  • Reticulation – A lesson in research

Choose Our Reticulated Foam

Effective filtration is a key factor in the performance, efficiency, and maintenance of a broad range of applications from heating and ventilation (HVAC) systems to wastewater and aquatic filtration.

Ensuring the correct filtration media is used will not only achieve the best possible results but will also prolong the life of your equipment. Our extensive range of reticulated polyether and polyester foams are available in a range of porosities and offer the optimum combination of mechanical and biological filtration.

  • Polyester and Polyether Foams

Reticking all of the boxes

Now for the technical bit!

To create a completely open-cell foam the process of reticulation is used – this involves placing a block of closed-cell foam into a reactor, a mix of hydrogen and oxygen is then pressurized and ignited.

The resulting explosion blows out the cell walls without affecting the structural properties of the foam, the result is a completely porous material with a finely controlled cell structure which is graded by the pores per cubic inch.

  • Grading your best options

A Look At Our Diverse Range Of Reticulated Foam

At Foam Conversion we stock over 4000 sq feet of reticulated filter foam ranging from 10ppi – 90ppi and in a selection of different colours. Many of these grades are available with a fire-retardant additive making them ideal for industrial and domestic use.

Our in-house lamination facilities enable us to combine different porosities, creating a multi-layered composite material offering even greater levels of performance. All of our materials are available cut to your specific requirements with or without self-adhesive backing.

  • Cumulative skill and experience

The Best At Solving Complex Consumer Requirements

Reticulated polyether and polyester foams are manufactured using a CFC free process and contain no plasticizers. Polyether benefits from good resistance to chemicals, acids and oxygen and is widely used in the wastewater and aquatic industries.

Polyester is less resistant to ageing than polyether but is available in a wider range of porosities, has a more uniform cell structure and is available in fire retardant variations making it ideal for industrial oil and air filtration.

  • We’re all that you need
