A rigid foam blank is molded shaped to specification then covered with fiberglass cloth and polyester resin. Some boat hulls have a rigid polyurethane foam core sandwiched between fiberglass skins. The foam provides strength buoyancy and sound deadening. Boat decks and outdoor marine surface areas edit. Some boat decks including U.S Navy vessels use specialized polyurethane sealants to protect from constant moisture and harsh oceanic elements. As an example Durabak-M26 uses a custom single-part polyurethane to prevent water seepage to unwanted areas. Polyurethane has been used to make several Tennis Overgrips such as Yonex Super Grap Wilson Pro Overgrip and many other grips.

clarification needed Polyurethane foams are now used in high-temperature oil filter applications. Polyurethane foam including foam rubber is sometimes made using small amounts of blowing agents to give less dense foam better cushioning/energy absorption or thermal insulation. In the early 1990s because of their impact on ozone depletion the Montreal Protocol restricted the use of many chlorine containing blowing agents such as trichlorofluoromethane CFC-11. By the late 1990s blowing agents such as carbon dioxide pentane 1112-tetrafluoroethane HFC-134a and 11133-pentafluoropropane HFC-245fa were widely used in North America and the EU although chlorinated blowing agents remained in use in many developing countries.

This property is prompted by the high costs incurred in the transportation of bulk products with a relatively light weight over long distances. Production of polyurethane foam. Three basic raw materials play a key role in the production of polyurethane foam polyol isocyanate and water. Agents such as catalysts and stabilisers are used to support the chemical process. In addition further additives can be added to the formula with a view to obtaining specific product properties such as colour fire-retardant or anti-static effect etc. The petrochemical industry refines 95% of the crude oil it processes into fuels naphtha and allied products.

Polyurethane Applications.
Polyurethane epoxy resins seal boat hulls from water weather corrosion and elements that increase drag affect hydrodynamics and reduce durability. Boaters today can have the comforts of home on the water thanks in part to flexible polyurethane foam. In addition rigid polyurethane foam insulates boats from noise and temperature extremes provides abrasion and tear resistance and increases load-bearing capacity all while adding minimal weight. Thermoplastic polyurethane is also great for use in the maritime industry. It is elastic durable and an easily processed substance well suited for wire and cable coatings engine tubing drive belts hydraulic hoses and seals and even ship molding. Medical Polyurethanes are commonly used in a number of medical applications including catheter and general purpose tubing hospital bedding surgical drapes wound dressings and a variety of injection-molded devices.
