The outer skin of foam fenders is usually made of polyurethane (PU) or polyurea elastomer, reinforced with nylon tire cord fabric. This skin is thick, wear-resistant, and non-marking. The fabric inside increases the tear and tensile strength.
Why This Topic Matters Now
At Sunhelm, we’ve seen many marine fender and ship fender users face high repair costs because of damaged fender skins. Imagine a heavy ship docking and hitting a weak fender. If the skin is too soft or thin, it can tear or even scratch the ship and dock. This can lead to accidents or delays.
As more ports operate around the clock, the demand for foam fenders for sale is growing. That’s why it’s important to know what fender skins are made of. Good skin materials make the fender last longer and keep ships safe.
Main Structure of a Foam Filled Fender
1. Closed-cell Cross-linked Foam Core
The foam inside is strong, keeps its shape even when damaged, and always floats.
2. Reinforced Polyurethane or Polyurea Skin
This outer skin stands up to seawater, sun, high and low temperatures, and oil. Nylon fabric inside the skin is placed in spiral layers to add strength and stop tears.
3. Chain and End Fittings Inside
Heavy-duty chains and metal parts are built into the fender to handle impact. These parts help spread the force and protect the skin from being cut or pulled.
Other questions

We’ll explain how they work in rough seas, fast docking, and frequent port use.
2. Want to lower maintenance costs and increase lifespan?
Foam filled fenders don’t leak air. Even if the skin is cut, they keep working. They need very little maintenance and last for years.
3. Curious about how materials affect energy absorption?
You’ll see why foam fenders can absorb high impact and give low reaction force. This protects the ship and the dock from damage.

FAQ
Q1: What other materials are used for marine fender skins?
Besides PU or polyurea, some use synthetic rubber or plastic, but these don’t last as long.
Q2: Why choose foam filled fenders?
They never deflate, are easy to use, strong, and absorb energy well.
Q3: What’s the difference between polyurethane and polyurea skin?
Polyurea is harder and resists chemicals better. PU is more flexible and easier to shape. Sunhelm can offer both.
Q4: How do you install foam fenders?
You can hang them with ropes or chains. Use 2-point or 4-point mounting depending on your ship and dock setup.
Q5: How do you make the fender skin last longer?
Wash it often, avoid salt buildup, and don’t let sharp objects touch it. You can also upgrade to tire nets for extra strength.
