Rigid polyurethane (PU) delivers a broad range of chemical resistance along with superior impact strength.
Description
Rigid polyurethane (PU) delivers a broad range of chemical resistance along with superior impact strength. Polyurethane combines the structural and impact characteristics of amorphous materials like polycarbonate, yet offers the excellent chemical resistance of semi-crystalline materials. Polymershapes offers polyurethane sheet, rod and tube in a variety of colors and sizes.
Polyurethane provides excellent light transmission, good temperature resistance, and is easily machined while retaining superior dimensional stability. When the translucent grade is polished, it provides excellent clarity. Polyurethane is a good candidate for metal, glass, or ceramic replacement, and can also be used in applications where polycarbonate, nylon or acetal are being considered.
Polyurethane sheet is commonly used as a liner in a variety of handling or conveying applications for bulk materials including grain, sand and gravel, crushed stone, coal, metals, salt and more. It offers excellent abrasion resistance, noise and vibration abatement, product cushioning, and insulation. It is often an ideal replacement for OEM equipment originally shipped with rubber or other material that breaks down with wear.
Polymershapes can meet all your needs for rigid polyurethane sheet, rod and tube. We can cut to the size you specify, so you receive the right the amount of material for your projects.
