​Stationery application PP foam sheet/board extrusion machinery , PP micro foam board extrusion machine adopts T-type die head and three roller calendars technology to produce high smoothly and highly flat micro foam sheets. It is foamed by add some foaming additives , also called chemical foamed . This kind of foam board can be single layer extrusion , and also can be double layer AB type and 3 layers ABA/AB type .

Meltblown technology is one of the most effective ways to make very fine, highly efficient filter media. A 100% eco-friendly recycl air filter polypropylene wipe nonwoven fabric meltblown has a diameter of less than 10µm, many times finer than a human hair, which has a diameter of 120µm, or a cellulose fiber of about 50µm.

The raw material is a thermo-plastic synthetic material which is melted and forced through an extruder consisting of a very large number of tiny nozzles. Immediately after exiting the nozzles, the individual filaments are blown by hot air in the same direction while still in their semi-melted state, extending them and creating very fine, endless fibers, within a few milliseconds.

Using this dry-laid process, Neenah Gessner can produce media with weights from 10 – 300g/m².

Alternatively, the melt blown can be directly applied to a carrier media [cellulose or spunbond , producing combination media in one step.

Additional there are many options to choose: fiber diameter, thickness, grammage, FDA-conformity, haptic surface design, resistance to chemicals, heat resistance, compostability, dust loading, low shedding surface polarity, UV-Protection, antibacterial, colors, elctrocharging and antistatics
