Product Introduction
1、 Basic attributes
Polypropylene Non Woven Filter Fabric is a porous fabric made from polypropylene resin through non-woven processes such as meltblown and spunbond. Its physical properties are manifested as a density of about 0.9g/cm ³ and a lightweight texture; The chemical properties are inert materials, non-toxic, odorless, acid and alkali resistant, and organic solvents (except for strong oxidants). It can withstand high temperatures of 120 ℃ in the short term and has stable performance in low-temperature environments. The material structure is a three-dimensional mesh, with fiber diameters ranging from micrometers to nanometers, uniform pore distribution, and a certain tensile strength and tear strength, making it easy to process and shape.
2、 Core functions
As a filtering medium, its core function is to efficiently separate impurities in fluids, including:
Particle interception: Through the mechanical barrier and adsorption effect of fiber mesh structure, different particle size pollutants such as dust, bacteria, aerosols, suspended solids, etc. in air or liquid are captured. The filtration efficiency can be adjusted through process to reach high standards such as N95 and pharmaceutical grade.
Fluid purification circulation: While achieving efficient filtration, it ensures smooth passage of air or liquid, maintains low resistance and high flow operation, and reduces energy consumption of the filtration system。
Safety protection: In medical, food and other scenarios, physical barriers and sterilization stability are used to block the spread of harmful substances and ensure contact safety.
3、 Main features
Efficient and low resistance balance: The porous structure ensures high filtration efficiency and excellent breathability, reducing fluid resistance by 30% -50% compared to traditional materials, balancing purification effect and system energy consumption.
Strong stability: Good weather resistance, not easily degraded or deformed in humid, high and low temperature environments; High chemical stability, suitable for various complex working conditions.
Safe and easy to handle: non-toxic and biocompatible, can tolerate multiple sterilization methods, and meets medical and food contact safety standards; After disposal, it can be recycled through melting and regeneration.
Excellent cost and flexibility: With a wide range of raw material sources, high automation production efficiency, and controllable costs; Can be processed into various forms such as filter bags and filters, supporting customized functions such as electrostatic polarization and antibacterial
