High Density Urethane (HDU) is a lightweight, high density polyurethane board that is considered to be one of the most remarkable and versatile sign substrates available in the industry. This high density foam is chemical and mold resistant and possesses strength, hardness and structural durability. HDU is fire resistant and has a high temperature rating. Additionally, it is 100% waterproof and will not decay, crack, warp or deteriorate. Coastal Enterprises Company, the HDU manufacturer, has a lifetime warranty against warping, cracking and deteriorating. HDU has exceptional machining characteristics to create dimension and texture. It can be made to emulate wood, metal, stone, rock, marble, granite, sand, dirt, brick, stucco, glass, plastic and other types of sign media. It is ideal for sandblasting, vinyl application, plant-on graphics, letters and more. It is often used in high end car prototypes, model railroads, movie sets and other faux applications. With no size constraints and unlimited finishing options, HDU means the sky is the limit - literally and figuratively.
