Divinycell® HM — Ultra-Tough Structural Core for High-Performance Marine Composites

Divinycell® HM is a high-performance structural PVC core engineered for applications where exceptional toughness, impact resistance and fatigue performance are essential. Designed specifically for high-speed marine hulls, slamming areas and dynamic load environments, Divinycell® HM delivers a unique combination of very high shear strength and outstanding shear elongation, resulting in a core material capable of absorbing extreme energy without failure.

Its advanced formulation meets — and exceeds — the requirements of ISO 12215, GL and ABS rules, allowing designers to reduce safety factors and achieve lighter, stronger structures without compromising reliability. The material’s high compressive strength provides remarkable resistance to denting, skin wrinkling and point loading, enabling thin-skin laminates without sacrificing durability.

Divinycell® HM also offers excellent thermal stability, making it ideal for dark-coloured hulls and structures where higher processing or operating temperatures can lead to print-through issues. Thermoformable, easy to machine and compatible with all major resin systems, Divinycell® HM is the preferred choice for premium performance in marine, industrial and demanding composite applications.

Divinycell® HM is approved by:

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.
