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.
