- Eco Friendly Certified Buoys
Core Technology for Eco-friendly Marine Equipment
The heart of core technology for eco-friendly marine equipment needs to be using composite technology in
consideration of environmental friendliness, recyclability, functionality, and economy to select environmentally friendly materials, recyclable materials, and materials that can provide excellent functionality in a harsh marine
environment.
Polyfoam Co., Ltd. is developing superior products on the basis of our accumulated technical abilities and provides only certified products in the interest of improving the marine environment.
Business Areas
Eco Friendly Certified Buoys
Certified buoys that meet governmental eco friendly buoy supply policies and the needs of fishermen at aquafarms
(constructed with core layer air inflation + EPP layer + exterior skin for excellent buoyancy and superior durability)
Floating Marine Structures
We use polyethylene to make marine equipment that uses environmentally-friendly materials, like high-strength
square supports made from AL materials, polyethylene footholds, and anti-slip edge mats.
They not only have
excellent seaworthiness, durability, and safety, but are also easy to install and maintain.
Certified Buoy Production Technology
Buoy
Buoys are floating objects that are left on the surface of the water as markers for sea routes or the location of
fishing equipment.
They are used for the cultivation of kelp and hanging shellfish (oysters and mussels), ascidians (sea squirt and
warty sea squirt), and for inclosing net cultivation.
They are used as floats for fisheries and marine facilities like landing floats, barges, floating dome houses, and rafts.
Certified Buoys
Certified buoys are buoys which have met the Ministry of Maritime Affairs and Fisheries’ certified buoy standards for quality and performance and are registered with a certifying institution for use as a replacement for exploded polystyrene buoys for use in aquafarming institutions, fisheries, and with fishing craft and fishing equipment.

AFB Certified Buoy Characteristics
Friendly
buoy performance standards: Ministry of Maritime
Affairs and Fisheries Certified Buoy Registration
· Does not produce microplastics, and eliminates root cause of
environmental pollution with semi-permanent installation
an
Durability
construction including EPP layer and outer skin maintains
superior buoyancy
· The EPP foam acts as a bufef r layer protecting the inner skin,
absorbing shocks from the outer skin and increasing durability
· Can be used semi-permanently to reduce use of other materials and repeated use, and frequency of recycling
· The EPP layer does not produce soot during incineration and is a convenient material for recycling
and
functional
· The EPP layer offers superior elasticity, making it an exceptionally effective shock absorber for its weight
· Has exceptional strength, flexibility, and elasticity, allowing it to protect the surface even with changes to the marine environment
AFB Certified Buoy
Three-layer construction with PE outer and inner skin with EPE/EPP, etc., making it a flotation device with excellent buoyancy and durability

Types of Marine Equipment
Landing Decks
A square structure which floats on top of the water and is used for ship mooring for boat mooring facilities, fishery management vessels, fishery guidance boats, and boat work facilities, etc.
Barges
These are broad, flat floating structures made to be used on lakes and in marine environments, and are used for management facilities, fishery work, storage of discarded fishing equipment, trash collection, etc.
Fish Cages
These are facilities used for fish cultivation in which a fence is built in the water and a net is hung across it. They are used for inclosed net aquafarms, abalone aquafarms, scallop aquafarms, spawning grounds, etc.
