MK 6580 Expanded PTFE sheet

Made of 100% polytetrafluoroethylene through special processing. It has excellent flexibility, excellent compliance performance and forming ability, and has high tensile strength, creep resistance, high and low temperature resistance, corrosion resistance, Anti-cold flow and anti-aging. It can be stored for a long time without deterioration, non-toxic and non-polluting, and is composed of countless homogeneous, dense, soft and tough multi-directional fibers. It has a unique high-density fiber structure. After compression, the fibers will entangle with each other and become tighter and more uniform. It is impermeable to air, impervious to water, and has good anti-leakage performance. It can also maintain an excellent close state under severe corrosive environments and high temperatures.
