King MediGrade® is a super tough, high-density polyethylene building sheet with an advanced antimicrobial technology for protecting the product surface against stain and odor causing bacteria, algae and fungi. Unlike surface antimicrobials, King Plastic’s advanced antimicrobial technology protects against bacterial degradation for the lifetime of the product. It is the product of a proprietary process called K-Stran™, the most advanced manufacturing process for superior flatness and consistency. King MediGrade® has a matte gloss finish on both sides of the sheet. It is environmentally stabilized to withstand the harshest outdoor conditions. King MediGrade® will not rust, delaminate or rot when exposed to UV, humidity or water. Healthcare facilities, medical equipment and case goods made with King MediGrade® will stay cleaner and fresher between cleanings. Studies have shown that surfaces with the antimicrobial technology can inhibit the amount of certain product-damaging bacteria by 99.99%* compared to an untreated surface. The polymer sheet never needs painting or refinishing, works like wood and is easy to fabricate using common woodworking tools and techniques.
