Zkefoam polyurethane filter cotton plays an indispensable role
Polyurethane filter cotton, also known as polyurethane sponge, polyether filter cotton, mesh sponge, bursting sponge, or open-cell sponge, is a high-tech filter material made from ordinary open-cell soft foam through a special bursting process.
This process removes the original thin film or wall membrane between the foam network, resulting in an ideal main skeleton structure mesh sponge. This gives it characteristics such as high porosity, good air permeability, high compressive strength, and maintains permanent elasticity.
Advantages of Zkefoam polyurethane filter cotton
<1> Excellent physical properties: This mesh sponge has a porosity of up to 97%, exhibiting excellent air permeability, good softness, and high mechanical strength. As a filter material, it has the advantages of low flow resistance and high filtration efficiency, effectively filtering out fine particulate matter.
<2> Wide range of applications: This product can be used in air filters, oil and water filters, ceramic filter substrates and other fields, covering automotive filters, filtration equipment, aquariums, gas masks, air conditioning purification, high breathability seat cushions, mattresses and industrial dust protection scenarios.
<3> Customizable Features: We can customize filter sponges with pore sizes ranging from 10-60 PPI (PPI is a unit of measurement for sponge pore size, referring to the number of pores per inch). They can be processed into cylindrical, hollow, square, and other special shapes according to requirements and samples. Flame-retardant mesh sponges can also be produced according to customer specifications.
Zkefoam polyurethane filter cotton has diverse applications
Polyurethane filter cotton has a wide range of applications, covering multiple fields from civilian to industrial:
1. In the air purification field, this product can be used as a pre-filter or medium-efficiency filter element in household air conditioners, central air conditioning systems, household/commercial air purifiers, range hoods, fresh air systems, automotive air conditioning, etc., effectively removing pollen, dust, and other particulate matter. The product has an opening rate of up to 97%, forming a highly efficient filtration path.
2. In HVAC equipment, it can be used in household air conditioners, central air conditioning systems, air conditioning fans, cooling towers, air source heat pump units, fan coil units, etc., as a filter layer to prevent dust from entering, reduce noise, protect internal components, and improve air quality. This product has good elasticity, high tensile strength, high compressive strength, and strong resilience.
3. In water treatment and filtration, it is suitable for aquariums, water pumps, water purifiers, washing machines, swimming pools, bathtubs, faucets, shower heads, etc., for water pre-filtration, nitrifying bacteria cultivation, waste decomposition in water, and water quality improvement.
4. In industrial dust control and protection, it is suitable for air compressors, blowers, motor cabinets, industrial machinery, precision instruments, and other equipment. It filters dust, protects critical mechanical components, reduces wear, and has sound-absorbing properties. This product has good oil and chemical resistance, and its performance does not decrease after cleaning.
5. In the transportation sector, it is suitable for automotive/motorcycle air filters, automotive air conditioners, air purifiers, car audio systems, and other equipment. It filters the air inside the vehicle, effectively protecting the engine. This product is easy to clean, can be repeatedly washed, and has a long service life.
6. In other fields, it is suitable for speaker housings, respirators, model making, and activated carbon carriers. It can be used as sound-absorbing material for speaker housings, filter layers for masks, and frames or carriers for craft models. The product’s pore size (10-60 PPI), color, and shape (sheet/block/cylindrical, etc.) can all be customized.
