CORAFOAM HDU is a high-density polyurethane sheet that is versatile and resistant to weather, solvents, and moisture. It’s commonly used in sign making, modeling, and aerospace industries. With a consistent texture and a wide range of densities, it’s easy to finish, carve, or machine. The most popular densities for sign making are 15lb and 20lb. 15lb is recommended for indoor and outdoor signage, while 20lb is a great alternative for projects where strength or weather is a major concern, or as a potential option to reduce priming/finishing time.
