At Zouch Converters Limited, we understand that effective filtration is about far more than simply catching dust or debris. It’s about safeguarding performance, protecting people and equipment, and keeping critical systems running reliably day after day.

From medical devices and gas systems to aquatic environments and cooking equipment, our world-class filter foams are designed to perform in demanding applications where you simply cannot afford to compromise.

What is filter foam?

Our filter foams are polyurethane-based materials, manufactured using either polyester or polyether polyols. Through a specialist process known as reticulation, the internal cell membranes of the foam are removed.

This transforms the foam into an open, net-like structure with highly consistent pores. Two key benefits come from this:

• Low flow restriction – Air, gas or liquid can pass through easily, helping systems operate efficiently.

• Particle capture – Dust, dirt and other unwanted particles are trapped within the foam’s cells, instead of entering your equipment or product.

The result is a lightweight, durable and highly effective filtration material that can be tailored to suit a wide range of performance requirements.

One principle, many applications

Although the core job of filtration foam is always the same – to allow water, air or gas to flow while removing contaminants – each application places different demands on the material.

Zouch filter foams are used across sectors including:

• Medical – To help ensure clean, controlled air or fluid flow in sensitive equipment and devices.

• Gas – To protect systems from particles that could damage valves, controls or sensors.

• Aquatic – To support water quality in filters and pumps, helping maintain cleaner environments.

• Cooking and food-related applications – To assist in managing grease, vapours and airborne particles in demanding kitchen conditions.

Because we offer a comprehensive range of foam grades and post-treatment options, we can support both highly specialised uses and more general filtration needs.

Advanced adhesive and coating technologies

As a converter and supplier of speciality, high-performance products, Zouch goes beyond the foam itself. We work with an extensive range of adhesive and coating technologies, including:

• Solvent-based systems

• Water-based systems

• Hot-melt technologies

• Rubber-based adhesives

Each option brings its own technical advantages. Across the range you’ll find different adhesive strengths, bonding characteristics and levels of conformability, as well as a variety of price points to suit your project and production requirements.

Whether you need a foam that bonds securely to metal, plastic, glass or painted surfaces, or you require a specific application method, we can help you select a solution that fits seamlessly into your manufacturing process.

World-class filtration foams, proven in industry

For more than a decade, Zouch Converters has been manufacturing and supplying filtration foams and post-treated products to industry-leading organisations in the UK and beyond.

Our customers choose us because we offer:

• Technical expertise – We understand the science behind filtration and the practical realities of using it in the field.

• A broad product offering – From fine to coarse pore sizes, flexible formats and specialist treatments, we can cover a wide range of performance needs.

• Reliable quality – Consistent materials, manufactured and converted to tight tolerances.

• Collaborative support – We work closely with design, engineering and procurement teams to ensure the chosen foam and adhesive system is right for both the application and the production line.

A partner for your next filtration challenge

Every project is different, and effective filtration is rarely a one-size-fits-all decision. That’s why our team takes the time to understand your environment, the media being filtered, the operating conditions and any regulatory or safety considerations.

From there, we can recommend the most suitable foam type, pore size, thickness, adhesive system and finishing options – helping you balance performance, durability and cost.

Whether you’re developing a new product or improving an existing design, Zouch Converters Limited is ready to help you filter out the noise and focus on what matters: dependable, high-quality performance.
