GYLON® Blue Style 3504  

GYLON® Blue Style 3504 is a PTFE gasket material with aluminosilicate microspheres. It offers much improved performance over standard PTFE and helps reduce product loss and emissions. GYLON® Blue Style 3504 helps minimise cold flow problems typical of expanded PTFE and also has excellent bolt torque retention. As with standard PTFE and other GYLON® materials, it withstands a wide range of chemicals. This material also conforms to FDA regulations and can be cut to meet your specific requirements utilising our in-house CNC machining technology.
