Poly-propylene (PP)
UPEX Dry Biaxial PP is Unrivaled Performance, the Core of Next-Generation Technology.
Poly-propylene (PP) membrane
Upex Co., Ltd. (“Upex”) is the pioneer that introduced the industry's first unique dry biaxial manufacturing technology, delivering exceptional value to clients through low-resistance performance and a truly eco-friendly process design.
UPEX Dry Biaxial PP
Features
- Excellent mechanical properties and chemical resistance..
- Pore size distribution control possible through crystallinity and crystal size control.
- Securing improved pore size and uniformity, enabling high air permeability & low resistance (high ion conductivity) due to high porosity.
- Eco-friendly material with minimized carbon emissions and ZERO harmful substance discharge.
- Customization possible (7㎛ – 12㎛, Porosity 45 – 65%).
Application
- Separator for supercapacitors
- Waterproof/breathable membrane for outdoor clothing and viruses
- Protective film for medical PPE (Personal Protective Equipment)

Proactive Environmental Membrane
PFAS-Free
- PFOA (perfluoroalkyl substance) generated during ePTFE manufacturing causes environmental pollution and cancer, leading to the 'Teflon Environmental Scandal'.
- PFOA is scheduled to be banned worldwide by 2027.
- We developed a PFAS-Free ePP Membrane as a compliance solution to these regulations.
Carbon Emission Reduction
- Commercial PO Membrane: 40~50 kgCO2 / kg Membrane
- UPEX Membrane: ~3 kgCO2 / kg Membrane
MC and Harmful Chemicals ZERO
- A strong alternative to international regulations: zero usage of Methylene Chloride (MC) and harmful chemicals.
