Marine Rubber Fenders pneumatic CTN type with sling made of natural rubber providing strong tensile and wear resistant performance

Product Description:

Material Advantages:
High-Quality Pneumatic CTN Type Marine Rubber Fender with Sling | ISO 17357:2014 Certified, Heavy-Duty Anti-Collision Solution for Ships, Ports & Offshore Operations
As a professional marine safety equipment manufacturer, we proudly present our Pneumatic CTN Type Marine Rubber Fenders with Sling — the perfect combination of CTN’s rugged protection and sling’s flexible installation, designed to safeguard vessels, ports, and offshore structures from collision damage during berthing, ship-to-ship (STS) transfers, and mooring operations. Compliant with international standards and crafted with premium materials, this fender is a reliable choice for marine operators worldwide.

Manufacturing Process:
 
Material Pretreatment: Synthetic rubber raw materials are mixed with reinforcing agents, antioxidants, and other additives in precise proportions, and then plasticized at 120-150℃ using an internal mixer to ensure uniform rubber texture and stable elasticity.
Skeleton and Airbag Molding: High-strength polyester cord fabric is used as the skeleton layer, wound into a 600*1000mm cylindrical structure, with an inner rubber airtight layer. Preliminary shaping is achieved using a vulcanizing machine to ensure airtightness.
Overall Vulcanization Process: The molded fender is placed in a large vulcanizing tank and vulcanized at 150-160℃ and 1.5-2.0MPa pressure for 4-6 hours to allow the rubber molecules to fully cross-link, improving material strength and anti-aging properties.
Accessory Assembly and Sealing: Inflation valves, flange joints, and other accessories are installed. Secondary vulcanization sealing is used at the interfaces to ensure no air leakage. A wear-resistant protective coating is applied to the outer layer to enhance surface abrasion resistance.
Finished product inspection: Products pass airtightness tests (pressurized to 0.3-0.5MPa and held for 24 hours without leakage), impact resistance tests, and dimensional accuracy tests. Unqualified products are reworked directly, and the factory pass rate is over 99%.

Feature:

Pneumatic rubber fenders are a world-leading marine anti-collision solution for ship-to-ship and ship-to-dock operations. They are an ideal ship protection solution and widely used in large oil tankers, liquefied petroleum gas ships, offshore platforms, bulk carriers, floating structures, large docks, and ports.

Our fenders are manufactured using a synthetic cord reinforced rubber sheet, with compressed air inside which can float on water as a protective medium. All our pneumatic rubber fenders are manufactured to a high quality and fully compliant to ISO 17357-1:2014 standards. This ensures longevity and low maintenance, no matter how demanding the environment.
