Reticulated Polyester Foam

Polyester reticulated foam, available as sheets, cut pads, cylinders and sewn on to wire frames. From 10ppi to 60ppi.

Product Overview

Reticulated Foams are formed by a de-membraning process which creates totally open cell foam, a good product for air filtration having low pressure resistance and good dust holding property.

Reticulated foam is graded in pores. This is measured by counting cells per inch; grades start at 10ppi and end in 60ppi.

Polyester foams are suitable for air filtration.

Foam sheets can be converted into your required pad size, whilst different pore sizes bonded together will give two stage filtration, expanded mesh can be fixed between the pads to make a more rigid panel if required.

Foam pads can also be formed into cylinders, cones and other shapes, with metal mesh stiffeners if required.

Our reticulated foam pads can be glued together to form a dual-density pad, for two-stage filtration, with a metal mesh stiffener if required for rigidity. Pull tags can be attached to these filters.

Various impregnations, for stiffening or enhanced V-0 flame-retardancy, or carbon impregnation are available, please enquire.
