The development of D Type Rubber Fender has been significantly influenced by advances in materials science and manufacturing technologies. In the early years of rubber fender production, natural rubber was primarily used due to its inherent strength and elasticity. However, as the maritime industry grew and the demands for more robust and specialized fenders increased, synthetic rubber compounds were developed to enhance the properties of the fenders.

Today, D Type rubber fenders are made from a variety of synthetic rubber compounds, such as EPDM (ethylene propylene diene monomer), SBR (styrene-butadiene rubber), and NR (natural rubber), each of which offers specific advantages depending on the environment in which the fender will be used. For example, EPDM is highly resistant to UV degradation and weathering, making it ideal for outdoor marine environments. SBR offers abrasion resistance, while NR is known for its elasticity and impact resilience.

With reaction force its energy absorption is higher that of cylindrical type.
It can be installed and replaced easily.
It is widely used due to its narrow bottom width.
