- Sealmax Style 9909 is a 100% Multi-directional Expanded PTFE (ePTFE) which is a high-performance sealing material developed to meet the critical demands of a wide range of industrial applications.
- Style 9909 exhibits consistent tensile strength in all directions, providing superior dimensional stability, excellent creep resistance and long-term sealing reliability even under dynamic conditions.
- It prevents cold flow and material relaxation over-time, making it especially suitable for load-sensitive or high-temperature flange connections and ensuring tight sealing across broad spectrum of pressure and temperature ranges.
- Style 9909 has multi-directional strength for uniform mechanical performance and enhanced sealing life.
- Expectational Chemical Resistance: Inert to virtually all corrosive chemicals (pH 0-14)
- Excellent compressibility accommodating flange and irregularities.
- Non-toxic and Non-contaminating: Suitable for high-purity and food-grade applications
- Style 9909 is FDA approved as per US FDA 21 CFR 177.1550
