![]() This enclosure provides the thermal insulation required by the products carried by boat.Īt Synthesia Technology we manufacture rigid closed-cell polyurethane foam systems that provide the characteristics of buoyancy and insulation required by a boat. These chambers are located in the lower part of the boat, in direct contact with the "tailor-made sandwich panel" that the closed-cell polyurethane and the hull have created. This function is useful in boats, particularly in the case of boats that have cool stores or freezers. Polyurethane foam is used in sec tors such as the building sector with the main aim of providing thermal insulation. Would you like to know about all the characteristics of our polyurethane system for boats? You will be able to check its technical sheet at the end of this article. In case of wear, leakage or breakage of the hull, closed-cell foam absorbs less water than open-cell foam. This allows the hull to be more resistant to impacts. Closed-cell polyurethane foam presents high stiffness values. Why is closed-cell foam interesting for boats? There are two types of polyurethane foam: closed-cell and open-cell. The result obtained is a tailor-made sandwich panel that confers rigidity to the hull of the ship in the presence of waves.Ĭlosed-cell polyurethane foam for boat hull Thanks to this characteristic as well as to its structure, it welds the contour between the hull and the deck. The closed-cell polyurethane expanded in situ presents a high degree of adhesion to the inner surfaces of the hull. Polyurethane is presented as a material that plays the role of these "inflated balloons": its weight is lighter than water and polyurethane foam is expanded in situ to suit the thickness of the hull of the boat. Due to the configuration of the ships, it is complicated and exaggerated to think of balloons inflated with air in the hull. The feature of buoyancy is obtained by the effect that occurs between water and the hull of the boat. This feature is achieved using elements that are lighter than water, such as air contained in an inflated balloon. From recreational boats to large transatlantic freighters, all of them must successfully go through rigorous buoyancy tests. The latter is a basic requirement to meet the highest quality standards.Ī boat must be unsinkable. ![]() In the case of boats, filling the hull with polyurethane ensures insulation and buoyancy. These Y-20 foam sheets for sale are also ideal for use as padding in bags. Because of its high density, it makes a good insulator. Like thermal tanks, boats also benefit from the advantages of using polyurethane as a large cavity filler. It does not absorb water and can be used as padding.
