Filtration
Nonwovens are ideal for the filtration market because the fabric can be engineered to provide precisely the right porosity and flow rate for each specific filtering application. VINNAPAS® and VINNOL® dispersions are essential binders for filter media. Whether applied as spray, foam or by impregnation, VINNAPAS® VAE dispersions provide excellent fiber bonding for technologically demanding paper and engineered fabric media. Nonwovens coated with VINNOL® ethylene-vinyl chloride copolymer dispersions can be readily heat sealed and HF welded.

Benefits:
- High tensile strength
- Good chemical resistance
- Hydrophobic properties
- High bending stiffness
- Pronounced burst strength
- Long service intervals
- Reliable flame retardancy
Applications:
- Automotive air filters
- Industrial gas filtration
- HVAC filters
- Roofing ventilation
