Gaskets & Seals
Precision-engineered foam components for protection, performance and durability in demanding environments
At Kewell Converters, we’ve spent over 50 years designing and manufacturing foam gaskets and seals for customers operating in some of the most demanding sectors in the world – including military, defence, aerospace, and high-end industrial markets. When reliability and performance under pressure are critical, procurement and production teams turn to us for foam conversion expertise, precision engineering, and problem-solving design.
Our foam gaskets and seals are designed to protect against water ingress, chemical exposure, vibration, and extreme temperatures – with tailored designs and material specifications to match your exact requirements.
High-performance foam gaskets and seals – made to order
Every gasket and seal we produce is engineered from high-quality foam materials selected for the performance demands of your application. We offer:
- Closed-cell foam gaskets that are water repellent and UV-resistant
- Low and high-temperature foam seals for aerospace and industrial applications
- Chemically resistant seals for use in electronics and hazardous environments
Materials & capabilities
We work with a wide selection of specialty foams.
We supply foam parts with or without adhesive backing, and can laminate layers to increase thickness or modify performance characteristics. Our conversion processes include:
- Reel-to-reel and CNC slitting
- Guillotine cutting (up to 1 metre wide)
- Precision die-cutting
- Lamination and finishing for production-ready parts
ZOTEK® F (PVDF)
offers excellent chemical resistance, thermal stability to 160°C, and is approved by NASA and FDA , ideal for premium gaskets
PLASTAZOTE® & EVAZOTE®
lightweight, shock-absorbent, and available in multiple densities and colours.
EPDM, Neoprene, Silicone
for enhanced sealing, temperature resistance, and compliance with industry standards.
Applications of our foam gaskets and seals
Our foam gaskets and seals are used to:
- Prevent air, water, dust, or chemical ingress
- Reduce vibration and harshness in assemblies
- Cushion components against impact
- Maintain insulation or pressure in high-spec systems
Serving high-spec industries
We regularly supply components for use in a variety of industries.
