Rigid Polyurethane

Rigid Polyurethane is very stiff and strong with material properties that outperform ABS plastic and rivals Nylon. This material is perfect for mechanical parts that need to be tough, heat-resistant, and abrasion-resistant.

About Rigid Polyurethane

Material details

Rigid Polyurethane (RPU) is a stiff and versatile resin based on polyurethane. It exhibits excellent performance under stress, combining strength, stiffness, and toughness. RPU is particularly well-suited for applications in consumer electronics, automotive, and industrial components where exceptional mechanical properties are required.

Technical Properties

Here are the technical properties of Rigid Polyurethane (RPU) presented in a tabular form:

Tensile strength42 - 47 MPa
Tensile modulus1700 - 2200 MPa
Tensile elongation90 - 120%
Flexural strength55 - 71 MPa
Flexural modulus1500 - 2200 MPa
HDT (0.45 MPa)70°C
HDT (1.8 MPa)55°C

Please note that these values represent the typical range for each property and may vary depending on the specific manufacturer, processing conditions, and testing methods employed. RPU's combination of stiffness, strength, and toughness makes it a highly versatile material for various applications in industries such as consumer electronics, automotive, and industrial components, where excellent mechanical properties are crucial.
