Merryweather is an authorized distributor of Foamex Filter Foam (SIF), SIF Felt, SIF-PVC (polyvinyl coated foam), Custom Felt Non-reticulated and non-reticulated ethers and esters (Custom), acoustic (Hyfonic), FR (Pyrell), Safety, low perm (LP) and laminated (LAM) products.
SIF Filter Foams are flexible networks of open cells (three dimensional skeletal strands), like miniature scaffolding, mesh or screens, available in various pore sizes (3 to 110 pores per inch), compressions (2 to 20 times original thickness) and grades to achieve varied physical properties. Larger, uncompressed pore sizes offer low resistance and pressure drop, large holding capacity with 97% void volume and sound permeability. Smaller compressed pore sizes decrease the particle size filtered and increase resistance to fluid flow and absorption of liquids and higher frequency sounds.
Functions include filtration of dust or contaminates from air, gas, liquids, aerosols or gasoline; baffling, reservoiring, wicking, buffing, applying or demisting oils, soaps, waxes or inks (up to 2300 square feet of surface area per cubic foot of foam); humidification or evaporative media, drainable cushioning, oil/water separation, coalescing, oil clean up and acoustical absorption or permeability.
SIF Felt is made from reticulated polyester or polyether foam by compressing with pressure and heat. The compression ratio (initial foam thickness / final felt thickness), also called firmness , effects the particle size to be filtered, resistance to fluid flow, wicking, reservoiring and increases physical strength properties. Variables can be adjusted for specific applications.
SIF-PVC coated foam resists chemical attack and has greater tear strength and compression deflection than uncoated foam. NON-RETICULATED POLYURETHANES
Protective Cushioning Gasketing Sound Absorption Packaging
Flexible polyurethanes can be used in a variety of applications from acoustical absorption to vibration dampening. Merryweather inventories numerous densities for varying applications. Charcoal and white are standard but color matches are possible. If there are specifications you need to meet, please contact us and we will research the materials required.
