Why Choose Diab Divinycell H80 Plain Core Sheets for Your Marine Project

by Maisie

Selecting the right materials is a crucial foundation for any marine project. One option that most people vouch for is Diab Divinycell H80 Plain Core Sheets. These sheets, made from closed-cell foam, offer a range of benefits that make them well-suited for various marine applications.

Let’s take an in-depth look at why these core sheets are an excellent choice for your marine project.

Benefits of Divinycell H-80

Divinycell H-80 is a valuable structural foam core in compound sandwich construction. The H-80 has a five-pound per cubic foot density and is helpful for kiteboards, skimboards, and wakeboards. Separation of two materials using a lightweight material in between increases the strength and stiffness of the structure at low weight and decreases the costs.

Any moving machine consumes energy; the heavier the device, the more power it consumes. Using sandwich composites makes structures lighter, which means it consumes less energy and involves less material consumption, thus creating a smaller carbon footprint.

Due to the rising fuel costs, most industries, including the marine industry, have realized it costs less to use lightweight solutions. Plain Divinycell H-80 is becoming popular for marine projects and has many properties that make them ideal. Divinycell H-80 makes the best foam core to use in a marine project for various reasons:

Excellent Strength-to-Weight Ratio

Divinycell H-80 sheets have an excellent strength-to-weight ratio. They exhibit impressive shear properties and compressive strength at elevated and ambient temperatures.

Shear properties define the H-80’s ability to bear stress before breaking or deforming. The strength-to-weight or density ratio means the strength of the H-80 sheets divided by their mass or weight. The ratio allows for higher payload capacity, longer ranges, and incredible speeds.


Divinycell H -80 is lightweight and thus suitable for boats, doors, containers, or reefers. Since they are contour-resistant, plain Divinycell H-80 makes an excellent choice for boat hulls and decks. H-80 offers excellent adhesion to a boat’s inner surfaces when used in hulls and ensures more buoyancy.

Low Water Absorption

Due to its closed-cell structure, Divinycell H-80 has low water absorption, making it perfect for marine use.


Divinycell H-80 is compatible with most manufacturing systems, adhesives, and resins such as epoxy, polyester, and vinyl ester. They are economical and have a low uptake of resin.

Good Thermal Insulation

Heat insulation is essential in boats that frequently have people on board, such as sailing, long boats, or cruise ships. H-80 sheets ensure uniform insulation, keeping the vessel’s occupants warm while out in the water. H-80’s thermal conductivity is from + 10°C or +50°F.

Chemical Resistance

H-80 is strong and has excellent chemical resistance, and it is also resistant to grease, rot, and mildew, which can grow on surfaces due to the damp environment.

Excellent Adhesion

Divinycell H-80 is excellent on the deck’s underside, the stern’s surface, or under bench seats and gunwales. The H-80 sheets have excellent adhesion that prevents movement and does not rub against the hull. The rubbing may eventually create some particles that can block pumps and valves. If the vessel floods, the buoyancy may become compromised, posing a danger to the vessel’s occupants.

The adhesive between the core and the vessel face must have the ability to transfer shear force between them. The glue must also have the ability to carry tensile and shear stress. The rule of thumb is that the adhesive must be able to take up similar shear stress as the core, which could be various materials such as aluminum, wood, or metal.

Fatigue Resistance

Fatigue is the burden of repetitive stress or continual cyclic loads on parts. Fatigue is also the principal stress in slamming on a vessel’s hull. Divinycell H-80 sheets have excellent fatigue resistance properties, making them more durable. The ductile qualities of Divinycell H-80 plain sheets make them ideal for applications subjected to fatigue, impact, or slamming loads. Other brittle materials may shatter due to impact, but due to their elasticity, H-80 sheets absorb energy without any risk of structural failure.

Easy to Handle

Divinycell H-80 plain sheets are easy to cut, shape or thermoform using heat. The sheets provide excellent temperature resistance, and you can thermoform them into shape. H-80’s thermal properties guarantee accuracy and reliability for your marine project.

Divinycell H-80 plain sheets have numerous advantages for a marine project. Their chemical resistance, low water absorption, high fatigue resistance, outstanding thermal insulation, good adhesive properties, and compatibility with most resins make them ideal for water-based projects.
