PU Ester foam types

offer

• a very uniform cell structure ranging from 8 to 100 ppi (pores per inch)
• good UV resistance
• high resistance to oils, fats and organic solvents
• physiologically safe

Our ester-based filter foams are ideal to be used as particle filters in air-conditioning and ventilation systems, in domestic appliances such as vacuum cleaners, or as a matrix for impregnating foam ceramic filters or silicone foams.

Some possible applications include:

• air-conditioning and ventilation technology for mechanically acting air filters
• textile industry: for the manufacture of breathable laminates
• automotive industry: for specialised filter ventilation systems
• covers for microphones, hi-fi headphones and the front panels of loudspeaker enclosures
• consumer goods industry: within the upholstery sector
• thermal-, refrigeration- and sound insulation-sectors
• filtration, distribution, gas injection and venting
• air curtain systems
• cosmetics industry
• liquids, gases and exhaust air
• respiratory protection equipment, with impregnated activated carbon
• surface air filters, etc., with hydrophilic/hydrophobic impregnations
