The only company in the world capable of producing thin PP membrane below 12μm
Uniform pore size and porosity
Adjustable porosity and thickness
As crystallization increases, molecular arrangement becomes denser, resulting in improved physical performance.
Key properties: hydrophobicity, internal corrosion resistance, thermal stability.
PP membrane production with ZERO environmental pollution.
100% waste recycling.
High-quality, low-cost mass production with UPEX continuous process.
Proprietary dry biaxially stretched process
Uniform pore size → low resistance
Thin separator with excellent durability
Gore-Tex alternative for sports & leisure fabrics
Porous base material for ion-exchange membranes
Lower cost compared to conventional separators
Low defect/loss rate due to simplified manufacturing process
Customer-tailored performance control
In-house design capability for fine-tuned film properties
High-quality films with low noise and excellent breathability
(Fast production line construction, made in Korea)
Wet membranes: 40–50 kg CO₂ / kg separator
UPEX dry membranes: ~3 kg CO₂ / kg separator
→ Significant carbon footprint reduction
MC-Free & PFAS-Free production
In compliance with strict international environmental regulations
Sustainable and future-proof solution
