Features
Burachem Blue 9655/B is a PTFE-based gasket sheet filled with hollow glass microbeads. Burachem B impresses with its high chemical resistance and offers outstanding adaptability compared to similar PTFE-based sheets. Burachem Blue 9655/B seals with relatively low surface pressure, making it especially suitable for applications that offer only low bolt forces.
Advantages
Good adaptability means that only low bolt forces are needed
Intended for use in enamel flanges
