Aging Resistance Pneumatic Rubber Fender ISO 17357-1:2014 Certified with High Energy Absorption for Marine Protection

As global demand for heavy industrial safety and operational efficiency continues to rise, our custom marine rigging provides high-strength, certified industrial lifting solutions. Since 1994, we have remained committed to providing the most reliable hardware support for the offshore, shipping, and construction industries.

From high-tensile wire rope slings to precision rigging hardware, the Marine Rigging expert team combines advanced horizontal proof-testing technology with strict OSHA compliance standards. Each component is meticulously selected and professionally fabricated to ensure maximum safety in the harshest maritime conditions and operational environments.

• Unmatched Safety: All products are load-tested to ensure a 5:1 Safety Factor (SF).
• Rapid Customization: In-house fabrication shop supports fast wire rope swaging and synthetic sling sewing for urgent delivery.
• Expert Technical Support: Over 30 years of experience with rigging specialists providing on-site installation guidance.
• Corrosion Resistance: Optimized for saltwater environments with Hot-Dip Galvanized and Stainless Steel material options.

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%.

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.
