Sub-micron air filtration ePTFE laminate
Huzhou Kaili's sub-micron ePTFE (expanded Polytetrafluoroethylene) laminates represent the pinnacle of air filtration technology. By bonding an ultra-thin, microporous ePTFE membrane to high-quality synthetic substrates, we create a filtration media capable of capturing 99.9% to 99.999% of particulates as small as 0.1 microns.
Produced in our 3,000m² facility in the Yangtze River Delta fluoromaterial cluster, our laminates are engineered to provide maximum air purity with the lowest possible energy consumption.

Key Performance Benefits
- HEPA & ULPA Performance: Our membranes feature a highly controlled pore size distribution, allowing for efficient capture of sub-micron particles, including viruses, bacteria, and fine industrial dust.
- Low Resistance / High Airflow: The unique 3D nodal structure of ePTFE offers significantly lower resistance to airflow compared to traditional fiberglass or meltblown media, leading to substantial energy savings in HVAC and cleanroom systems.
- Surface Filtration Efficiency: Unlike depth-loading media that clogs over time, our ePTFE laminate captures particles on the surface. This enables easy cleaning and prevents "pressure drop spikes" during operation.
- Thermal & Chemical Stability: Operating stably from -190°C to +260°C, our laminates resist degradation from moisture, corrosive gases, and harsh cleaning agents.
- Hydrophobic Protection: Naturally repels water and moisture, preventing the growth of mold or bacteria within the filtration layers.
Targeted Applications
- Semiconductor & Electronics: Cleanroom ceiling modules and specialized tool filtration for particulate-free manufacturing.
- Pharmaceutical & Healthcare: Sterile air filtration for surgical suites, isolation rooms, and drug manufacturing.
- High-End HVAC Systems: Energy-efficient filtration for premium commercial buildings and laboratory environments.
- Vacuum Cleaners & Appliances: High-performance HEPA filters for allergy-grade domestic and industrial vacuums.
- Industrial Gas Turbines: Protecting sensitive turbine blades from fine salt and dust particles in coastal or desert environments.
