Sustainable Foam
High-performance, eco-responsible foam for demanding applications
When sustainability matters as much as performance, Kewell Converters delivers. We’re proud to offer a carefully selected range of high-quality foam materials from trusted, responsible manufacturers such as Zotefoams and Apetek, chosen not only for their environmental credentials but also for their proven performance in mission-critical environments.
Whether you’re specifying foam inserts, gaskets, seals, or protective packaging, our sustainable foams offer you the strength, reliability and precision engineering you expect, without compromise.
Engineered for the toughest sectors. Now built for a greener future.
For over 50 years, Kewell Converters has specialised in bespoke foam fabrication for complex, high-value projects. Today, we continue to serve the aerospace, military, defence, and industrial sectors with sustainable foam solutions that meet both technical and environmental standards.
Every material we offer is selected based on its performance under pressure, from vibration resistance and thermal stability to durability in extreme operating conditions. Now, we apply the same scrutiny to sustainable foam materials, so you don’t have to compromise on quality to meet ESG goals or supplier mandates.
Sustainable foam options we offer
Ecozote® (from Zotefoams)
- Made with 30% recycled content

FAQs
Yes. All the sustainable foams we offer—such as Ecozote®, Stratocell® R and Arplank®—deliver performance on par with their non-recycled counterparts. They’re suitable for demanding applications including aerospace, defence, and industrial use.
Absolutely. Our experienced engineering team will work closely with you to recommend the best foam solution based on performance requirements, compliance, environmental goals, and budget. We’ll support you from material selection through to final part manufacture.
We hold stock of branded foams, including Zotefoams materials, enabling us to offer reliable lead times. For highly specialised or large-volume projects, we can also source materials as part of a managed supply chain process.
Yes. Many of the recycled-content foams we use meet the technical and regulatory standards expected in sectors like defence and aerospace. We regularly support projects requiring tight tolerances, consistent performance, and traceable sourcing.
We provide fully converted foam parts, custom foam inserts, gaskets, pads, and engineered shapes, all precision cut to your specification. We’re a foam converter, not just a material supplier, so you get complete, production-ready components.
