High-quality, engineered foam sponges for demanding industries
At Kewell Converters, we specialise in supplying and fabricating high-quality foam sponges that are engineered for performance across the most challenging environments. With over 50 years of foam conversion expertise, we understand how critical it is to deliver bespoke foam solutions that meet strict specifications, withstand extreme conditions, and provide real-world durability.
From military-grade protective foam to precision-engineered aerospace components, Kewell Converters partners with procurement specialists, quality managers, production teams, and engineers to deliver tailored, high-performance foam parts and custom foam solutions that solve complex challenges.
What are foam sponges and why are they essential?
Foam sponges — typically made from cellulose foam or high-grade synthetic foams — combine lightweight structure, high absorbency, and excellent resilience. They’re ideal for demanding environments where performance, durability, and precision are non-negotiable.
Our foam sponges are used across industries for:
- Sealing and cushioning components
- Absorbing impact and vibration
- Managing fluid retention and transfer
- Creating protective foam inserts and packaging
- Providing soft-touch cleaning solutions for delicate surfaces
At Kewell Converters, we do more than supplying sponge sheets — we engineer bespoke foam shapes and custom foam parts to your exact requirements, optimising material selection, thickness, and design to maximise performance and value.
