O que é Rubber Fender?

Water vehicles like boats and ships face extreme thrust and propulsion during docking. These vehicles may get scratched or severely damaged if we don’t take the necessary steps. Therefore, we find solutions to mitigate this problem. A Rubber Fender absorbs this thrust and propulsion and protects the vehicle during docking.

A rubber fender is a cushioning equipment made from elastomeric materials. They are usually designed to absorb and dissipate kinetic energy. Docks and water vehicles both require high-quality rubber fenders to absorb this energy. Otherwise, the consequences may be severe. Essentially, a rubber fender acts as the silent guardian of maritime operations.

Therefore, we must recognize the significance of rubber fenders. Most ports, harbors, and offshore facilities ensure this as their first line of defense. This defense system primarily absorbs collisions and impacts. As a result, they can protect the vessels and structures involved and ensure the crew’s safety. In addition, a rubber fender contributes to cost savings by reducing maintenance.

Today’s article aims to highlight the fundamentals of a rubber fender. The following sections especially delve into the types, functions, applications, and benefits. In addition, we will learn some tips for maintaining the rubber fender for more extended durability.

What is Rubber Fender?

A rubber fender is a specialized protective equipment made from elastomeric materials. The manufacturing process involves five primary steps:

  1. The process begins with the material selections.
  2. The chosen rubber material is mixed with various additives.
  3. The mold or dies shape the rubber compounds into the desired fender profile.
  4. The vulcanization process crosslinks the rubber molecules to make them more efficient.
  5. The manufactured rubber fenders undergo various quality control checks.

The manufactured rubber fender then provides a wide range of physical properties. These properties may vary based on different applications.

Elasticidade

Rubber fenders are highly elastic. In this case, they allow them to deform and absorb impact energy during collisions. Then, it returns to its original shape.

Resistência à tração

A rubber fender usually provides excellent tensile strength. It means that they can withstand large stretching forces without breaking.

Resistance

A rubber fender is also resistant to various environmental factors. For example, abrasion, weather, chemicals, and temperature are noteworthy.

Compression Set Resistance

A rubber fender has good resistance to compression set. It can maintain its shape and performance even after prolonged squeezes. It also ensures the durability of the product.

How Does A Rubber Fender Work?

A rubber fender works on the principle of elasticity and molecular deformation. The process absorbs and dissipates kinetic energy during collision or contact with structures.

We know that Fender rubber seals are synthetic rubber compounds. It is composed of long polymer chains. These polymer chains are highly flexible and famous for elasticity. When a collision occurs, it exerts a certain amount of pressure on the rubber surface. The polymer chains then start to stretch and deform. Note that when a force is applied through polymer chains, it causes them to align in the direction of the applied force. As the chains stretch, they absorb and store the energy from the collision as potential energy.

Once the external force is removed, the polymer chains naturally return to their relaxed state. At this moment, they release the stored potential energy gradually. This absorbed energy is converted into heat and released through different mediums. This releasing energy mechanism acts as a cushioning method. It reduces the impact force transmitted to the vessel or structure.

Rubber fenders utilize this technique to absorb and gradually release the energy from collisions. This elasticity and molecular level deformation prevents damage to vessels and structures.
