Introduction：
FlexingSeal? SF700-ePTFE high strength sealing tape is a multi-directionally expanded gasket tape, produced from 100% pure PTFE. The tape is soft, compressible, easy to form, and maintains an extra tight seal even at short loads.
SF700 is made by patented technology with superior tensile strength and dimensional stability. Its excellent creep resistance provides outstanding operational reliability for large steel flange applications, especially those involving thermal cycling.
SF700 can be formed in place into gaskets of any shapes.
Advantages：
Sealing of misalignment or damaged flange.
Superior tensile strength and dimensional stability.
Superior resistance to creep and cold flow.
Excellent sealing properties.
Low diffusion leakage.
Harmless in contact with food.
Properties：
High mechanical properties.
Excellent chemical resistance.
UV resistant, non-aging.
Nontoxic, ensures high levels of Cleanliness.
Applications：
Various types of flanges, large flanges and containers.
Irregularly flanges.
Pressure vessels.
Heat exchangers.
Chemical reactors.
Gas lines and food production systems.
Certificates：
GB 4806.7-2016
ISO 9001:2015
