DIVINYCELL H

Divinycell H - Excellent mechanical properties to low weight

This unique PVC formulation yields impressive mechanical performance to a low weight. Divinycell H has a proven track record in virtually every application area where sandwich composites are employed, including the marine (leisure, military and commercial), land transportation, wind energy, civil engineering/infrastructure and general industrial markets.

Divinycell H is ideal for applications subject to fatigue, slamming or impact loads. Other key features include excellent adhesion/peel strength, excellent chemical resistance, low water absorption and good thermal/acoustic insulation. It is compatible with virtually all commonly used resin and manufacturing methods.

Divinycell H – excellent mechanical properties at low weight

Divinycell H gives you a closed-cell PVC foam core engineered to deliver excellent mechanical properties at a low weight. This unique PVC formulation has a proven track record across virtually every application where sandwich composites are used, from marine and wind energy to land transportation, civil engineering and general industrial structures.

You can rely on Divinycell H wherever your structure faces fatigue, slamming or impact loads, since the material keeps its mechanical performance under repeated stress. It also offers excellent adhesion and peel strength, good chemical resistance, low water absorption and reliable thermal and acoustic insulation.

Divinycell H is compatible with virtually all common resin systems and manufacturing methods, including hand lamination, vacuum infusion and prepreg processing. That flexibility means you can specify Divinycell H foam core without redesigning your existing production line.

Divinycell H grades and properties (H45–H250)

Divinycell H comes in eight densities, from H45 to H250, so you can match weight, stiffness and strength to the load each part of your structure actually carries. The table below summarises the nominal mechanical properties for every grade, based on our published datasheet.

Divinycell H stays dimensionally stable across a continuous service range of -200°C to +70°C, and withstands short-term processing temperatures of up to 90°C for H45–H80 or 110°C for H100–H250. For the full property set, including tensile values, minimum guaranteed properties and thermal conductivity, download the datasheet from our Brochures, Certificates & Datasheets page.

Classification society approval you can build on

Divinycell H carries DNV type approval, giving you third-party verified documentation to take straight into your marine and offshore certification process. That's one reason Divinycell H has become a standard specification for classification-society-approved sandwich structures in commercial and naval vessels.

Where to use Divinycell H

In marine, Divinycell H helps you build light, fast and tough boats and vessels, from sailing yachts to commercial and navy vessels, without compromising on slamming resistance. Visit our Marine page to see how other builders specify it across hull, deck and bulkhead structures.

In wind energy, Divinycell H reduces the weight and total cost of blades and other composite parts, helping you lower the levelized cost of energy. Explore our Wind energy page for grade recommendations by blade section and manufacturing process.

You'll also find Divinycell H foam core specified in land transportation, civil engineering and infrastructure, and general industrial structures that need a lightweight, flexible and durable sandwich core. Use our Core Selection Guide to check a grade against your own load case before you order.

How Divinycell H compares to HP, HT and HM

Divinycell H is our all-round, general-purpose PVC foam core, which makes it the right starting point for most sandwich structures. If your project needs higher heat resistance, a tougher grade for high-pressure processing, or better fire performance, our Divinycell HP, HT and HM grades build on the same PVC chemistry for those specific demands.
