For more than 30 years Divinycell H has been the first choice of leading producers of sandwich composite structures around the world. During this time the properties of Divinycell H have been continuously enhanced and improved so that it continues to be ideal for the vast majority of sandwich composite applications.
Ideal for a Wide Range of Applications
Divinycell H has been widely used over many years in virtually every application area where sandwich composites are employed. These include the marine (leisure, military and commercial), land transportation, wind energy, civil engineering/infrastructure and general industrial markets.
Material & Process Compatibility
Divinycell H is compatible with virtually all commonly used resin systems (polyester, vinyl ester and epoxy) including those with high styrene contents. Its good temperature performance with high residual strength and good dimensional stability, makes Divinycell H ideal for hand laminating, vacuum bagging, RTM (resin transfer molding) and other closed molding processes.
Mechanical Properties
In its application range Divinycell H has the highest strength to density ratio. It exhibits at both ambient and elevated temperatures impressive compressive strength and shear properties (normally the most important for a sandwich core material).

With its unique combination of features - low weight /high strength, wide processing envelope and high temperature performance - prepreg compatible Divinycell HP is ideal for a wide range of applications in the marine, wind energy, transportation and industrial markets.
Temperature Performance
With its high processing temperature, Divinycell HP can be processed at a much higher temperature than other polymer core materials in general use, making it suitable for not only low but also medium temperature prepregs.
Its elevated temperature performance is not just beneficial to prepreg users. Its high residual strength and good dimensional stability also make it ideal for vacuum bagging, infusion and RTM (resin transfer molding). HP's elevated temperature performance also extends to the 'in service' life of the component. Divinycell HP will retain a high percentage of its mechanical properties despite long term exposure to high ambient temperatures.
Strength Performance
Divinycell HP exhibits at both ambient and elevated temperatures impressive compression and shear properties (normally the most important for a sandwich core material) that are better than other commonly used ‘elevated temperature’ core materials. The figures for shear strain show that HP has good ductility and energy absorption characteristics. Testing has shown that HP also outperforms linear cores in terms of slamming resistance.
Adhesion
Divinycell HP also excels is in adhesion. Peel tests have been performed using commonly used resin systems and prepregs with superior results to other cores used for prepregs.

End Grain Balsa, a highly processed ultra light wood product, imparts impressive strength and stiffness to the sandwich panel. The end grain configuration of balsa provides high resistance to crushing, and is very difficult to tear apart. End grain balsa cored panels also have the ability to handle excessive dynamic loads with high resistance to fatigue. Until recently, end grain balsa was excluded from some weight sensitive applications, as there were lower density foam cores available. Now, through controlled growing and careful selection, BalsaLite balsa wood is competitive in weight, as well as offering superior performance in stiffness and strength, particularly where local crushing or bruising is a concern.
Nida-Core is a proud BalsaLite balsa wood supplier. BalsaLite is select quality, kiln-dried, end-grain balsa wood suitable as a structural core material in composite sandwich construction. BalsaLite balsa wood is a naturally renewable resource. The balsa plant (Ochroma lagopus) grows from seedling to mature balsa tree in 4-6 years and reaches heights up to 25 m (90 ft) before dying in 8-10 years. Tropical winds spread balsa seeds throughout the equatorial highlands of Ecuador where mature trees are harvested. The trees are then milled and kiln-dried. After being converted to BalsaLite, the product is supplied to Nida-Core your balsa wood supplier in the USA, Europe Mexico, France etc%u2026 and finely you. BalsaLite's end-grain orientation gives it exceptional compression and shear properties. As an added benefit, BalsaLite provides good thermal and acoustic insulation.

OCV™ Unidirectional Fabrics provide excellent strength and stiffness along the fiber direction. They also provide the highest ratio of axial strength to weight. This combination of properties makes Unidirectional Fabrics ideal for demanding applications with a high aspect ratio (length to width ratio) such as wind blades, poles, and stringers. These fabrics are also useful in applications where a discrete area requires additional strength or stiffness. Wrapping of existing structural components, such as columns and beams, with Unidirectional Fabrics could also greatly increase the lifespan and performance of these critical load-bearing members. These fabrics are also commonly used in FRP pipe and fittings for increased strength.
