Properties of Polyurethane Rod:
Polyurethane Rod is available in a large variety of hardness' ranging from 10 Shore A which is softer than a pencil rubber to around 90 Shore D which is as hard as Nylon. Polyurethane Rod is also available in many colours which means that a customer can personalise their components or use a colour coding system to identify particular components at a glance.
Polyurethane Rod is also excellent for impact resistance also and its elastic properties. This varies as the Shore hardness increases but even the hardest grades outperform other similar materials and will resist cracking and any permanent deformation much more than traditional rubber.
Polyurethane Rod will also outperform materials such as rubber when it comes to higher and lower temperature resistance, Polyurethane will generally resist temperatures of around plus 100°C where rubber seems to degenerate at around plus 70°C.
Another important property that Polyurethane Rod has is its resistance to abrasion and cutting. It is quite exceptional in this area and Polyurethane is often specified within the glass and glazing industry as rollers and also within the aggregates industry where very abrasive products such as sand and gravel are employed.
