Product introduction
This product is made of high-performance polyolefin material, produced by flash evaporation and spunbond process, and then processed by hot pressing compound process.
Heat shrinkage: <1.5% @100℃ 1h.
Tensile strength: 1750-2300kgf/cm2
Welding: Direct hot pressing or ultrasonic welding, melting point 110-120℃. It can also be bonded with an adhesive layer.
Material properties: hydrophobic grade 3-4. oleophobic grade 5-9
Proess:
1. Ultra-high molecular weight PO material---flash evaporation---spunbond---hot pressing. It can be directly used for welding, or compound viscose layer.
2. High-performance PO porous membrane--composite functional layer (adhesive layer or welding layer)
Product Specifications & Performance
Applications & advantages:
● UF grade aperture, effectively intercept germs. Aerosol, PM2.5. Reject liquid water and blood penetration.
● Used for masks. Protective clothing: better than SMS materials (meltblown & spunbond). No fiber shedding. Good breathability and moisture permeability.
● Excellent material and good compatibility. For food/medical ETO sterilization.
