EPDM sponge comes in many forms and has been adapted over the years to fit a variety of different purposes. Each EPDM variation has different chemical properties which produce alternate results. Properties such as temperature range, water absorption, flame resistance and environmental protection can be tested to ensure that the EPDM material is utilised in its appropriate form.
