Polyesters are ideally suited to abrasion and high load bearing applications. They generally exhibit a good balance of physical properties and due to the composition of the material are often more economical options than the other two main polyurethane grades, Polyethers and Polycaprolactones. They provide excellent damping solutions such as shock and vibration absorbers.
The chemical structure of Polyesters contain a double oxygen bond with a carbon atom. This makes the polymer more resistant to oils and chemicals than other material options. However, this bond is susceptible to hydrolysis and so is not recommended for water-based applications or environments with high humidity.
· High temperature stability
· Excellent abrasion resistance (in comparison to Polyethers)
· Excellent chemical & oil resistance (in comparison to Polyethers)
