polyurethane filter foam

Description:

Filter foam also named reticulation 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.

Specifications:

Raw material: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

Applications:

communication equipment,home appliances,automotive industry

air-conditioner industry,hardware industry,medical equipment industry,physical education equipment

instrument tools,bags,furniture,children's educational toys,physical education equipment, house wares and so on.

It's divided into beginning effect filter foam,amid effect filter foam and high effect filter foam according to the porosity and usage.

Concretely,it can be used in filtering,dustproofing,dedusting and adsorbing,etc.
