Features of PTFE Expansion Joints
• PTFE Properties: corrosion resistance, can withstand all the Strong acid (except the molten alkali metal, fluoride media and sodium hydroxide ＞300 ℃), strong oxidizing agents, reducing agents and various organic solvents effect;
• Incombustible: limiting oxygen index ＜90;
• Application: used to eliminate pipe or containers stretching or displacement caused by climate change or other reasons; or used as a snubber installed in the import and export of pump or other high frequency machinery to reduce or eliminate vibration;
• Insulation Resistance;
• Self Lubrication: has the minimal friction coefficient in plastics, is an ideal oil-free lubricating materials;
• The surface is not sticky;
• High and low temperature resistance: working temperature can be -100~220℃.
• Superior performance: good corrosion resistance, less business costs;
• Resistance to atmospheric aging, radiation resistance and low permeability: surface and performance remain unchanged even long-term exposed in the air.
Applications Include
