Navigational Aids, Buoys, Fenders, Floats Bouyant
We are representatives and distributors of buoys Utibuoys
manufactured by Urethane Technologies, Inc. wich include marine
lanterns, RACON's and other components from different manufacturers.
Teh buoys are manufactured with a closed cell,
cross linked polyethylene foam sheets that are heat laminated (i.e. no glue)
together and then machined to the proper shape.
The foam is then coated with a thick, very tough,
elastomeric Seathane polyurethane protective skin that is reinforced with
Spectra (a 375,000 p.s.i. tensile strength) woven fibers.
We use a 4 lb. / cu. ft. density foam below the water
line and a 2 lb. / cu. ft. density foam above the water line of the buoy.
The buoys will withstand severe collisions.
The floatation foam is protected by our Seathane®
polyurethane skin. This skin has a 500% elongation and a 4500 lb./ sq.
inch tensile strength. On our larger buoys and on buoys that will receive
rough abuse the skin is reinforced with Spectra® fiber which has
a 375,000 lb./ sq. inch tensile strength. Polyurethane protective shin also
has better color retention than rotationally molded polyethylene shells do.
