1.The above performance parameters measured are based on static state;
2.Above reaction force and energy absorption to lerance of ±10%3..Fender accessories have all been hot dip galvanized anti-corrosion treatment.
2/Product information:
Polyurethane floating fender is also a kind of compressed fender which builds outer protective layer with polyurethane material and adopts polyurethane foaming material or plastic foaming as buffer medium ; the destructive effects on docks and ships will be reduced by the compression to absorb the impact energy from ships in the course of using polyurethane floating fender .
The polyurethane floating fender reaction force grows from a small beginning into a mighty and has high energy absorbing quantity which is appropriate for the open dock , gravity and has high energy absorbing quantity which is appreciate for the open dock , gravity type dock of the open seas , dock with large special tidal range and open seas two approach ship etc . it has been widely used for the places of the docks , boatyard and ship boards from place to place .
Foam Filled Fenders are versatile, robust and suitable for almost all applications. The manufacturing process allows for virtually any size of fender to be constructed and selecting the appropriate grade of foam core and elastomeric skin means the performance of a fender can be precisely gauged to meet specific specification requirements.
Characteristically Foam Filled Fenders have a high energy absorption compared to their reactive load meaning they are ideal for existing structures and certain hull types such as catamarans and cruise ships.
2/Construction Features of Foam Filled Fender:
Foam Filled Fender is a kind of constructive fender with polyurea materials as its outer protective layer and EVA foam core forming the resilient inner part.
The Foam Filled Fenders are constructed of three parts each providing an important function in the construction and lifespan of the fender.
The three parts are (1) The closed cell EVA foam.(2) Outer rubber + nylon cord fabrics. (3) Polyurea spraying coat.
1>Foam Core
The closed cell EVA foam core used inside offers un-sink ability during operation.
Outer Rubber + Nylon Cord Fabrics
The outer rubber + nylon cord fabrics is specifically designed to seal EVA foam inside and to prevent any leakage.
2>Polyurea Spraying Coating
Polyurea coating is permanent spray on coatings that protect the surface of fender body. It is more durable than rubber and flexible in all weather conditions; no softening in heat or becoming brittle in cold. Dent, scratch and chemical resistant.
3/Quality Control of Raw Materials
The EVA foam we use in the construction of our Foam Filled Fenders is the closed cell type. It is made from Ethylene Vinyl Acetate and blended copolymers. It has a high level of chemical cross linking. These foams are flexible and resilient making them ideal for fendering products. Importantly, the foams are also chemically inert and nonabsorbentmaking them suitable for use in marine environments.
Our closed cell EVA foams are available in a range of densities from 120 kg/m³ to 140 kg/m³.
4/Performance characteristics:
(1) polyurethane foam fender is with the use of high quality synthetic rubber nylon cord.
(2)Good ageing resistance performance character is tics.
(3using compressed air as damping medium, the rubber can transform flexibly under pressure, with large contact area, small reaction and absorb large amount of energy.
(4when berthing, the ship is almost at a certain angle, the polyurethane foam fender can realize contact in a certain angle by bringing full play to its performance.
(5floating on the water surface, even the ship fluctuate and sway resulting from ebb and flow and waves, the pneumatic
(6)simple installation, simply installed on the wharf and anchor mast.
(7)Ageing resistance, corrosion resistance
(8)Long service life
