CHENGDU MCW PERFORMANCE MATERIALS CO.,LTD

Product introduction

FlexingSeal® SF700 is a high-performance expanded sealing strip made of 100% pure PTFE with bidirectional extrusion technology, which is soft, compressible and easy to form, maintaining a tight seal even at low locking forces.

SF700, manufactured with a special patented technology, has superior tensile strength and dimensional stability compared to other common polytetrafluoroethylene (PTFE) gaskets. As a result, its excellent creep resistance provides excellent operational reliability for large steel flange applications, especially those involving thermal cycling.

The SF700 is a high-performance, field-molded ribbon gasket that fits any shape and is instantly formed, making it ideal for irregularly shaped steel flanges and glass-lined flanges.
