Divinycell® H — High-Performance PVC Structural Core

Divinycell® H is a high-performance, closed-cell PVC core material engineered to deliver exceptional mechanical properties at an impressively low weight. With more than 75 years of global use across marine, transport, wind energy, civil infrastructure and industrial composites, Divinycell® H has earned a reputation as one of the world’s most reliable and versatile structural cores.

Engineered for demanding environments, Divinycell® H excels in applications subjected to fatigue, slamming and impact loads. Its unique formulation delivers outstanding shear strength, excellent adhesion/peel strength and superior fatigue resistance — making it a preferred choice for hulls, decks, superstructures, high-load panels, composite tooling and high-performance vehicle structures.

With low water absorption, excellent chemical resistance, very low resin uptake and strong thermal/acoustic insulation, Divinycell® H performs consistently in harsh marine, industrial, Defence and cryogenic conditions — including LNG insulation, blast-resistant structures and low-temperature applications where stability and safety are critical.

Thermoformable and easy to machine, Divinycell® H is widely used in Defence vessels, aerospace interior components, architectural façades, transport vehicles and advanced industrial structures. Available in a wide range of densities and finishing formats, it is fully compatible with epoxy, vinyl ester and polyester resin systems.

frequently asked questions

How does ATL tailor composite systems for different industries?

Every industry has distinct performance, compliance, and manufacturing requirements. ATL’s in-house chemists and engineers develop and refine epoxy systems, adhesives, and core materials to meet the specific demands of marine, defence, aerospace, automotive, industrial, civil, architectural, and sporting applications — ensuring every product delivers optimal strength, efficiency, and durability.

Can ATL customise materials for my project or process?

Yes. ATL offers custom formulation and process engineering support to align material performance with your production requirements — whether infusion, hand lay-up, lamination, bonding, or CNC-routed panel construction. Our technical team collaborates closely with customers to deliver precision-matched resin systems and structural solutions for unique applications.

Are ATL’s composite systems certified for high-performance applications?

Absolutely. ATL operates under an ISO 9001:2015-certified quality management system, with selected materials approved by DNV for use in structural and high-load applications. Every ATL system is manufactured to exacting standards of performance, consistency, and traceability to meet the demands of defence, industrial, and advanced engineering environments.

What makes ATL’s materials suitable for large-scale or structural builds?

ATL’s epoxy systems, structural panels, and composite cores are engineered for high strength-to-weight performance, dimensional stability, and fatigue resistance. These attributes make ATL materials ideal for large composite assemblies, modular structures, and precision-engineered components where long-term strength, weight reduction, and reliability are essential.

Does ATL offer sustainable or bio-based composite options?

Yes. ATL is committed to advancing sustainable composite technology, offering USDA-Certified Bio-Based epoxy systems and environmentally conscious materials that reduce waste, extend service life, and minimise environmental impact. Our ongoing R&D focuses on improving sustainability without compromising structural integrity or mechanical performance.

How can I select the right ATL system for my application?

Choosing the ideal composite system depends on your structure’s design, load requirements, manufacturing process, and environmental exposure. ATL’s in-house engineers and chemists provide tailored advice to ensure the correct combination of resin, core, adhesive, and surface technology for your project.
To discuss your application or request technical guidance, contact ATL’s Technical Team — we’ll help you identify the most effective and efficient composite solution for your build.
