Description
High Energy, Low Reaction
The high elasticity of expanded PE or EVA ensures high energy
absorption with low reaction force, which is essential to eliminate
the risk of damage to the vessel hull.
To guarantee a good adhesion of the polyurethane cover to the
expanded polyethylene or EVA, Donghai studied a special type of
expanded material with a polyethylene compound that presents a very
good adhesion characteristic with elastomer polyurethanes.
The expanded PE is wrapped and welded around the steel core,
and is covered by an high thickness of elastomer polyurethane that
gives goods abrasion and breaking resistance, which ensure a long
performance even under strenuous conditions.
Unsinkable
Donghai foam fenders are entirely made of closed cell
elastic expanded PE or EVA that guarantees unsinkability even in
case of damage caused by breaking, rupturing or shearing when
hitting rough vessel sides. Ever cell is separate and so water
cannot migrate into the foam.
Strong Reinforcement
In order enhance the performance of foam fenders, nylon fabric
layers are individually applied at the optimum position. And skin
and reinforcement are applied simultaneously. Meanwhile, multiple
homogeneous layers increasing strength and additional reinforcement
are applied as the transition layer. Special layers are applied to
both ends where stresses are highest. This system enhances the
ability of resisting to deflection and shearing force.
Wear
Resistant
The polyurethane or SUPA elastomer is spray applied. This
creates a high quality and homogeneous skin matrix combining
extreme wear resistance with non-marking properties and the option
of high visibility colors.
