Preperse PE-S grade has similar physical properties to Preperse PE, which is also based on polyolefin carrier and granular type with properties of low-dusting and free-flow.
The difference between Preperse PE-M and PE-S is that, PE-S grade is targeting at applications request high FPV result, such as thin film etc. In order to achieve the FPV requirement for severe applications, twin-screw extruder and making mono masterbatch is necessary.
The common FPV of Preperse PE-S grade is ≤ 0.8 bar/g, based on below condition： Mesh number: 1400; Pigment content involved: 60g; Pigment % to resin: 8%.
