The perfect PU for your application

Finding the ideal PU foam for your needs may seem simple enough, but the world of polyurethane foam is a vast and complicated one as PU is an umbrella term that covers two main groups - polyether and polyester - both of which encompass thousands of different grades and materials, all with their own unique properties.

With the immense variety of PU foams available, ensuring the right PU foam is used to meet the exact demands and application of the end product is vital. This is where Technical Foam Services' experience and expertise sets us apart from other foam conversion companies.

Having been in business since 1990, at Technical Foam Services we have the expertise, the know-how and the relationships with the world's leading raw material suppliers to ensure that the PU foam products we develop and manufacture for you will meet all of the required specifications and performance criteria, while also offering the most cost-effective solution to your needs.

Vital expertise in PU performance

Our expert foam and technical engineers can identify the precise type of polyurethane foam grade and specification to meet your demands, considering every aspect of the process including how it will react in situ and stand the test of time.

We stock an astounding 300-plus grades of flexible foam covering all forms of PU and we also work closely with the raw materials suppliers when a new grade is required. We can also design and build bespoke machinery and tooling to ensure that the PU foam products we supply are fit for purpose and second to none.

Technical PU foams

Although all PU foams could be described as "technical", some are viewed as technical product groups as a result of their specific properties. These include reticulated foams and memory foams.

You can find out more about these specific PU foams on our dedicated pages.

Choosing the best

We view our customers, both old and new, as partners, not simply clients, working together to produce the optimum products for their needs.

All we need is for you to tell us as much as you can about the features you'd like to have. These include:

Choosing the best polyester foams for your needs

At Technical Foam Services we supply a wide range of different polyurethane, or Pu foams; the majority of which are open cell foams with a polyester base or polyether compound. There are thousands of these which we supply for a variety of specialist areas, such as hospitals and the auto trade.

What are flexible foams?

The Pu foams we manufacture and convert at Technical Foam Services are flexible, not rigid. In fact, practically all flexible foams are polyurethane, which are divided into polyether and polyester foams. Both are open cell foams, and are used in a wide variety of markets. Improvements in manufacturing technology now mean that polyester foams can be made in closed cell format, too.

Flexible foams have numerous benefits. They are resilient, adaptable, easy to cut and available in various densities and thicknesses to cater to different purposes.

Explaining open cell foams

Polyester or polyether foams have an "open cell" structure. This means they have a soft texture and can be moulded. During the manufacturing process, the bubbles of Pu foams are broken and the spaces filled with air, thus making them suitable for furniture and packaging.

Open cell foams lack the strength and density of polyether foams made in closed cell format, but are far more flexible and elastic; hence why they are also called flexible foams. Closed-cell Pu foams are rigid, and used for applications where flotation is important e.g. buoyancy aids and swim equipment.

Using flexible foams to quieten things down

Open cell foams offer superb sound absorbency, and are widely used wherever there's a need for soundproofing or sound absorbency. Industries - including the music industry - use our flexible foams to both block sound and enhance it.

Open cell foams work by trapping sound waves. As soundproofing products, they are used in walls, ceilings, doors and windows to block airborne noise from traffic, loud music, voices etc. However, they are also used to improve acoustics by absorbing sound, thus reducing echo and reverb. A sound-recording studio might install sound-proofing polyester foams in the walls and doors, and acoustic foams in the loudspeakers and recording equipment.

Reticulated polyether foams

These are Pu foams which have had their cells blown apart with explosive gas to give a consistently open cellular size, i.e. the open cells of the flexible foams are modified. They are predominantly used for filtration products.

Reticulated polyester foams are normally used for air filters. We supply polyester foams for use in motorcycles, cars, trucks and even trains and buses. Reticulated polyether foams, on the other hand, are always used in water filters. We at Technical Foam Services also supply reticulated polyurethane for more unusual applications; for example, the foam that is used with ceramic filters in foundries.

Polyether foams each have a unique chemical structure that gives them special characteristics. It's important you select the right foam for your needs. Luckily, at Technical Foam Services we have a thorough in-depth understanding of the chemical processes involved in the manufacture of our polyester and polyether foams, and are always happy to share this knowledge with our customers.
