What is the difference between microporous PTFE and monolithic TPU membranes?

Microporous PTFE membranes feature microscopic pores smaller than water droplets but larger than water vapor molecules for superior breathability. Monolithic TPU membranes are solid hydrophilic polymer barriers offering 100% windproof protection and elastic durability.

What waterproof hydrostatic head rating does Zhanfa 3L fabric achieve?

Our 3-layer performance fabrics achieve hydrostatic head ratings from 15,000mm up to 28,000mm (ISO 811:2018 standard), ensuring complete rain and snow barrier protection under severe pressure.

Textile Science & 3-Layer Membrane Technology

Guangzhou Zhanfa Textile integrates polymer membrane synthesis with precision hot-melt lamination to engineer technical fabrics capable of withstanding extreme mountaineering conditions, hurricane precipitation, and heavy abrasion.

What Are the Core Membrane Types We Deploy?

Expanded Microporous PTFE

Contains over 1.4 billion microscopic pores per square centimeter. Pores are 20,000 times smaller than a water droplet, guaranteeing 28,000 mm waterproof hydrostatic head (ISO 811:2018).

Hydrophilic Monolithic TPU

Solid non-porous polymer that transports vapor via molecular diffusion, remaining completely impervious to wind, oils, and salt crystallization down to -35°C.

"Tested according to ISO 811:2018 and JIS L1099 Method B1, our 3-layer composites deliver laboratory-verified storm barrier performance with 20,000 g/m²/24h MVTR breathability."
