and furniture. Also, its high strength and stiffness make it desirable for applications where less structural support is available. King StarBoard® ST is environmentally stabilized and has been developed to withstand the harshest outdoor conditions. It can be used in wet areas that need to be washed often for cleaning, or are regularly exposed to moisture. It can be fabricated using common woodworking tools and techniques.
