10 ppi 60 ppi saltwater fish tank aquarium filter sponge bio filter sponge

Has excellent resistance to water and humidity, and is therefore ideal for water and air filtration. The calibrated cell size and homogenous cellular structure allow these materials to be used in biotechnological and environmental applications; the high surface area of the foam supports the growth of micro organisms. These filter foams are resistant to mild acids and alkalis, salt water, fuel, organic chemicals, oils, lubricants, soaps and detergents.

Product Description :

Filter foamalso named reticulated foam, blasting foam. Filter foam is made of ordinary open cell through net processing. Opening ratio of filter reaches to 90%~98%, it’s very suitable for filteration with permeability, well flexibility, well machanical strength.

Application :

Industrial waste water treatment, water pollution control, mechanical filtration and pre-filtration of air and water. Although ideal for water filtration, polyether filter foams are also suitable for humidifiers, ventilation systems and acoustic foam for loudspeakers. These foams can be washed and rinsed for re-use many times.


  • Raw material: (PU Foam) polyether or polyester foam
  • Porosity: 10~60PPI
  • Other available auxiliary functions: mould preventing, asorbing harmful gases, fire retardant,etc.
  • Available shapes: sheet,strip,ball,roller,tube,other customized shapes

Cell Structure:

Reticulated filter foam是一个depth-loading过滤器,而不是a surface-loading filter, essentially trapping dust particles within its cells.
The cell structure of filter sponge is remarkable in that each cell has a dodecahedron shape (12 sided), the cell’s walls or “struts” are comprised entirely of organic polymers (polyurethane, polyether, polyester) and the empty space or “windows,” between each strut, comprise 95% – 98% of the filter foam’s mass.
The size, shape & distribution of cells within filter foam can be manipulated during manufacture to provide precisely the desired porosity level, measured in PPI(pores per inch).

10PPI – 35PPI pore densities, approximately full scale

Foam Types and Uses:

Conventional PU foam (padding foam)for padding and packaging – the standard foam. These are available in different densities: A low density foam is suitable for use in making children’s games or leg-rests – one way to look at it is that it is more suitable as a backrests than as a seat cushion. The 35/55 grade is THE standard foam for all padding purposes including reclining cushions and seat cushions. Please note that a foam with a higher density should be used, for instance, in the food services industry, in particular for seat cushions that must withstand heavy use or for overlay materials (cushions) that will have to endure a lot of punishment.
Our range of PU foams can be subdivided into the following categories:

Cold foamis an especially high quality and durable PU foam that is particularly elastic. It is often used for making mattresses or extremely comfortable and high quality seat or bench cushions.

Composite foam是一个特别坚定的泡沫。它很容易distinguished from other foams by its mottled appearance. Applications: thin seat cushions, bar stool or motorcycle saddle cushions, acoustic insulation, church kneelers, cushions for ale benches, etc.

Visco elastic foamhas a cotton wool kind of consistency, is extremely soft and point elastic. It is especially great for making seat cushions for things like wheel chairs where the time spent sitting will be exceedingly long and comfort is a must. Its primary use, however, is as a mattress topper for increased comfort when sleeping.

Convoluted (egg crate) foamhas an unusual three-dimensional surface that is ideal for packaging and acoustic applications.

Filter foam, which is endowed with a special permeability during the production process, is, as a result, used for technical purposes (we carry it primarily as a model making material).

Lighter weight, less firm soft foams tend to be used in greater thicknesses because they are so easy to compress completely, which of course eventually robs them of the padding property. Heavier, firmer foams (for example, composite foam), on the other hand, are usually used in thinner profiles because their greater firmness means you do not need such a thick cushion to achieve comfort. Its greater density, however, means that it will be more expensive.

Whatever you need, contact us and we will be pleased to help.×
Our sales team works closely with you to understand your products, business and vision. We review both internal and external factors, from product information to environmental factors involved in production, packaging and testing requirements. We form well considered opinions as a basis for recommending, improving and strengthening your products, before choosing the right format and manufacturing base.

Once our sales team has gathered all the information we then hand the project over to our sourcing team who will look carefully at the project needs and objectives to find the right location to manufacture the goods. They will look at issues of price, quality and delivery times before making a decision.

International companies also require a high standard of social, ethical and environmental compliance which must be passed on to their customers. We pride ourselves on only using factories that can pass social, ethical and environmental compliance audits, carried out by recognized international testing companies.×
Within our company we have a vast understanding of client’s requests involving packaging. From designing detailed items to undertaking in-depth solutions we offer brand awareness with complex ideas to help improve packaging so your customers feel they have been offered creative and informative solutions. Master Sponge always considers the environmental impact of materials used in packaging and researches new and improved ways of communicating the message to the end user.

We are able to offer a variety of different packaging options, such as PP bag with coloured card, PE bag with colored card, Blister (Clamshell), PVC box, etc, your logo and company name are able to be placed on the packaging, and/or on products as well.

Master Sponge can therefore offer a full through the line service from designing and developing new products, through the stages of mass production, packing and delivery to the clients doorstep.×
At Master Sponge we understand the need for strict quality guidelines to be imprinted into our organizational structure. China has a distinct lack of professionalism when it comes to issues of quality. With our quality control office sustained by professionally trained staff, overseen directly by our senior management and located in the heart of the manufacturing district; we are able to demand the highest standard of quality from our suppliers.

Quality starts with organization; we have many factories wishing to work with us but are very selective when choosing them. We send our trained audit technician who will look round the factory to assess whether it can pass international ethical & social inspections. Once this is done we will look at the machinery and make sample products to ensure the quality and manufacturing process is to our standards. We then talk to the management to assess whether or not they are people who we can discuss and solve complex problems with.

Once this is complete we will begin to produce products by placing our own Quality Control representative to oversee all production.×
