EPDM/PVC Cylindrical D Shape Dock Bumper Rubber Fender with Cutting Service for Marine and Boat

Product Description:

Material Advantages:

### Core Material Advantages

1. **EPDM Rubber's Weather and Corrosion Resistance:** Excellent resistance to UV rays and extreme temperatures (-40℃~120℃), making it resistant to aging and cracking even after long-term exposure to marine environments. Resistant to seawater, salt spray, and grease, resulting in a long service life.

2. **Balance Between PVC's Structural Stability and Cost:** Enhances product rigidity and shape retention, preventing deformation under long-term pressure. When combined with EPDM, it controls costs while maintaining performance, offering better value.

3. **Comprehensive Mechanical Properties of the Composite Material:** Excellent elastic recovery effectively absorbs the impact of ship berthing, reducing damage to the hull and dock. High wear resistance and tear strength, capable of withstanding frequent collisions and friction.

### Scene Adaptability Advantages

- In marine scenarios, it can withstand the strong corrosion of the marine atmosphere and extreme weather, eliminating the need for frequent replacements.

- Adaptable to the berthing needs of boats of different tonnages; the D-shaped + cylindrical design combined with material elasticity provides a more balanced cushioning effect.

- Supports cutting services, can be precisely adapted to the size of docks or ships, and is easy to install with a high degree of fit.

Manufacturing Process:

### 1. Raw Material Preparation and Formulation

- Select EPDM rubber and PVC resin in the specified proportions, along with vulcanizing agents, reinforcing agents, anti-aging agents, and other additives.

- Mix thoroughly and then plasticize at high temperature using a mixer to form a uniform composite rubber substrate, ensuring core properties such as weather resistance and elasticity.

### 2. Molding and Processing (Core Process)

- Employ **extrusion molding technology** to feed the plasticized substrate into a customized D-type + cylindrical mold.

- Curing at high temperature (150℃~180℃) allows EPDM and PVC to fully fuse, forming a one-piece molded anti-collision strip blank, ensuring structural density and elasticity.

### 3. Precision Cutting and Post-Processing

- According to customer requirements, use CNC cutting equipment for fixed-length cutting, with a cutting accuracy of ±1mm.

- Grind and trim the cut surfaces to remove burrs, ensuring a good fit upon installation; some products can be drilled and grooved as needed for convenient on-site fixing.

### 4. Quality Inspection and Packaging

- Inspection items include dimensional tolerances, hardness (Shore A 55~70 degrees), tensile strength, and elastic recovery rate.

- Sampling is conducted for weather resistance and seawater corrosion resistance tests. After passing these tests, moisture-proof and scratch-proof packaging is used for easy transportation and storage.

Features:

### 1. Outstanding Protective Performance

- The composite material boasts excellent elasticity, effectively absorbing the impact of ship berthing and providing bidirectional protection for both the hull and dock structure.

- The D-shaped + cylindrical combination structure offers a large contact area and even stress distribution, preventing damage caused by concentrated localized pressure.

### 2. Durability Suitable for Harsh Environments

- Strong weather and corrosion resistance, capable of withstanding long-term exposure to marine salt spray, UV radiation, and extreme temperatures without aging or cracking.

- High abrasion and tear resistance, able to withstand frequent impacts and friction, with a service life far exceeding that of ordinary rubber products.

### 3. Flexible Installation and Adaptation

- Supports customized cutting services, precisely matching the size requirements of different docks and ships without additional cutting.

- The product is lightweight and structurally stable, requiring no complex tools for installation, ensuring a high degree of fit and secure fixation.

### 4. Significant Cost-Effectiveness

- The EPDM and PVC composite formula controls costs while maintaining high-end performance, making it more price-competitive than pure EPDM products.

- Low maintenance costs, no need for frequent replacements, and higher cost-effectiveness in the long run.

Technical Parameters:

Applications:

### 1. Dock/Port Scenarios

- Civil and Commercial Docks: Including cargo docks, passenger terminals, fishing ports, etc., used for collision protection of dock walls and berth edges.

- Container Terminals/Heavy Ports: Resist the strong impact of large cargo ships and container ships berthing, protecting the concrete or steel structure of the dock.

- Small Yacht Marinas/Sailing Ports: Lightweight protection suitable for small and medium-sized vessels, preventing scratches on the hull paint.

### 2. Ship Self-Protection Scenarios

- Ship Side Protection: Installed on the hull's berthing contact surface to reduce damage from collisions with docks and other vessels.

- Docks/Shipyards: Used for temporary protection at dock edges or during ship repairs, preventing collisions between the hull and facilities during construction.

### 3. Special Maritime Facility Scenarios

- Floating Docks/Floating Platforms: Adapted to the dynamic berthing requirements of floating structures, utilizing material elasticity to absorb the impact of swaying.

- Water walkways/viewing platforms: Used for edge protection to prevent collision damage from small sightseeing boats and speedboats when they dock.

- Industrial water facilities: Such as petrochemical wharves and hydroelectric power station reservoir wharves, resistant to corrosion and impact under special environments.
