What is high density urethane foam?
High density urethane foam board also known as HDU board is used for hand-carved signs as well as CNC-machining. Precision Board Plus™ High Density Urethane (PBLT) is a “closed cell” rigid polyurethane product made specifically for applications of up to 200° F continuous exposure.
What is a urethane board?
Product Details. Precision Board Plus High Density Urethane (also known as tooling board, a competitor to RenShape or Ren board) is a closed cell rigid urethane foam board that can withstand up to 200º F continuous exposure. It can be cut or bonded into a variety of shapes for final machining or shaping.
What material is HDU?
High-Density-Urethane
High-Density-Urethane (HDU) is a rigid, “closed-cell” material. It is impervious to all petroleum-based solvents. Engineered specifically to make signs, HDU is waterproof and will not shrink or swell. As a result, it is easier to cut, route and manufacture, reducing the overall cost.
Is high density urethane waterproof?
High Density Urethane foam is a waterproof sign material made for creating dimensional signs at a lower cost (and weight!) than using wood. This strong material creates a carved look and can feature multiple backgrounds in different thicknesses for outdoor signage.
What are HDU signs?
HDU signs are signs made out of high-density urethane. Many signs are made of this material due to its durability and versatile use in various sign constructions. HDU signs work wonderfully for anything from dimensional letters and signs to monument signs.
How strong is HDU?
HDU can withstand temperatures ranging from -30 degrees to 200 degrees Fahrenheit. HDU does not decompose, rot, or crack like wood does.
Is HDU the same as ICU?
The main difference between intensive care and high dependency care is the nurse to patient ratio. Usually an ICU patient requires one to one nursing care, whilst a high dependancy patient requires one nurse to every two patients.
What is high density polyurethane?
Precision Board Plus™ High Density Urethane (PBLT) is a “closed cell” rigid polyurethane product made specifically for applications of up to 200°F continuous exposure. High Density Urethane is available in a wide range of sheet sizes, thicknesses, and densities.
What happens if polyurethane foam gets wet?
If polyurethane foam gets wet, the cells will soak up the water. The biocide treatment is important because it prevents mold and mildew growth that can occur when wet foam dries out.
