PUR (polyurethane) product family features

Polyurethanes are extremely flexible, elastic plastics, which are close to elastomers (rubber, silicone products) in their flexibility. In addition, they are highly resistant to abrasion and chemicals. A wide range of hardnesses, colours and densities are available. The Shore A scale is commonly used to determine hardness, with Sh A between 60 and 95 typically available. They are also available in rod, tube and plate formats.

Some important features

Elongation at break: 250-700%
Application temperature: up to approx. 80°C
Excellent wear resistance, e.g. when abraded by small particles

Main areas of application

Silents, leaf springs, buffers, rollers, contact surfaces/coatings. The harder PUR semi-finished products (such as Ebaboard) are sought-after materials for models, patterns and moulds due to their excellent machinability, dimensional stability and aesthetic appearance.

Machining technology

Chipping (turning, milling, drilling, sawing): traditional metalworking tools, in some cases woodworking tools - carbon steel, high speed steel, carbide, diamond - can be used with a sharp finish, but especially for softer polyurethanes it is recommended to cool the workpiece before machining.

Gluing: feasible.

Available formats
