Application
Properties
Application
- Sealmax Style 9900G is a 25% glass fiber reinforced PTFE compound designed to provide improved mechanical strength, wear resistance, and dimensional stability compared to virgin PTFE. It retains the excellent chemical resistance, low coefficient of friction, and wide operating temperature range of PTFE.
Properties
- Style 9900G has excellent chemical resistance to most industrial chemicals.
- Operating temperature range: –200 °C to +260 °C (depending on pressure and load conditions).
- Excellent non-stick characteristics and very low coefficient of friction.
- Improved wear resistance and compressive strength due to glass fiber reinforcement.
- Good dimensional stability under load.
- Style 9900G is typically used in applications like seals, gaskets, valve seats, bearings, pump components, and liners for chemical storage tanks and processing equipment.
