Polipleet Media is 100% polyester spun bound. It is created by having two different polyester resins continuously sprayed through miniature nozzles onto a moving web. One of the resins has a slightly lower melting point. The mat is drawn through heated roll - ers that compact and fuse the fibers together, forming surface patters into both sides of the media.
The resulting media has the following characteristics:
- Strong continuous fibers
- Small fiber size
- Burst strength similar to felt
- Dense, thick mat
- Small pore size
- Strength in all directions
- Thermally stable
- Same permeability as needled felt.
