Divinycell® HP — High-Temperature Structural Core for Advanced Composite Processing

Divinycell® HP is a high-performance PVC structural core engineered to meet the demands of elevated-temperature composite processing, including low–medium temperature prepreg systems, infusion and other advanced manufacturing methods. Its unique polymer formulation provides an outstanding balance of strength, toughness and thermal stability at an exceptionally low weight.

Designed for applications where both processing temperature and in-service heat exposure are critical, Divinycell® HP retains a high percentage of its mechanical properties even after long-term exposure to elevated ambient temperatures. The material offers excellent stiffness-to-weight performance, high elongation to break, strong ductility and reliable adhesion/peel strength — ensuring dependable performance across demanding structural environments.

With excellent chemical resistance, very low water absorption, low resin uptake and reliable thermal/acoustic insulation capability, Divinycell® HP provides durable long-term performance in marine, wind energy, industrial, defence, architectural and high-performance vehicle structures.

Thermoformable, easy to machine and compatible with all common resin systems, Divinycell® HP enables efficient fabrication while meeting the stringent requirements of high-temperature composite production.

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.
