Rubber specification

By far the most important factor affecting fender performance is rubber type and rubber compound composition. However, the behavior of rubber under stress is unique, so it is essential that precisely the right formulation is specified and critically, finds its way to the final product to ensure a long and robust service life. In marine fenders, three key factors – velocity factor, temperature factor and longevity – are affected by rubber grade and compound formulation.

The properties of fenders vary dramatically depending on their composition; rubber compound composition should be built into specifications in order to guarantee performance and lifecycle.

The model specification (below) is intended to guide specifies in ensuring the correct rubber compound composition and physical properties required to optimize performance and guarantee longevity.
