Avoid Pitfalls-How to Choose Foam Fender and Supplier
Foam Fender Market Status
Foam fenders have a wide range of applications and a broad product market, so there are a large number of product manufacturers, but the quality on the market is uneven. In order to reduce costs, the products lose their basic performance of energy absorption and reaction force, and a large number of accidents caused damage to berthed vessels or impacts on piers. At the same time, due to the high value of the foam fender itself, users suffered huge economic losses.
For Example:
- Foam fender produced according to lower tolerances to reduce costs.
- Misleading customers on the basis of foam core density, combined with price (Learn More).
- Windingstructure foam core: low cost, poor performance of energy absorption and reaction force (Used by most manufacturers).
- The foam core is made of mixed density material, which has low cost and low performance.
- The foam core is directly filled with waste materials, which loses the basic performance of foam fender.
- Using poor qualitycentral axis, low cost, low strength, easy to break.
- Central axis is filled with scrap steel sand/cement to meet the weight requirements of customer.
The above situations exist alone or at the same time. Customers must understand clearly before making a decision when purchasing, otherwise it will bring you a large economic loss.
The hazards of low-quality foam fenders
Low-quality foam fenders may be an advantage in terms of purchase cost, but in practical applications, foam fenders essentially test its energy absorption and reaction performance, safety and long-term stability. If the long-term application cost is considered, low-quality foam fenders have no any advantage, which will directly lead to economic losses for customers and threaten the safety of personnel/ships/docks.
- Inferior foam fender have the problem of foam core collapsed, because foam core material is not properly selected (waste/mixturematerial), cannot withstand high-intensity repeated impacts, and foam fender will have non-elastic deformation, resulting in performance degradation, or even loss of performance and service life greatly reduced,damage to ships and docks.
- Inferior foam fender have the problem of Polyurethanecoating Due to the insufficient thickness and quality of Polyurethane reinforcement layer on the surface of foam fender, and the unreasonable layout of tire cord layers, the force on the surface is relatively concentrated and will be cracked. After long-term application, the foam core absorbs moisture and performance declines,the cracking gap will become larger and larger, affecting fender service life.
- Inferior foam fenderhave the problem of central axis damaged. The central axis with low strength will be bent,deformed or even broken during repeated compression. The foam fender loses its supporting function. If the inspection is not timely, it will bring direct economic losses.
How should customers choose foam fenders
The three most important parts of foam fender are: Foam Core, polyurethane Coating, and Central Axis. Customers must pay attention to the quality problems of these three parts when choosing, so as to avoid unnecessary losses.
Foam Core: The foam core is the key factor to reflect the foam fender performance.The closed-cell foam core should be selected. At the same time, according to different expansion ratios, the foam density will be different. It is necessary to communicate with the manufacturer according to the actual application.
Polyurethane Coating: It is the protective layer of foam fender, which has the effect of dispersing the force. The quality and thickness of polyurethane coating can resist the damage to foam fender caused by friction. At the same time, attention should be paid to the structural layout of tire cord layer.
Central Axis: The central axis is the key point to support the foam fender. The material and strength of the central axis determine the service life of foam fender. Central axis’s reasonable size and strength can greatly improve the overall cost performance of the product.
