HDPE ColorCore® Sheet is environmentally stabilized high-density polyethylene which 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. Its thin cap layers and bright primary colors make it ideal for signage, marine, playground and recreational applications. For maximum versatility, standard colors are made to coordinate with King ColorBoard®. We have improved King ColorCore® so it is now easier than ever to engrave. We have made the cap consistent in thickness for all three gauges of King ColorCore®, for a very uniform appearance. So when your project calls for different gauges of material, you can be confident the at your engravings will have the same quality look from sheet to sheet. Base materials are FDA approved as are most pigments. It is made with high-impact-resistant polymer to handle more abuse than conventional sign materials. King ColorCore is a superior homogeneous sheet, made with a unique state-of-the-art continuous process called PolyFusion®. It is manufactured to the highest standards in the industry. King ColorCore® is upgradable with our exclusive antimicrobial additive King MicroShield®. The latest technology for protecting the product surface against a broad spectrum of damaging bacteria, algae, and fungi by reducing the amount of microbes by 99.99% and killing the microbes on contact.
