Foam filled fenders are the new type floating fenders which have most advantages of maintance free and heavy duty. Comparing with pneumatic fenders, foam fenders is advanced for the "soft bounce" and free maintance. So foam fenders are rapidly become the best bumpers for platform and docks.People can easy find foam filled fenders are mostly equipped for most salvage tugs and oil platforms. Such usages are most heavy and in fierce environments.
There is no ISO standard of foam filled fenders now so we design the test methods according to USACE / NAVFAC / AFCESA demand.

Test methods
1. Fender Cyclic-Compression Test
Compress the fender along its diameter between two parallel flat plate surfaces to a compressed dimension of 40 percent of its original diameter. Repeat the compression and release cyclic loadings for a minimum of 10 full cycles of compression. Permanent deformation, cracking, or tearing of the fender skin, fender core, or end fittings shall constitute failure of this test.
2. Fender Sustained-Load Test
Apply a 667 KN compressive load and hold this load for 24 hours. Record load and deflection each hour. Immediately after release of the load, measure rebound of the fender. Continue to record fender rebound for 24 hours. Failure of the fender or foam core to rebound to 90 percent of its original diameter after 24 hours shall constitute failure of this test. If the foam core is not bonded to the skin of the fender, devise and execute a means for measuring rebound of the foam core and for measuring the void between the foam core and the skin. The maximum rate of compression per minute shall be 20 percent of the total reaction force at 60 percent compression. The full compression cycle, not including rebound, shall take a minimum of 5 minutes.
3. Fender Pull-Through Test
Devise and perform a test which will measure the resistance of the end fittings and internal chain to pull through the longitudinal axis of the fender. Failure of the chain, end fittings, or skin to resist at least 178 KN of pull-through tension shall constitute failure of this test. After loading, evidence of permanent deformation, cracking, or tearing of the fender or end fittings shall also constitute failure of this test.
4. Skin Thickness Core Test
Material control
Foam Core
The energy absorbing foam core shall be a closed-cell cross-linked
polyethylene foam with the following properties:
a. Density, ASTM D 1667,
b. Tensile strength, ASTM D 3575 or ASTM D 412,
c. Elongation (ultimate), ASTM D 3575 or ASTM D 412,
d. Water absorption percent volume after 24 hour exposure, ASTM D 1667
e. Continuous service temperature,
f. 25 percent compressive set, ASTM D 1667,
g. 50 percent compressive set, ASTM D 3575,
Elastomer
The elastomer used in the fender skin shall be 100 percent PTMEG (polytetramethyleneether glycol) polyether urethane elastomer, ultraviolet stabilized with 2.5 percent carbon black or equivalent, with the following unreinforced properties:
a. Shore A. hardness, ASTM D 2240, 80 to 95.
b. Tensile strength, ASTM D 412, 19.3 MPa
