Product introduction
Aiming at the inert characteristics of chemically corrosive solvents, strong acids and bases that are incompatible with supported PTFE hydrophobic unsupported membrane filters, the hydrophobic unsupported optical membrane provided by HHSTECH is produced by extrusion and biaxial stretching process, with strong chemical stability. High membrane porosity (up to 1.4 billion micropores per square meter). It is suitable for gas and liquid filtration, and can be modified hydrophilic and oleophobic, and can also be used in combination with other supporting materials.
Product advantages
1. Natural hydrophobicity
2. Effective breathability
3. High porosity
4. Chemical resistance and heat resistance
5. Low leachables
6. Good mechanical properties
Application industry
1. Gas filtration
2. Organic solvent filtration
3. Filtration of strong corrosive chemicals
4. Fermentation air sterilization filter
