Divinycell® PET PL — High-Performance Recycled PET Structural Core

Divinycell® PET PL is DIAB’s next-generation high-performance PET core material engineered to optimise strength, weight and sustainability in modern composite structures. Manufactured from post-industry recycled PET, this thermoplastic, closed-cell foam core delivers excellent mechanical performance while supporting circular material use and reduced environmental impact.

Designed for infusion, RTM, prepreg and press-bonding processes, Divinycell® PET PL offers ultra-low resin uptake, high compression and shear strength, and superior dimensional stability at elevated temperatures. These characteristics allow manufacturers to achieve lighter, stronger and more cost-efficient components — without the need for additional surface treatments.

With excellent chemical resistance, good screw retention (particularly in PL230) and reliable peel strength, Divinycell® PET PL is ideal for marine, transport, wind energy, industrial, architectural and general composite applications where performance, sustainability and processing efficiency are critical.

Compatible with all a large range of finishing options and available in precision-cut kits through ATL Composites, Divinycell® PET PL provides a streamlined, production-ready solution for advanced composite manufacturing.

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.
