Dount Foam Fender Specifications Summary
Dimensions
Outer Diameter: Ranges widely, from around 200 mm for small boat applications to
over 2000 mm for large commercial vessels or industrial marine
setups. The size is chosen based on the vessel's size and expected
impact forces.
Inner Diameter: Varies between 50 mm and 1000 mm. Smaller inner diameters are for
tight - mounting around specific parts, while larger ones offer
more flexibility in installation or can accommodate larger objects
passing through.
Height (Thickness): Usually falls in the range of 50 mm to 500 mm. Dount foam fenders are better at handling high - energy impacts.
Material - related Specifications
Core Material: Primarily made of high - density closed - cell foam. This type of
foam provides good buoyancy, resists water absorption, and has
excellent shock - absorbing properties.
Outer Layer: May be covered with a tough, abrasion - resistant layer such as
synthetic rubber or a specialized fabric. This layer protects the
foam core from damage due to sunlight, abrasion, and general wear
and tear in the marine environment.
Performance - related Specifications
Energy Absorption: Capable of absorbing and dissipating kinetic energy during impact.
The amount of energy absorbed depends on factors like foam density,
thickness, and fender size.
Buoyancy: Exhibits natural buoyancy, which helps keep it in position in the
water and reduces the effective weight when installed on a vessel,
contributing to vessel stability.
Durability: Can withstand repeated impacts, abrasion, and exposure to harsh
marine conditions including saltwater, sunlight, and temperature
variations.
