Features
PTFE-based gasket material, with barium
sulphate filler.
Cold-flow reduced PTFE-based gasket
sheet with high mechanical strength and
chemical resistance as well as optimized
creep resistance.
压力和温度对布拉人操作限制chem with filler (Burachem 9655/B,
W and R) as a function of seal thickness
Consolidation and temperature of pure sintered PTFE compared to Burachem with filler
(Burachem 9655/B, W and R). Contact pressure: 50 N/mm

, seal thickness: 2.0 mm
Advantages
• Excellent chemical resistance
• Excellent mechanical resistance
• Very low gas leakage (complies with
German Fugitive Emission Regulation
TA-Luft)
• Minimized cold-flow and creep behavior
• High density makes this material ideal for
gaskets in steel pipework and equipment
where higher bolt loads are required
• No aging
