PTFE Waterproof Breathable Membrane

Our PTFE Waterproof Breathable Membrane is a high-performance Waterproof breathable material designed to provide 100% water resistance while allowing vapor and air to pass through. As a professional PTFE membrane manufacturer and global waterproof breathable material supplier, we produce PTFE membrane and ePTFE membrane solutions widely used in outdoor clothing, industrial filtration, electronics, and medical protective equipment.

This PTFE breathable membrane offers an ideal balance of waterproofing, breathability, and chemical resistance, making it a versatile choice for a wide range of applications where moisture control and protection are critical.

Core Advantages

• Superior Waterproofing
  The microporous PTFE waterproof membrane effectively blocks liquid water while maintaining high vapor permeability.

• Excellent Breathability
  Advanced ePTFE membrane structure allows moisture vapor to escape, keeping fabrics dry and comfortable.

• Chemical & Temperature Resistance
  Resistant to acids, alkalis, solvents, and capable of withstanding temperatures from -200°C to +250°C.

• Durable & UV-Resistant
  Long service life, stable performance in outdoor environments, and protection against UV degradation.

• Lightweight & Flexible
  Easy to laminate with textiles and films without compromising softness or flexibility.

Typical Applications

• Outdoor Apparel & Footwear – Jackets, shoes, gloves, and gear requiring water protection and breathability.

• Medical Protective Fabrics – Surgical gowns, barrier fabrics, and disposable protective clothing.

• Filtration Systems – Air and liquid filtration membranes, dust collection systems.

• Electronics & Enclosure Venting – Protects sensitive components while allowing pressure equalization.

• Acoustic Membranes – Waterproof speaker membranes, microphone protection.

• Industrial Equipment – Tents, tarpaulins, waterproof covers, and venting systems.

Frequently Asked Questions (FAQ)

Q1: What is the difference between PTFE membrane and ePTFE membrane?
A: PTFE membrane refers to the base material, while ePTFE membrane (expanded PTFE) is a microporous form created by stretching PTFE, resulting in high breathability and superior waterproof performance.

Q2: Can PTFE waterproof breathable membrane be laminated with fabrics?
A: Yes, as a PTFE membrane manufacturer, we provide membranes suitable for direct lamination with textiles, ideal for making waterproof breathable jackets and footwear.

Q3: What industries benefit most from PTFE breathable membrane?
A: Outdoor gear, medical protective wear, filtration systems, electronics venting, and industrial waterproof covers.

Q4: Do you offer custom sizes and properties?
A: Absolutely. As a global waterproof breathable material supplier, we customize thickness, pore size, and air permeability to meet your specific application requirements.
