Polytetrafluoroethylene is a fluorinated polymer synthesized from tetrafluoroethylene, which has excellent properties and is suitable for various applications. Due to its high molecular weight combination of carbon and fluorine, PTFE is solid. Its carbon fluorine bond is inert and cannot be broken by other substances. Therefore, PTFE is commonly used in storage tanks and pipelines for active and corrosive chemicals.
Characteristic
Due to its excellent chemical impedance and thermal resistance, it is particularly suitable for hot and cold water, caustic solutions, and concentrated acids. PTFE membranes are particularly suitable for sanitary applications. The chemical inertness of PTFE can prevent cross linking, so it has no "memory" and cannot be restored to its original shape like elastomers. This material undergoes creep and deformation under tension, known as the "cold flow" phenomenon. If PTFE undergoes significant deformation due to temperatures above 130 ° C and significant temperature changes (heating/cooling), it will damage the sealing ring and cause leakage.
We do not recommend using PTFE membranes for applications with significant temperature changes or for applications that require extensive sterilization processes.
Temperature range
Continuous operation from -10°C to +130°C
